# Troubleshoot
This guide provides solutions to some issues you might encounter when using Accelerate. Not all errors are covered because Accelerate is an active library that is continuously evolving and there are many different use cases and distributed training setups. If the solutions described here don't help with your specific error, please take a look at the [Ask for help](#ask-for-help) section to learn where and how to get help.
## Logging
Logging can help you identify where an error is coming from. In a distributed setup with multiple processes, logging can be a challenge, but Accelerate provides the [`~accelerate.logging`] utility to ensure logs are synchronized.
To troubleshoot an issue, use [`~accelerate.logging`] instead of the standard Python [`logging`](https://docs.python.org/3/library/logging.html#module-logging) module. Set the verbosity level (`INFO`, `DEBUG`, `WARNING`, `ERROR`, `CRITICAL`) with the `log_level` parameter, and then you can either:
1. Export the `log_level` as the `ACCELERATE_LOG_LEVEL` environment variable.
2. Pass the `log_level` directly to `get_logger`.
For example, to set `log_level="INFO"`:
```py
from accelerate.logging import get_logger
logger = get_logger(__name__, log_level="DEBUG")
```
By default, the log is called on main processes only. To call it on all processes, pass `main_process_only=False`.
If a log should be called on all processes and in order, also pass `in_order=True`.
```py
from accelerate.logging import get_logger
logger = get_logger(__name__, log_level="DEBUG")
# log all processes
logger.debug("thing_to_log", main_process_only=False)
# log all processes in order
logger.debug("thing_to_log", main_process_only=False, in_order=True)
```
## Hanging code and timeout errors
There can be many reasons why your code is hanging. Let's take a look at how to solve some of the most common issues that can cause your code to hang.
### Mismatched tensor shapes
Mismatched tensor shapes is a common issue that can cause your code to hang for a significant amount of time on a distributed setup.
When running scripts in a distributed setup, functions such as [`Accelerator.gather`] and [`Accelerator.reduce`] are necessary to grab tensors across devices to collectively perform operations on them. These (and other) functions rely on `torch.distributed` to perform a `gather` operation, which requires tensors to have the **exact same shape** across all processes. When the tensor shapes don't match, your code hangs and you'll eventually hit a timeout exception.
You can use Accelerate's operational debug mode to immediately catch this issue. We recommend enabling this mode during the `accelerate config` setup, but you can also enable it from the CLI, as an environment variable, or by manually editing the `config.yaml` file.
<hfoptions id="mismatch">
<hfoption id="CLI">
```bash
accelerate launch --debug {my_script.py} --arg1 --arg2
```
</hfoption>
<hfoption id="environment variable">
If enabling debug mode as an environment variable, you don't need to call `accelerate launch`.
```bash
ACCELERATE_DEBUG_MODE="1" torchrun {my_script.py} --arg1 --arg2
```
</hfoption>
<hfoption id="config.yaml">
Add `debug: true` to your `config.yaml` file.
```yaml
compute_environment: LOCAL_MACHINE
debug: true
```
</hfoption>
</hfoptions>
Once you enable debug mode, you should get a traceback that points to the tensor shape mismatch issue.
```py
Traceback (most recent call last):
File "/home/zach_mueller_huggingface_co/test.py", line 18, in <module>
main()
File "/home/zach_mueller_huggingface_co/test.py", line 15, in main
broadcast_tensor = broadcast(tensor)
File "/home/zach_mueller_huggingface_co/accelerate/src/accelerate/utils/operations.py", line 303, in wrapper
accelerate.utils.operations.DistributedOperationException:
Cannot apply desired operation due to shape mismatches. All shapes across devices must be valid.
Operation: `accelerate.utils.operations.broadcast`
Input shapes:
- Process 0: [1, 5]
- Process 1: [1, 2, 5]
```
### Early stopping
For early stopping in distributed training, if each process has a specific stopping condition (e.g. validation loss), it may not be synchronized across all processes. As a result, a break can happen on process 0 but not on process 1 which will cause your code to hang indefinitely until a timeout occurs.
If you have early stopping conditionals, use the `set_breakpoint` and `check_breakpoint` methods to make sure all the processes
are ended correctly.
```py
# Assume `should_do_breakpoint` is a custom defined function that returns a conditional,
# and that conditional might be true only on process 1
if should_do_breakpoint(loss):
accelerator.set_breakpoint()
# Later in the training script when we need to check for the breakpoint
if accelerator.check_breakpoint():
break
```
### Low kernel versions on Linux
On Linux with kernel version < 5.5, hanging processes have been reported. To avoid this problem, upgrade your system to a later kernel version.
### MPI
If your distributed CPU training job using MPI is hanging, ensure that you have
[passwordless SSH](https://www.open-mpi.org/faq/?category=rsh#ssh-keys) setup (using keys) between the nodes. This means
that for all nodes in your hostfile, you should to be able to SSH from one node to another without being prompted for a password.
Next, try to run the `mpirun` command as a sanity check. For example, the command below should print out the
hostnames for each of the nodes.
```bash
mpirun -f hostfile -n {number of nodes} -ppn 1 hostname
```
## CUDA Out-of-Memory
One of the most frustrating errors when it comes to running training scripts is hitting "CUDA Out-of-Memory". The entire script needs to be restarted and any progress is lost.
To address this problem, Accelerate provides the [`find_executable_batch_size`] utility that is heavily based on [toma](https://github.com/BlackHC/toma).
This utility retries code that fails due to OOM (out-of-memory) conditions and automatically lowers batch sizes. For each OOM condition, the algorithm decreases the batch size by half and retries the code until it succeeds.
To use [`find_executable_batch_size`], restructure your training function to include an inner function with `find_executable_batch_size` and build your dataloaders inside it. At a minimum, this only takes 4 new lines of code.
<Tip warning={true}>
The inner function **must** take batch size as the first parameter, but we do not pass one to it when called. The wrapper will handles this for you. Any object (models, optimizers) that consumes CUDA memory and is passed to the [`Accelerator`] also **must** be declared inside the inner function.
</Tip>
```diff
def training_function(args):
accelerator = Accelerator()
+ @find_executable_batch_size(starting_batch_size=args.batch_size)
+ def inner_training_loop(batch_size):
+ nonlocal accelerator # Ensure they can be used in our context
+ accelerator.free_memory() # Free all lingering references
model = get_model()
model.to(accelerator.device)
optimizer = get_optimizer()
train_dataloader, eval_dataloader = get_dataloaders(accelerator, batch_size)
lr_scheduler = get_scheduler(
optimizer,
num_training_steps=len(train_dataloader)*num_epochs
)
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
train(model, optimizer, train_dataloader, lr_scheduler)
validate(model, eval_dataloader)
+ inner_training_loop()
```
## Non-reproducible results between device setups
If you changed the device setup and observe different model performance, it is likely you didn't update your script when moving from one setup to another. Even if you're using the same script with the same batch size, the results will still be different on a TPU, multi-GPU, and single GPU.
For example, if you were training on a single GPU with a batch size of 16 and you move to a dual GPU setup, you need to change the batch size to 8 to have the same effective batch size. This is because when training with Accelerate, the batch size passed to the dataloader is the **batch size per GPU**.
To make sure you can reproduce the results between the setups, make sure to use the same seed, adjust the batch size accordingly, and consider scaling the learning rate.
For more details and a quick reference for batch sizes, check out the [Comparing performance between different device setups](../concept_guides/performance) guide.
## Performance issues on different GPUs
If your multi-GPU setup consists of different GPUs, you may encounter some performance issues:
- There may be an imbalance in GPU memory between the GPUs. In this case, the GPU with the smaller memory will limit the batch size or the size of the model that can be loaded onto the GPUs.
- If you are using GPUs with different performance profiles, the performance will be driven by the slowest GPU you are using because the other GPUs will have to wait for it to complete its workload.
Vastly different GPUs within the same setup can lead to performance bottlenecks.
## Ask for help
If none of the solutions and advice here helped resolve your issue, you can always reach out to the community and Accelerate team for help.
- Ask for help on the Hugging Face forums by posting your question in the [๐ค Accelerate category](https://discuss.huggingface.co/c/accelerate/18). Make sure to write a descriptive post with relevant context about your setup and reproducible code to maximize the likelihood that your problem is solved!
- Post a question on [Discord](http://hf.co/join/discord), and let the team and the community help you.
- Create an Issue on the ๐ค Accelerate [GitHub repository](https://github.com/huggingface/accelerate/issues) if you think you've found a bug related to the library. Include context regarding the bug and details about your distributed setup to help us better figure out what's wrong and how we can fix it.

# DeepSpeed
[DeepSpeed](https://github.com/microsoft/DeepSpeed) implements everything described in the [ZeRO paper](https://arxiv.org/abs/1910.02054). Some of the salient optimizations are:
1. Optimizer state partitioning (ZeRO stage 1)
2. Gradient partitioning (ZeRO stage 2)
3. Parameter partitioning (ZeRO stage 3)
4. Custom mixed precision training handling
5. A range of fast CUDA-extension-based optimizers
6. ZeRO-Offload to CPU and Disk/NVMe
7. Hierarchical partitioning of model parameters (ZeRO++)
ZeRO-Offload has its own dedicated paper: [ZeRO-Offload: Democratizing Billion-Scale Model Training](https://arxiv.org/abs/2101.06840). And NVMe-support is described in the paper [ZeRO-Infinity: Breaking the GPU
Memory Wall for Extreme Scale Deep Learning](https://arxiv.org/abs/2104.07857).
DeepSpeed ZeRO-2 is primarily used only for training, as its features are of no use to inference.
DeepSpeed ZeRO-3 can be used for inference as well since it allows huge models to be loaded on multiple GPUs, which
won't be possible on a single GPU.
๐ค Accelerate integrates [DeepSpeed](https://github.com/microsoft/DeepSpeed) via 2 options:
1. Integration of the DeepSpeed features via `deepspeed config file` specification in `accelerate config` . You just supply your custom config file or use our template. Most of
this document is focused on this feature. This supports all the core features of DeepSpeed and gives user a lot of flexibility.
User may have to change a few lines of code depending on the config.
2. Integration via `deepspeed_plugin`.This supports subset of the DeepSpeed features and uses default options for the rest of the configurations.
User need not change any code and is good for those who are fine with most of the default settings of DeepSpeed.
## What is integrated?
Training:
1. ๐ค Accelerate integrates all features of DeepSpeed ZeRO. This includes all the ZeRO stages 1, 2 and 3 as well as ZeRO-Offload, ZeRO-Infinity (which can offload to disk/NVMe) and ZeRO++.
Below is a short description of Data Parallelism using ZeRO - Zero Redundancy Optimizer along with diagram from this [blog post](https://www.microsoft.com/en-us/research/blog/zero-deepspeed-new-system-optimizations-enable-training-models-with-over-100-billion-parameters/)
(Source: [link](https://www.microsoft.com/en-us/research/blog/zero-deepspeed-new-system-optimizations-enable-training-models-with-over-100-billion-parameters/))
a. **Stage 1** : Shards optimizer states across data parallel workers/GPUs
b. **Stage 2** : Shards optimizer states + gradients across data parallel workers/GPUs
c. **Stage 3**: Shards optimizer states + gradients + model parameters across data parallel workers/GPUs
d. **Optimizer Offload**: Offloads the gradients + optimizer states to CPU/Disk building on top of ZERO Stage 2
e. **Param Offload**: Offloads the model parameters to CPU/Disk building on top of ZERO Stage 3
f. **Hierarchical Partitioning**: Enables efficient multi-node training with data-parallel training across nodes and ZeRO-3 sharding within a node, built on top of ZeRO Stage 3.
<u>Note</u>: With respect to Disk Offload, the disk should be an NVME for decent speed but it technically works on any Disk
Inference:
1. DeepSpeed ZeRO Inference supports ZeRO stage 3 with ZeRO-Infinity. It uses the same ZeRO protocol as training, but
it doesn't use an optimizer and a lr scheduler and only stage 3 is relevant. For more details see:
[deepspeed-zero-inference](#deepspeed-zero-inference).
## How it works?
**Pre-Requisites**: Install DeepSpeed version >=0.6.5. Please refer to the [DeepSpeed Installation details](https://github.com/microsoft/DeepSpeed#installation)
for more information.
We will first look at easy to use integration via `accelerate config`.
Followed by more flexible and feature rich `deepspeed config file` integration.
### Accelerate DeepSpeed Plugin
On your machine(s) just run:
```bash
accelerate config
```
and answer the questions asked. It will ask whether you want to use a config file for DeepSpeed to which you should answer no. Then answer the following questions to generate a basic DeepSpeed config.
This will generate a config file that will be used automatically to properly set the
default options when doing
```bash
accelerate launch my_script.py --args_to_my_script
```
For instance, here is how you would run the NLP example `examples/nlp_example.py` (from the root of the repo) with DeepSpeed Plugin:
**ZeRO Stage-2 DeepSpeed Plugin Example**
```bash
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: none
offload_param_device: none
zero3_init_flag: true
zero_stage: 2
distributed_type: DEEPSPEED
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
```bash
accelerate launch examples/nlp_example.py --mixed_precision fp16
```
**ZeRO Stage-3 with CPU Offload DeepSpeed Plugin Example**
```bash
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: cpu
offload_param_device: cpu
zero3_init_flag: true
zero3_save_16bit_model: true
zero_stage: 3
distributed_type: DEEPSPEED
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
```bash
accelerate launch examples/nlp_example.py --mixed_precision fp16
```
Currently, `Accelerate` supports following config through the CLI:
```bash
`zero_stage`: [0] Disabled, [1] optimizer state partitioning, [2] optimizer+gradient state partitioning and [3] optimizer+gradient+parameter partitioning
`gradient_accumulation_steps`: Number of training steps to accumulate gradients before averaging and applying them.
`gradient_clipping`: Enable gradient clipping with value.
`offload_optimizer_device`: [none] Disable optimizer offloading, [cpu] offload optimizer to CPU, [nvme] offload optimizer to NVMe SSD. Only applicable with ZeRO >= Stage-2.
`offload_optimizer_nvme_path`: Decides Nvme Path to offload optimizer states. If unspecified, will default to 'none'.
`offload_param_device`: [none] Disable parameter offloading, [cpu] offload parameters to CPU, [nvme] offload parameters to NVMe SSD. Only applicable with ZeRO Stage-3.
`offload_param_nvme_path`: Decides Nvme Path to offload parameters. If unspecified, will default to 'none'.
`zero3_init_flag`: Decides whether to enable `deepspeed.zero.Init` for constructing massive models. Only applicable with ZeRO Stage-3.
`zero3_save_16bit_model`: Decides whether to save 16-bit model weights when using ZeRO Stage-3.
`mixed_precision`: `no` for FP32 training, `fp16` for FP16 mixed-precision training and `bf16` for BF16 mixed-precision training.
`deepspeed_moe_layer_cls_names`: Comma-separated list of transformer Mixture-of-Experts (MoE) layer class names (case-sensitive) to wrap ,e.g, `MixtralSparseMoeBlock`, `Qwen2MoeSparseMoeBlock`, `JetMoEAttention,JetMoEBlock` ...
`deepspeed_hostfile`: DeepSpeed hostfile for configuring multi-node compute resources.
`deepspeed_exclusion_filter`: DeepSpeed exclusion filter string when using mutli-node setup.
`deepspeed_inclusion_filter`: DeepSpeed inclusion filter string when using mutli-node setup.
`deepspeed_multinode_launcher`: DeepSpeed multi-node launcher to use. If unspecified, will default to `pdsh`.
`deepspeed_config_file`: path to the DeepSpeed config file in `json` format. See the next section for more details on this.
```
To be able to tweak more options, you will need to use a DeepSpeed config file.
### DeepSpeed Config File
On your machine(s) just run:
```bash
accelerate config
```
and answer the questions asked. It will ask whether you want to use a config file for deepspeed to which you answer yes
and provide the path to the deepspeed config file.
This will generate a config file that will be used automatically to properly set the
default options when doing
```bash
accelerate launch my_script.py --args_to_my_script
```
For instance, here is how you would run the NLP example `examples/by_feature/deepspeed_with_config_support.py` (from the root of the repo) with DeepSpeed Config File:
**ZeRO Stage-2 DeepSpeed Config File Example**
```bash
compute_environment: LOCAL_MACHINE
deepspeed_config:
deepspeed_config_file: /home/ubuntu/accelerate/examples/configs/deepspeed_config_templates/zero_stage2_config.json
zero3_init_flag: true
distributed_type: DEEPSPEED
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
with the contents of `zero_stage2_config.json` being:
```json

**ZeRO++ Config Example**
You can use the features of ZeRO++ by using the appropriate config parameters. Note that ZeRO++ is an extension for ZeRO Stage 3. Here is how the config file can be modified, from [DeepSpeed's ZeRO++ tutorial](https://www.deepspeed.ai/tutorials/zeropp/):
```json
{
"zero_optimization": {
"stage": 3,
"reduce_bucket_size": "auto",
"zero_quantized_weights": true,
"zero_hpz_partition_size": 8,
"zero_quantized_gradients": true,
"contiguous_gradients": true,
"overlap_comm": true
}
}
```
For hierarchical partitioning, the partition size `zero_hpz_partition_size` should ideally be set to the number of GPUs per node. (For example, the above config file assumes 8 GPUs per node)
**Important code changes when using DeepSpeed Config File**
1. DeepSpeed Optimizers and Schedulers. For more information on these,
see the [DeepSpeed Optimizers](https://deepspeed.readthedocs.io/en/latest/optimizers.html) and [DeepSpeed Schedulers](https://deepspeed.readthedocs.io/en/latest/schedulers.html) documentation.
We will look at the changes needed in the code when using these.
a. DS Optim + DS Scheduler: The case when both `optimizer` and `scheduler` keys are present in the DeepSpeed config file.
In this situation, those will be used and the user has to use `accelerate.utils.DummyOptim` and `accelerate.utils.DummyScheduler` to replace the PyTorch/Custom optimizers and schedulers in their code.
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
# Creates Dummy Optimizer if `optimizer` was specified in the config file else creates Adam Optimizer
optimizer_cls = (
torch.optim.AdamW
if accelerator.state.deepspeed_plugin is None
or "optimizer" not in accelerator.state.deepspeed_plugin.deepspeed_config
else DummyOptim
)
optimizer = optimizer_cls(optimizer_grouped_parameters, lr=args.learning_rate)
# Creates Dummy Scheduler if `scheduler` was specified in the config file else creates `args.lr_scheduler_type` Scheduler
if (
accelerator.state.deepspeed_plugin is None
or "scheduler" not in accelerator.state.deepspeed_plugin.deepspeed_config
):
lr_scheduler = get_scheduler(
name=args.lr_scheduler_type,
optimizer=optimizer,
num_warmup_steps=args.num_warmup_steps,
num_training_steps=args.max_train_steps,
)
else:
lr_scheduler = DummyScheduler(
optimizer, total_num_steps=args.max_train_steps, warmup_num_steps=args.num_warmup_steps
)
```
b. Custom Optim + Custom Scheduler: The case when both `optimizer` and `scheduler` keys are absent in the DeepSpeed config file.
In this situation, no code changes are needed from the user and this is the case when using integration via DeepSpeed Plugin.
In the above example we can see that the code remains unchanged if the `optimizer` and `scheduler` keys are absent in the DeepSpeed config file.
c. Custom Optim + DS Scheduler: The case when only `scheduler` key is present in the DeepSpeed config file.
In this situation, the user has to use `accelerate.utils.DummyScheduler` to replace the PyTorch/Custom scheduler in their code.
d. DS Optim + Custom Scheduler: The case when only `optimizer` key is present in the DeepSpeed config file.
This will result in an error because you can only use DS Scheduler when using DS Optim.
2. Notice the `auto` values in the above example DeepSpeed config files. These are automatically handled by `prepare` method
based on model, dataloaders, dummy optimizer and dummy schedulers provided to `prepare` method.
Only the `auto` fields specified in above examples are handled by `prepare` method and the rest have to be explicitly specified by the user.
The `auto` values are calculated as:
- `reduce_bucket_size`: `hidden_size * hidden_size`
- `stage3_prefetch_bucket_size`: `int(0.9 * hidden_size * hidden_size)`
- `stage3_param_persistence_threshold`: `10 * hidden_size`
For the `auto` feature to work for these 3 config entries - Accelerate will use `model.config.hidden_size` or `max(model.config.hidden_sizes)` as `hidden_size`. If neither of these is available, the launching will fail and you will have to set these 3 config entries manually. Remember the first 2 config entries are the communication buffers - the larger they are the more efficient the comms will be, and the larger they are the more GPU memory they will consume, so it's a tunable performance trade-off.
**Things to note when using DeepSpeed Config File**
Below is a sample script using `deepspeed_config_file` in different scenarios.
Code `test.py`:
```python
from accelerate import Accelerator
from accelerate.state import AcceleratorState
def main():
accelerator = Accelerator()
accelerator.print(f"{AcceleratorState()}")
if __name__ == "__main__":
main()
```
**Scenario 1**: Manually tampered accelerate config file having `deepspeed_config_file` along with other entries.
1. Content of the `accelerate` config:
```yaml
command_file: null
commands: null
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: 'cpu'
offload_param_device: 'cpu'
zero3_init_flag: true
zero3_save_16bit_model: true
zero_stage: 3
deepspeed_config_file: 'ds_config.json'
distributed_type: DEEPSPEED
downcast_bf16: 'no'
dynamo_backend: 'NO'
fsdp_config: {}
gpu_ids: null
machine_rank: 0

num_machines: 1
num_processes: 2
rdzv_backend: static
same_network: true
tpu_name: null
tpu_zone: null
use_cpu: false
```
2. `ds_config.json`:
```json
{
"bf16": {
"enabled": true
},
"zero_optimization": {
"stage": 3,
"stage3_gather_16bit_weights_on_model_save": false,
"offload_optimizer": {
"device": "none"
},
"offload_param": {
"device": "none"
}
},
"gradient_clipping": 1.0,
"train_batch_size": "auto",
"train_micro_batch_size_per_gpu": "auto",
"gradient_accumulation_steps": 10,
"steps_per_print": 2000000
}
```
3. Output of `accelerate launch test.py`:
```bash
ValueError: When using `deepspeed_config_file`, the following accelerate config variables will be ignored:
['gradient_accumulation_steps', 'gradient_clipping', 'zero_stage', 'offload_optimizer_device', 'offload_param_device',
'zero3_save_16bit_model', 'mixed_precision'].
Please specify them appropriately in the DeepSpeed config file.
If you are using an accelerate config file, remove other config variables mentioned in the above specified list.
The easiest method is to create a new config following the questionnaire via `accelerate config`.
It will only ask for the necessary config variables when using `deepspeed_config_file`.
```
**Scenario 2**: Use the solution of the error to create new accelerate config and check that no ambiguity error is now thrown.
1. Run `accelerate config`:
```bash
$ accelerate config
-------------------------------------------------------------------------------------------------------------------------------
In which compute environment are you running?
This machine
-------------------------------------------------------------------------------------------------------------------------------
Which type of machine are you using?
multi-GPU
How many different machines will you use (use more than 1 for multi-node training)? [1]:
Do you wish to optimize your script with torch dynamo?[yes/NO]:
Do you want to use DeepSpeed? [yes/NO]: yes
Do you want to specify a json file to a DeepSpeed config? [yes/NO]: yes
Please enter the path to the json DeepSpeed config file: ds_config.json
Do you want to enable `deepspeed.zero.Init` when using ZeRO Stage-3 for constructing massive models? [yes/NO]: yes
How many GPU(s) should be used for distributed training? [1]:4
accelerate configuration saved at ds_config_sample.yaml
```
2. Content of the `accelerate` config:
```yaml
compute_environment: LOCAL_MACHINE
deepspeed_config:
deepspeed_config_file: ds_config.json
zero3_init_flag: true
distributed_type: DEEPSPEED
downcast_bf16: 'no'
dynamo_backend: 'NO'
fsdp_config: {}
machine_rank: 0
main_training_function: main
megatron_lm_config: {}
num_machines: 1
num_processes: 4
rdzv_backend: static
same_network: true
use_cpu: false
```
3. Output of `accelerate launch test.py`:
```bash
Distributed environment: DEEPSPEED Backend: nccl
Num processes: 4
Process index: 0
Local process index: 0
Device: cuda:0
Mixed precision type: bf16
ds_config: {'bf16': {'enabled': True}, 'zero_optimization': {'stage': 3, 'stage3_gather_16bit_weights_on_model_save': False, 'offload_optimizer': {'device': 'none'}, 'offload_param': {'device': 'none'}}, 'gradient_clipping': 1.0, 'train_batch_size': 'auto', 'train_micro_batch_size_per_gpu': 'auto', 'gradient_accumulation_steps': 10, 'steps_per_print': inf, 'fp16': {'enabled': False}}
```
**Scenario 3**: Setting the `accelerate launch` command arguments related to DeepSpeed as `"auto"` in the DeepSpeed` configuration file and check that things work as expected.
1. New `ds_config.json` with `"auto"` for the `accelerate launch` DeepSpeed command arguments:
```json
{
"bf16": {
"enabled": "auto"
},
"zero_optimization": {
"stage": "auto",
"stage3_gather_16bit_weights_on_model_save": "auto",
"offload_optimizer": {
"device": "auto"
},
"offload_param": {
"device": "auto"
}
},
"gradient_clipping": "auto",
"train_batch_size": "auto",
"train_micro_batch_size_per_gpu": "auto",
"gradient_accumulation_steps": "auto",
"steps_per_print": 2000000
}
```
2. Output of `accelerate launch --mixed_precision="fp16" --zero_stage=3 --gradient_accumulation_steps=5 --gradient_clipping=1.0 --offload_param_device="cpu" --offload_optimizer_device="nvme" --zero3_save_16bit_model="true" test.py`:
```bash
Distributed environment: DEEPSPEED Backend: nccl
Num processes: 4
Process index: 0
Local process index: 0
Device: cuda:0
Mixed precision type: fp16
ds_config: {'bf16': {'enabled': False}, 'zero_optimization': {'stage': 3, 'stage3_gather_16bit_weights_on_model_save': True, 'offload_optimizer': {'device': 'nvme'}, 'offload_param': {'device': 'cpu'}}, 'gradient_clipping': 1.0, 'train_batch_size': 'auto', 'train_micro_batch_size_per_gpu': 'auto', 'gradient_accumulation_steps': 5, 'steps_per_print': inf, 'fp16': {'enabled': True, 'auto_cast': True}}
```
**Note**:
1. Remaining `"auto"` values are handled in `accelerator.prepare()` call as explained in point 2 of
`Important code changes when using DeepSpeed Config File`.
2. Only when `gradient_accumulation_steps` is `auto`, the value passed while creating `Accelerator` object via `Accelerator(gradient_accumulation_steps=k)` will be used. When using DeepSpeed Plugin, the value from it will be used and it will overwrite the value passed while creating Accelerator object.
## Saving and loading
1. Saving and loading of models is unchanged for ZeRO Stage-1 and Stage-2.
2. under ZeRO Stage-3, `state_dict` contains just the placeholders since the model weights are partitioned across multiple GPUs.
ZeRO Stage-3 has 2 options:
a. Saving the entire 16bit model weights to directly load later on using `model.load_state_dict(torch.load(pytorch_model.bin))`.
For this, either set `zero_optimization.stage3_gather_16bit_weights_on_model_save` to True in DeepSpeed Config file or set
`zero3_save_16bit_model` to True in DeepSpeed Plugin.
**Note that this option requires consolidation of the weights on one GPU it can be slow and memory demanding, so only use this feature when needed.**
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
unwrapped_model = accelerator.unwrap_model(model)
# New Code #
# Saves the whole/unpartitioned fp16 model when in ZeRO Stage-3 to the output directory if
# `stage3_gather_16bit_weights_on_model_save` is True in DeepSpeed Config file or
# `zero3_save_16bit_model` is True in DeepSpeed Plugin.
# For Zero Stages 1 and 2, models are saved as usual in the output directory.
# The model name saved is `pytorch_model.bin`
unwrapped_model.save_pretrained(
args.output_dir,
is_main_process=accelerator.is_main_process,
save_function=accelerator.save,
state_dict=accelerator.get_state_dict(model),
)
```
b. To get 32bit weights, first save the model using `model.save_checkpoint()`.
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
success = model.save_checkpoint(PATH, ckpt_id, checkpoint_state_dict)
status_msg = f"checkpointing: PATH={PATH}, ckpt_id={ckpt_id}"
if success:
logging.info(f"Success {status_msg}")
else:
logging.warning(f"Failure {status_msg}")
```
This will create ZeRO model and optimizer partitions along with `zero_to_fp32.py` script in checkpoint directory.
You can use this script to do offline consolidation.
It requires no configuration files or GPUs. Here is an example of its usage:
```bash
$ cd /path/to/checkpoint_dir
$ ./zero_to_fp32.py . pytorch_model.bin
Processing zero checkpoint at global_step1
Detected checkpoint of type zero stage 3, world_size: 2
Saving fp32 state dict to pytorch_model.bin (total_numel=60506624)
```
To get 32bit model for saving/inference, you can perform:
```python
from deepspeed.utils.zero_to_fp32 import load_state_dict_from_zero_checkpoint
unwrapped_model = accelerator.unwrap_model(model)
fp32_model = load_state_dict_from_zero_checkpoint(unwrapped_model, checkpoint_dir)
```
If you are only interested in the `state_dict`, you can do the following:
```python
from deepspeed.utils.zero_to_fp32 import get_fp32_state_dict_from_zero_checkpoint
state_dict = get_fp32_state_dict_from_zero_checkpoint(checkpoint_dir)
```
Note that all these functions require ~2x memory (general RAM) of the size of the final checkpoint.
## ZeRO Inference
DeepSpeed ZeRO Inference supports ZeRO stage 3 with ZeRO-Infinity.
It uses the same ZeRO protocol as training, but it doesn't use an optimizer and a lr scheduler and only stage 3 is relevant.
With accelerate integration, you just need to prepare the model and dataloader as shown below:
```python
model, eval_dataloader = accelerator.prepare(model, eval_dataloader)
```
## Few caveats to be aware of
1. Current integration doesnโt support Pipeline Parallelism of DeepSpeed.
2. Current integration doesnโt support `mpu`, limiting the tensor parallelism which is supported in Megatron-LM.
3. Current integration doesnโt support multiple models.

# In this folder we showcase various full examples using ๐ค Accelerate
## Simple NLP example
The [nlp_example.py](./nlp_example.py) script is a simple example to train a Bert model on a classification task ([GLUE's MRPC](https://www.microsoft.com/en-us/download/details.aspx?id=52398)).
Prior to running it you should install ๐ค Dataset and ๐ค Transformers:
```bash
pip install datasets evaluate transformers
```
The same script can be run in any of the following configurations:
- single CPU or single GPU
- multi CPUs
- multi GPUs (using PyTorch distributed mode)
- (multi) TPUs
- fp16 (mixed-precision) or fp32 (normal precision)
To run it in each of these various modes, use the following commands:
- single CPU:
* from a server without GPU
```bash
python ./nlp_example.py
```
* from any server by passing `cpu=True` to the `Accelerator`.
```bash
python ./nlp_example.py --cpu
```
* from any server with Accelerate launcher
```bash
accelerate launch --cpu ./nlp_example.py
```
- single GPU:
```bash
python ./nlp_example.py # from a server with a GPU
```
- with fp16 (mixed-precision)
* from any server by passing `mixed_precison=fp16` to the `Accelerator`.
```bash
python ./nlp_example.py --mixed_precision fp16
```
* from any server with Accelerate launcher
```bash
accelerate launch --mixed_precision fp16 ./nlp_example.py
- multi CPUs (requires Open MPI, Intel MPI, or MVAPICH)
* With Accelerate config and launcher, execute the following from node 0:
```bash
accelerate config # Select to have accelerate launch mpirun
accelerate launch ./nlp_example.py # This will run the script on each server
```
* With Intel MPI:
```bash
export CCL_WORKER_COUNT=1
export MASTER_ADDR=xxx.xxx.xxx.xxx #node0 ip
mpirun -f hostfile -n 16 -ppn 4 python ./nlp_example.py
```
- multi GPUs (using PyTorch distributed mode)
* With Accelerate config and launcher
```bash
accelerate config # This will create a config file on your server
accelerate launch ./nlp_example.py # This will run the script on your server
```
* With traditional PyTorch launcher (`python -m torch.distributed.run` can be used instead of `torchrun`)
```bash
torchrun --nproc_per_node 2 ./nlp_example.py
```
- multi GPUs, multi node (several machines, using PyTorch distributed mode)
* With Accelerate config and launcher, on each machine:
```bash
accelerate config # This will create a config file on each server
accelerate launch ./nlp_example.py # This will run the script on each server
```
* With PyTorch launcher only (`python -m torch.distributed.run` can be used instead of `torchrun`). Run this command on each node:
```bash
torchrun \ # python -m torch.distributed.run
--nproc_per_node 2 \
--nnodes 2 \
--rdzv_id 2299 \ # A unique job id
--rdzv_backend c10d \
--rdzv_endpoint master_node_ip_address:29500 \
./nlp_example.py
```
- (multi) TPUs
* With Accelerate config and launcher
```bash
accelerate config # This will create a config file on your TPU server
accelerate launch ./nlp_example.py # This will run the script on each server
```
* In PyTorch:
Add an `xmp.spawn` line in your script as you usually do.
## Simple vision example
The [cv_example.py](./cv_example.py) script is a simple example to fine-tune a ResNet-50 on a classification task ([Ofxord-IIT Pet Dataset](https://www.robots.ox.ac.uk/~vgg/data/pets/)).
The same script can be run in any of the following configurations:
- single CPU or single GPU
- multi CPUs
- multi GPUs (using PyTorch distributed mode)
- (multi) TPUs
- fp16 (mixed-precision) or fp32 (normal precision)
Prior to running it you should install timm and torchvision:
```bash
pip install timm torchvision
```
and you should download the data with the following commands:
```bash
wget https://www.robots.ox.ac.uk/~vgg/data/pets/data/images.tar.gz
tar -xzf images.tar.gz
```
To run it in each of these various modes, use the following commands:
- single CPU:
* from a server without GPU
```bash
python ./cv_example.py --data_dir path_to_data
```
* from any server by passing `cpu=True` to the `Accelerator`.
```bash
python ./cv_example.py --data_dir path_to_data --cpu
```
* from any server with Accelerate launcher
```bash
accelerate launch --cpu ./cv_example.py --data_dir path_to_data
```
- single GPU:
```bash
python ./cv_example.py # from a server with a GPU
```
- with fp16 (mixed-precision)
* from any server by passing `mixed_precison=fp16` to the `Accelerator`.
```bash
python ./cv_example.py --data_dir path_to_data --mixed_precison fp16
```
* from any server with Accelerate launcher
```bash
accelerate launch --mixed_precison fp16 ./cv_example.py --data_dir path_to_data
- multi CPUs (requires Open MPI, Intel MPI, or MVAPICH)
* With Accelerate config and launcher, run the following from node 0:
```bash
accelerate config --config_file config.yaml # Select to have accelerate launch mpirun
accelerate launch ./cv_example.py --data_dir path_to_data # This will run the script on each server
```
* With Intel MPI, execute mpirun from node 0:
```bash
export CCL_WORKER_COUNT=1
export MASTER_ADDR=xxx.xxx.xxx.xxx #node0 ip
mpirun -f hostfile -n 16 -ppn 4 python ./cv_example.py --data_dir path_to_data
```
- multi GPUs (using PyTorch distributed mode)
* With Accelerate config and launcher
```bash
accelerate config --config_file config.yaml # This will create a config file on your server to `config.yaml`
accelerate launch --config_file config.yaml ./cv_example.py --data_dir path_to_data # This will run the script on your server
```
* With traditional PyTorch launcher (`python -m torch.distributed.run` can be used instead of `torchrun`)
```bash
torchrun --nproc_per_node 2 ./cv_example.py --data_dir path_to_data
```
- multi GPUs, multi node (several machines, using PyTorch distributed mode)
* With Accelerate config and launcher, on each machine:
```bash
accelerate config --config_file config.yaml # This will create a config file on your server to `config.yaml`
accelerate launch --config_file config.yaml ./cv_example.py --data_dir path_to_data # This will run the script on each server
```
* With PyTorch launcher only (`python -m torch.distributed.run` can be used instead of `torchrun`). Run this command on each node:
```bash
torchrun \ # python -m torch.distributed.run
--nproc_per_node 2 \
--nnodes 2 \
--rdzv_id 2299 \ # A unique job id
--rdzv_backend c10d \
--rdzv_endpoint master_node_ip_address:29500 \
./cv_example.py --data_dir path_to_data
```
- (multi) TPUs
* With Accelerate config and launcher
```bash
accelerate config --config_file config.yaml # This will create a config file on your server to `config.yaml`
accelerate launch --config_file config.yaml ./cv_example.py --data_dir path_to_data # This will run the script on each server
```
* In PyTorch:
Add an `xmp.spawn` line in your script as you usually do.

### Using AWS SageMaker integration
- [Examples showcasing AWS SageMaker integration of ๐ค Accelerate.](https://github.com/pacman100/accelerate-aws-sagemaker)
## Configuration zoo
In [/config_yaml_templates](./config_yaml_templates/) we have a variety of *minimal* `config.yaml` templates and examples to help you learn
how to create your own configuration files depending on the scenario.
## SLURM Scripts
In [/slurm/submit_multigpu.sh](./slurm/submit_multigpu.sh) and [/slurm/submit_multinode.sh](./slurm/submit_multinode.sh) we present two scripts for running the examples on a machine with [SLURM](https://slurm.schedmd.com/documentation.html) workload manager.
In [/slurm/submit_multigpu.sh](./slurm/submit_multigpu.sh) the only parameter in the launcher that needs to be modified is `--num_processes`, which determines the number of GPUs we will use. In this case, using the environment variable `$SLURM_GPUS`, we indicate that we want to utilize all the GPUs available on the node we have requested.
In [/slurm/submit_multinode.sh](./slurm/submit_multinode.sh) we must specify the number of nodes that will be part of the training (`--num_machines`), how many GPUs we will use in total (`--num_processes`), the [`backend`](https://pytorch.org/docs/stable/elastic/run.html#note-on-rendezvous-backend), `--main_process_ip` which will be the address the master node and the `--main_process_port`.
In [/slurm/submit_multicpu.sh](./slurm/submit_multicpu.sh) we must specify the number of nodes that will be part of the training (`--num_machines`), how many CPU processes we will use in total (`--num_processes`), the [`backend`](https://pytorch.org/docs/stable/elastic/run.html#note-on-rendezvous-backend), `--main_process_ip` which will be the address the master node and the `--main_process_port`. `mpirun_hostfile` specifies to run the job using MPIRun.
In both scripts, we run `activateEnviroment.sh` at the beginning. This script should contain the necessary instructions to initialize the environment for execution. Below, we show an example that loads the necessary libraries ([Environment modules](https://github.com/cea-hpc/modules)), activates the Python environment, and sets up various environment variables, most of them to run the scripts in offline mode in case we don't have internet connection from the cluster.
```bash
# activateEnvironment.sh
module purge
module load anaconda3/2020.02 cuda/10.2 cudnn/8.0.5 nccl/2.9.9 arrow/7.0.0 openmpi
source activate /home/nct01/nct01328/pytorch_antoni_local
export HF_HOME=/gpfs/projects/nct01/nct01328/
export HF_LOCAL_HOME=/gpfs/projects/nct01/nct01328/HF_LOCAL
export HF_DATASETS_OFFLINE=1
export TRANSFORMERS_OFFLINE=1
export PYTHONPATH=/home/nct01/nct01328/transformers-in-supercomputers:$PYTHONPATH
export GPUS_PER_NODE=4
```
## Simple Multi-GPU Hardware Launcher (using an external platform)
[multigpu_remote_launcher.py](./multigpu_remote_launcher.py) is a minimal script that demonstrates launching accelerate
on multiple remote GPUs, and with automatic hardware environment and dependency setup for reproducibility. You can
easily customize the training function used, training arguments, hyperparameters, and type of compute hardware, and then
run the script to automatically launch multi GPU training on remote hardware.
This script uses [Runhouse](https://github.com/run-house/runhouse) to launch on self-hosted hardware (e.g. in your own
cloud account or on-premise cluster) but there are other options for running remotely as well. Runhouse can be installed
with `pip install runhouse`, and you can refer to
[hardware setup](https://runhouse-docs.readthedocs-hosted.com/en/latest/api/python/cluster.html#hardware-setup)
for hardware setup instructions, or this
[Colab tutorial](https://colab.research.google.com/drive/1qVwYyLTCPYPSdz9ZX7BZl9Qm0A3j7RJe) for a more in-depth walkthrough.
## Finer Examples
While the first two scripts are extremely barebones when it comes to what you can do with accelerate, more advanced features are documented in two other locations.
### `by_feature` examples
These scripts are *individual* examples highlighting one particular feature or use-case within Accelerate. They all stem from the [nlp_example.py](./nlp_example.py) script, and any changes or modifications is denoted with a `# New Code #` comment.
Read the README.md file located in the `by_feature` folder for more information.
### `complete_*` examples
These two scripts contain *every* single feature currently available in Accelerate in one place, as one giant script.
New arguments that can be passed include:
- `checkpointing_steps`, whether the various states should be saved at the end of every `n` steps, or `"epoch"` for each epoch. States are then saved to folders named `step_{n}` or `epoch_{n}`
- `resume_from_checkpoint`, should be used if you want to resume training off of a previous call to the script and passed a `checkpointing_steps` to it.
- `with_tracking`, should be used if you want to log the training run using all available experiment trackers in your environment. Currently supported trackers include TensorBoard, Weights and Biases, and CometML.

# Release checklist
# 1. Checkout the release branch (for a patch the current release branch, for a new minor version, create one):
# git checkout -b vXX.xx-release
# The -b is only necessary for creation (so remove it when doing a patch)
# 2. Change the version in __init__.py and setup.py to the proper value.
# 3. Commit these changes with the message: "Release: v<VERSION>"
# 4. Add a tag in git to mark the release:
# git tag v<VERSION> -m 'Adds tag v<VERSION> for pypi'
# Push the tag and release commit to git: git push --tags origin vXX.xx-release
# 5. Run the following commands in the top-level directory:
# rm -rf dist
# rm -rf build
# python setup.py bdist_wheel
# python setup.py sdist
# 6. Upload the package to the pypi test server first:
# twine upload dist/* -r testpypi
# 7. Check that you can install it in a virtualenv by running:
# pip install accelerate
# pip uninstall accelerate
# pip install -i https://testpypi.python.org/pypi accelerate
# accelerate env
# accelerate test
# 8. Upload the final version to actual pypi:
# twine upload dist/* -r pypi
# 9. Add release notes to the tag in github once everything is looking hunky-dory.
# 10. Go back to the main branch and update the version in __init__.py, setup.py to the new version ".dev" and push to
# main.

A helper class to support local SGD on top of Accelerator. It simply runs a given number of updates independently

this is a simple implementation that cannot support scenarios such as model parallelism.

# candle-starcoder: code generation model
[StarCoder/BigCode](https://huggingface.co/bigcode/starcoderbase-1b) is a LLM
model specialized to code generation. The initial model was trained on 80
programming languages.
## Running some example
```bash
cargo run --example bigcode --release -- --prompt "fn fact(n: u64) -> u64 "
> fn fact(n: u64) -> u64 {
> if n == 0 {
> 1
> } else {
> n * fact(n - 1)
> }
> }

# candle-dinov2
[Depth Anything V2] is a model for Monocular Depth Estimation (MDE, i.e. just using a single image) which
builds on the [DINOv2](https://github.com/facebookresearch/dinov2) vision transformer.
This example first instantiates the DINOv2 model and then proceeds to create DepthAnythingV2 and run it.
## Running an example with color map and CUDA
```bash
cargo run --features cuda,depth_anything_v2 --package candle-examples --example depth_anything_v2 -- --color-map --image candle-examples/examples/yolo-v8/assets/bike.jpg
```

# hiera
[Hiera: A Hierarchical Vision Transformer without the Bells-and-Whistles](https://arxiv.org/abs/2306.00989)
This candle implementation uses pre-trained Hiera models from timm for inference.
The classification head has been trained on the ImageNet dataset and returns the probabilities for the top-5 classes.
## Running an example

# Chat UI
**Find the docs at [hf.co/docs/chat-ui](https://huggingface.co/docs/chat-ui/index).**
A chat interface using open source models, eg OpenAssistant or Llama. It is a SvelteKit app and it powers the [HuggingChat app on hf.co/chat](https://huggingface.co/chat).

8. [Deploying to a HF Space](#deploying-to-a-hf-space)
9. [Building](#building)
## Quickstart
You can quickly start a locally running chat-ui & LLM text-generation server thanks to chat-ui's [llama.cpp server support](https://huggingface.co/docs/chat-ui/configuration/models/providers/llamacpp).
**Step 1 (Start llama.cpp server):**
Install llama.cpp w/ brew (for Mac):
```bash
# install llama.cpp
brew install llama.cpp
```
or [build directly from the source](https://github.com/ggerganov/llama.cpp/blob/master/docs/build.md) for your target device:
```
git clone https://github.com/ggerganov/llama.cpp && cd llama.cpp && make
```
Next, start the server with the [LLM of your choice](https://huggingface.co/models?library=gguf):
```bash
# start llama.cpp server (using hf.co/microsoft/Phi-3-mini-4k-instruct-gguf as an example)
llama-server --hf-repo microsoft/Phi-3-mini-4k-instruct-gguf --hf-file Phi-3-mini-4k-instruct-q4.gguf -c 4096
```
A local LLaMA.cpp HTTP Server will start on `http://localhost:8080`. Read more [here](https://huggingface.co/docs/chat-ui/configuration/models/providers/llamacpp).
**Step 2 (tell chat-ui to use local llama.cpp server):**
Add the following to your `.env.local`:
```ini
MODELS=`[
{
"name": "Local microsoft/Phi-3-mini-4k-instruct-gguf",
"tokenizer": "microsoft/Phi-3-mini-4k-instruct-gguf",
"preprompt": "",
"chatPromptTemplate": "<s>{{preprompt}}{{#each messages}}{{#ifUser}}<|user|>\n{{content}}<|end|>\n<|assistant|>\n{{/ifUser}}{{#ifAssistant}}{{content}}<|end|>\n{{/ifAssistant}}{{/each}}",
"parameters": {
"stop": ["<|end|>", "<|endoftext|>", "<|assistant|>"],
"temperature": 0.7,
"max_new_tokens": 1024,
"truncate": 3071
},
"endpoints": [{
"type" : "llamacpp",
"baseURL": "http://localhost:8080"
}],
},
]`
```
Read more [here](https://huggingface.co/docs/chat-ui/configuration/models/providers/llamacpp).
**Step 3 (make sure you have MongoDb running locally):**
```bash
docker run -d -p 27017:27017 --name mongo-chatui mongo:latest
```
Read more [here](#database).
**Step 4 (start chat-ui):**
```bash
git clone https://github.com/huggingface/chat-ui
cd chat-ui
npm install
npm run dev -- --open
```
Read more [here](#launch).

## No Setup Deploy
If you don't want to configure, setup, and launch your own Chat UI yourself, you can use this option as a fast deploy alternative.
You can deploy your own customized Chat UI instance with any supported [LLM](https://huggingface.co/models?pipeline_tag=text-generation&sort=trending) of your choice on [Hugging Face Spaces](https://huggingface.co/spaces). To do so, use the chat-ui template [available here](https://huggingface.co/new-space?template=huggingchat/chat-ui-template).
Set `HF_TOKEN` in [Space secrets](https://huggingface.co/docs/hub/spaces-overview#managing-secrets-and-environment-variables) to deploy a model with gated access or a model in a private repository. It's also compatible with [Inference for PROs](https://huggingface.co/blog/inference-pro) curated list of powerful models with higher rate limits. Make sure to create your personal token first in your [User Access Tokens settings](https://huggingface.co/settings/tokens).
Read the full tutorial [here](https://huggingface.co/docs/hub/spaces-sdks-docker-chatui#chatui-on-spaces).
## Setup
The default config for Chat UI is stored in the `.env` file. You will need to override some values to get Chat UI to run locally. This is done in `.env.local`.
Start by creating a `.env.local` file in the root of the repository. The bare minimum config you need to get Chat UI to run locally is the following:
```env
MONGODB_URL=<the URL to your MongoDB instance>
HF_TOKEN=<your access token>
```

The chat history is stored in a MongoDB instance, and having a DB instance available is needed for Chat UI to work.
You can use a local MongoDB instance. The easiest way is to spin one up using docker:
```bash
docker run -d -p 27017:27017 --name mongo-chatui mongo:latest
```
In which case the url of your DB will be `MONGODB_URL=mongodb://localhost:27017`.
Alternatively, you can use a [free MongoDB Atlas](https://www.mongodb.com/pricing) instance for this, Chat UI should fit comfortably within their free tier. After which you can set the `MONGODB_URL` variable in `.env.local` to match your instance.
### Hugging Face Access Token
If you use a remote inference endpoint, you will need a Hugging Face access token to run Chat UI locally. You can get one from [your Hugging Face profile](https://huggingface.co/settings/tokens).
## Launch
After you're done with the `.env.local` file you can run Chat UI locally with:
```bash
npm install
npm run dev
```
## Web Search
Chat UI features a powerful Web Search feature. It works by:
1. Generating an appropriate search query from the user prompt.
2. Performing web search and extracting content from webpages.
3. Creating embeddings from texts using a text embedding model.
4. From these embeddings, find the ones that are closest to the user query using a vector similarity search. Specifically, we use `inner product` distance.
5. Get the corresponding texts to those closest embeddings and perform [Retrieval-Augmented Generation](https://huggingface.co/papers/2005.11401) (i.e. expand user prompt by adding those texts so that an LLM can use this information).
## Text Embedding Models
By default (for backward compatibility), when `TEXT_EMBEDDING_MODELS` environment variable is not defined, [transformers.js](https://huggingface.co/docs/transformers.js) embedding models will be used for embedding tasks, specifically, [Xenova/gte-small](https://huggingface.co/Xenova/gte-small) model.
You can customize the embedding model by setting `TEXT_EMBEDDING_MODELS` in your `.env.local` file. For example:
```env
TEXT_EMBEDDING_MODELS = `[
{
"name": "Xenova/gte-small",
"displayName": "Xenova/gte-small",
"description": "locally running embedding",
"chunkCharLength": 512,
"endpoints": [
{"type": "transformersjs"}
]
},
{
"name": "intfloat/e5-base-v2",
"displayName": "intfloat/e5-base-v2",
"description": "hosted embedding model",
"chunkCharLength": 768,
"preQuery": "query: ", # See https://huggingface.co/intfloat/e5-base-v2#faq
"prePassage": "passage: ", # See https://huggingface.co/intfloat/e5-base-v2#faq
"endpoints": [
{
"type": "tei",
"url": "http://127.0.0.1:8080/",
"authorization": "TOKEN_TYPE TOKEN" // optional authorization field. Example: "Basic VVNFUjpQQVNT"
}
]
}
]`
```
The required fields are `name`, `chunkCharLength` and `endpoints`.
Supported text embedding backends are: [`transformers.js`](https://huggingface.co/docs/transformers.js), [`TEI`](https://github.com/huggingface/text-embeddings-inference) and [`OpenAI`](https://platform.openai.com/docs/guides/embeddings). `transformers.js` models run locally as part of `chat-ui`, whereas `TEI` models run in a different environment & accessed through an API endpoint. `openai` models are accessed through the [OpenAI API](https://platform.openai.com/docs/guides/embeddings).
When more than one embedding models are supplied in `.env.local` file, the first will be used by default, and the others will only be used on LLM's which configured `embeddingModel` to the name of the model.
## Extra parameters
### OpenID connect
The login feature is disabled by default and users are attributed a unique ID based on their browser. But if you want to use OpenID to authenticate your users, you can add the following to your `.env.local` file:
```env
OPENID_CONFIG=`{
PROVIDER_URL: "<your OIDC issuer>",
CLIENT_ID: "<your OIDC client ID>",
CLIENT_SECRET: "<your OIDC client secret>",
SCOPES: "openid profile",
TOLERANCE: // optional
RESOURCE: // optional
}`
```
These variables will enable the openID sign-in modal for users.
### Trusted header authentication
You can set the env variable `TRUSTED_EMAIL_HEADER` to point to the header that contains the user's email address. This will allow you to authenticate users from the header. This setup is usually combined with a proxy that will be in front of chat-ui and will handle the auth and set the header.
> [!WARNING]
> Make sure to only allow requests to chat-ui through your proxy which handles authentication, otherwise users could authenticate as anyone by setting the header manually! Only set this up if you understand the implications and know how to do it correctly.
Here is a list of header names for common auth providers:
- Tailscale Serve: `Tailscale-User-Login`
- Cloudflare Access: `Cf-Access-Authenticated-User-Email`
- oauth2-proxy: `X-Forwarded-Email`
### Theming
You can use a few environment variables to customize the look and feel of chat-ui. These are by default:
```env
PUBLIC_APP_NAME=ChatUI
PUBLIC_APP_ASSETS=chatui
PUBLIC_APP_COLOR=blue
PUBLIC_APP_DESCRIPTION="Making the community's best AI chat models available to everyone."
PUBLIC_APP_DATA_SHARING=
PUBLIC_APP_DISCLAIMER=
```
- `PUBLIC_APP_NAME` The name used as a title throughout the app.
- `PUBLIC_APP_ASSETS` Is used to find logos & favicons in `static/$PUBLIC_APP_ASSETS`, current options are `chatui` and `huggingchat`.
- `PUBLIC_APP_COLOR` Can be any of the [tailwind colors](https://tailwindcss.com/docs/customizing-colors#default-color-palette).
- `PUBLIC_APP_DATA_SHARING` Can be set to 1 to add a toggle in the user settings that lets your users opt-in to data sharing with models creator.
- `PUBLIC_APP_DISCLAIMER` If set to 1, we show a disclaimer about generated outputs on login.
### Web Search config
You can enable the web search through an API by adding `YDC_API_KEY` ([docs.you.com](https://docs.you.com)) or `SERPER_API_KEY` ([serper.dev](https://serper.dev/)) or `SERPAPI_KEY` ([serpapi.com](https://serpapi.com/)) or `SERPSTACK_API_KEY` ([serpstack.com](https://serpstack.com/)) or `SEARCHAPI_KEY` ([searchapi.io](https://www.searchapi.io/)) to your `.env.local`.
You can also simply enable the local google websearch by setting `USE_LOCAL_WEBSEARCH=true` in your `.env.local` or specify a SearXNG instance by adding the query URL to `SEARXNG_QUERY_URL`.
You can enable javascript when parsing webpages to improve compatibility with `WEBSEARCH_JAVASCRIPT=true` at the cost of increased CPU usage. You'll want at least 4 cores when enabling.
### Custom models
You can customize the parameters passed to the model or even use a new model by updating the `MODELS` variable in your `.env.local`. The default one can be found in `.env` and looks like this :
```env
MODELS=`[
{
"name": "mistralai/Mistral-7B-Instruct-v0.2",
"displayName": "mistralai/Mistral-7B-Instruct-v0.2",
"description": "Mistral 7B is a new Apache 2.0 model, released by Mistral AI that outperforms Llama2 13B in benchmarks.",
"websiteUrl": "https://mistral.ai/news/announcing-mistral-7b/",
"preprompt": "",
"chatPromptTemplate" : "<s>{{#each messages}}{{#ifUser}}[INST] {{#if @first}}{{#if @root.preprompt}}{{@root.preprompt}}\n{{/if}}{{/if}}{{content}} [/INST]{{/ifUser}}{{#ifAssistant}}{{content}}</s>{{/ifAssistant}}{{/each}}",
"parameters": {
"temperature": 0.3,
"top_p": 0.95,
"repetition_penalty": 1.2,
"top_k": 50,
"truncate": 3072,
"max_new_tokens": 1024,
"stop": ["</s>"]
},
"promptExamples": [
{
"title": "Write an email from bullet list",
"prompt": "As a restaurant owner, write a professional email to the supplier to get these products every week: \n\n- Wine (x10)\n- Eggs (x24)\n- Bread (x12)"
}, {
"title": "Code a snake game",
"prompt": "Code a basic snake game in python, give explanations for each step."
}, {
"title": "Assist in a task",
"prompt": "How do I make a delicious lemon cheesecake?"
}
]
}
]`
```
You can change things like the parameters, or customize the preprompt to better suit your needs. You can also add more models by adding more objects to the array, with different preprompts for example.
#### chatPromptTemplate
When querying the model for a chat response, the `chatPromptTemplate` template is used. `messages` is an array of chat messages, it has the format `[{ content: string }, ...]`. To identify if a message is a user message or an assistant message the `ifUser` and `ifAssistant` block helpers can be used.
The following is the default `chatPromptTemplate`, although newlines and indentiation have been added for readability. You can find the prompts used in production for HuggingChat [here](https://github.com/huggingface/chat-ui/blob/main/PROMPTS.md).
```prompt
{{preprompt}}
{{#each messages}}
{{#ifUser}}{{@root.userMessageToken}}{{content}}{{@root.userMessageEndToken}}{{/ifUser}}
{{#ifAssistant}}{{@root.assistantMessageToken}}{{content}}{{@root.assistantMessageEndToken}}{{/ifAssistant}}
{{/each}}
{{assistantMessageToken}}
```
#### Multi modal model
We currently support [IDEFICS](https://huggingface.co/blog/idefics) (hosted on TGI), OpenAI and Claude 3 as multimodal models. You can enable it by setting `multimodal: true` in your `MODELS` configuration. For IDEFICS, you must have a [PRO HF Api token](https://huggingface.co/settings/tokens). For OpenAI, see the [OpenAI section](#OpenAI). For Anthropic, see the [Anthropic section](#anthropic).
```env
{
"name": "HuggingFaceM4/idefics-80b-instruct",
"multimodal" : true,
"description": "IDEFICS is the new multimodal model by Hugging Face.",
"preprompt": "",
"chatPromptTemplate" : "{{#each messages}}{{#ifUser}}User: {{content}}{{/ifUser}}<end_of_utterance>\nAssistant: {{#ifAssistant}}{{content}}\n{{/ifAssistant}}{{/each}}",
"parameters": {
"temperature": 0.1,
"top_p": 0.95,
"repetition_penalty": 1.2,
"top_k": 12,
"truncate": 1000,
"max_new_tokens": 1024,
"stop": ["<end_of_utterance>", "User:", "\nUser:"]
}
}
```
#### Running your own models using a custom endpoint
If you want to, instead of hitting models on the Hugging Face Inference API, you can run your own models locally.
A good option is to hit a [text-generation-inference](https://github.com/huggingface/text-generation-inference) endpoint. This is what is done in the official [Chat UI Spaces Docker template](https://huggingface.co/new-space?template=huggingchat/chat-ui-template) for instance: both this app and a text-generation-inference server run inside the same container.
To do this, you can add your own endpoints to the `MODELS` variable in `.env.local`, by adding an `"endpoints"` key for each model in `MODELS`.
```env
{
// rest of the model config here
"endpoints": [{
"type" : "tgi",
"url": "https://HOST:PORT",
}]
}
```
If `endpoints` are left unspecified, ChatUI will look for the model on the hosted Hugging Face inference API using the model name.
##### OpenAI API compatible models
Chat UI can be used with any API server that supports OpenAI API compatibility, for example [text-generation-webui](https://github.com/oobabooga/text-generation-webui/tree/main/extensions/openai), [LocalAI](https://github.com/go-skynet/LocalAI), [FastChat](https://github.com/lm-sys/FastChat/blob/main/docs/openai_api.md), [llama-cpp-python](https://github.com/abetlen/llama-cpp-python), and [ialacol](https://github.com/chenhunghan/ialacol) and [vllm](https://docs.vllm.ai/en/latest/serving/openai_compatible_server.html).
The following example config makes Chat UI works with [text-generation-webui](https://github.com/oobabooga/text-generation-webui/tree/main/extensions/openai), the `endpoint.baseUrl` is the url of the OpenAI API compatible server, this overrides the baseUrl to be used by OpenAI instance. The `endpoint.completion` determine which endpoint to be used, default is `chat_completions` which uses `v1/chat/completions`, change to `endpoint.completion` to `completions` to use the `v1/completions` endpoint.
Parameters not supported by OpenAI (e.g., top_k, repetition_penalty, etc.) must be set in the extraBody of endpoints. Be aware that setting them in parameters will cause them to be omitted.
```
MODELS=`[
{
"name": "text-generation-webui",
"id": "text-generation-webui",
"parameters": {
"temperature": 0.9,
"top_p": 0.95,
"max_new_tokens": 1024,
"stop": []
},
"endpoints": [{
"type" : "openai",
"baseURL": "http://localhost:8000/v1",
"extraBody": {
"repetition_penalty": 1.2,
"top_k": 50,
"truncate": 1000
}
}]
}
]`
```
The `openai` type includes official OpenAI models. You can add, for example, GPT4/GPT3.5 as a "openai" model:
```
OPENAI_API_KEY=#your openai api key here
MODELS=`[{
"name": "gpt-4",
"displayName": "GPT 4",
"endpoints" : [{
"type": "openai"
}]
},
{
"name": "gpt-3.5-turbo",
"displayName": "GPT 3.5 Turbo",
"endpoints" : [{
"type": "openai"
}]
}]`
```
You may also consume any model provider that provides compatible OpenAI API endpoint. For example, you may self-host [Portkey](https://github.com/Portkey-AI/gateway) gateway and experiment with Claude or GPTs offered by Azure OpenAI. Example for Claude from Anthropic:
```
MODELS=`[{
"name": "claude-2.1",
"displayName": "Claude 2.1",
"description": "Anthropic has been founded by former OpenAI researchers...",
"parameters": {
"temperature": 0.5,
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "openai",
"baseURL": "https://gateway.example.com/v1",
"defaultHeaders": {
"x-portkey-config": '{"provider":"anthropic","api_key":"sk-ant-abc...xyz"}'
}
}
]
}]`
```
Example for GPT 4 deployed on Azure OpenAI:
```
MODELS=`[{
"id": "gpt-4-1106-preview",
"name": "gpt-4-1106-preview",
"displayName": "gpt-4-1106-preview",
"parameters": {
"temperature": 0.5,
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "openai",
"baseURL": "https://{resource-name}.openai.azure.com/openai/deployments/{deployment-id}",
"defaultHeaders": {
"api-key": "{api-key}"
},
"defaultQuery": {
"api-version": "2023-05-15"
}
}
]
}]`
```
Or try Mistral from [Deepinfra](https://deepinfra.com/mistralai/Mistral-7B-Instruct-v0.1/api?example=openai-http):
> Note, apiKey can either be set custom per endpoint, or globally using `OPENAI_API_KEY` variable.
```
MODELS=`[{
"name": "mistral-7b",
"displayName": "Mistral 7B",
"description": "A 7B dense Transformer, fast-deployed and easily customisable. Small, yet powerful for a variety of use cases. Supports English and code, and a 8k context window.",
"parameters": {
"temperature": 0.5,
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "openai",
"baseURL": "https://api.deepinfra.com/v1/openai",
"apiKey": "abc...xyz"
}
]
}]`
```
##### Llama.cpp API server
chat-ui also supports the llama.cpp API server directly without the need for an adapter. You can do this using the `llamacpp` endpoint type.
If you want to run Chat UI with llama.cpp, you can do the following, using [microsoft/Phi-3-mini-4k-instruct-gguf](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf) as an example model:
```bash
# install llama.cpp
brew install llama.cpp
# start llama.cpp server
llama-server --hf-repo microsoft/Phi-3-mini-4k-instruct-gguf --hf-file Phi-3-mini-4k-instruct-q4.gguf -c 4096
```
```env
MODELS=`[
{
"name": "Local Zephyr",
"chatPromptTemplate": "<|system|>\n{{preprompt}}</s>\n{{#each messages}}{{#ifUser}}<|user|>\n{{content}}</s>\n<|assistant|>\n{{/ifUser}}{{#ifAssistant}}{{content}}</s>\n{{/ifAssistant}}{{/each}}",
"parameters": {
"temperature": 0.1,
"top_p": 0.95,
"repetition_penalty": 1.2,
"top_k": 50,
"truncate": 1000,
"max_new_tokens": 2048,
"stop": ["</s>"]
},
"endpoints": [
{
"url": "http://127.0.0.1:8080",
"type": "llamacpp"
}
]
}
]`
```
Start chat-ui with `npm run dev` and you should be able to chat with Zephyr locally.
#### Ollama
We also support the Ollama inference server. Spin up a model with
```cli
ollama run mistral
```
Then specify the endpoints like so:
```env
MODELS=`[
{
"name": "Ollama Mistral",
"chatPromptTemplate": "<s>{{#each messages}}{{#ifUser}}[INST] {{#if @first}}{{#if @root.preprompt}}{{@root.preprompt}}\n{{/if}}{{/if}} {{content}} [/INST]{{/ifUser}}{{#ifAssistant}}{{content}}</s> {{/ifAssistant}}{{/each}}",
"parameters": {
"temperature": 0.1,
"top_p": 0.95,
"repetition_penalty": 1.2,
"top_k": 50,
"truncate": 3072,
"max_new_tokens": 1024,
"stop": ["</s>"]
},
"endpoints": [
{
"type": "ollama",
"url" : "http://127.0.0.1:11434",
"ollamaName" : "mistral"
}
]
}
]`
```
#### Anthropic
We also support Anthropic models (including multimodal ones via `multmodal: true`) through the official SDK. You may provide your API key via the `ANTHROPIC_API_KEY` env variable, or alternatively, through the `endpoints.apiKey` as per the following example.
```
MODELS=`[
{
"name": "claude-3-haiku-20240307",
"displayName": "Claude 3 Haiku",
"description": "Fastest and most compact model for near-instant responsiveness",
"multimodal": true,
"parameters": {
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "anthropic",
// optionals
"apiKey": "sk-ant-...",
"baseURL": "https://api.anthropic.com",
"defaultHeaders": {},
"defaultQuery": {}
}
]
},
{
"name": "claude-3-sonnet-20240229",
"displayName": "Claude 3 Sonnet",
"description": "Ideal balance of intelligence and speed",
"multimodal": true,
"parameters": {
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "anthropic",
// optionals
"apiKey": "sk-ant-...",
"baseURL": "https://api.anthropic.com",
"defaultHeaders": {},
"defaultQuery": {}
}
]
},
{
"name": "claude-3-opus-20240229",
"displayName": "Claude 3 Opus",
"description": "Most powerful model for highly complex tasks",
"multimodal": true,
"parameters": {
"max_new_tokens": 4096
},
"endpoints": [
{
"type": "anthropic",
// optionals
"apiKey": "sk-ant-...",
"baseURL": "https://api.anthropic.com",
"defaultHeaders": {},
"defaultQuery": {}
}
]
}
]`
```
We also support using Anthropic models running on Vertex AI. Authentication is done using Google Application Default Credentials. Project ID can be provided through the `endpoints.projectId` as per the following example:
```
MODELS=`[
{
"name": "claude-3-sonnet@20240229",
"displayName": "Claude 3 Sonnet",
"description": "Ideal balance of intelligence and speed",
"multimodal": true,
"parameters": {
"max_new_tokens": 4096,
},
"endpoints": [
{
"type": "anthropic-vertex",
"region": "us-central1",
"projectId": "gcp-project-id",
// optionals
"defaultHeaders": {},
"defaultQuery": {}
}
]
},
{
"name": "claude-3-haiku@20240307",
"displayName": "Claude 3 Haiku",
"description": "Fastest, most compact model for near-instant responsiveness",
"multimodal": true,
"parameters": {
"max_new_tokens": 4096
},
"endpoints": [
{
"type": "anthropic-vertex",
"region": "us-central1",
"projectId": "gcp-project-id",
// optionals
"defaultHeaders": {},
"defaultQuery": {}
}
]
}
]`
```
#### Amazon
You can also specify your Amazon SageMaker instance as an endpoint for chat-ui. The config goes like this:
```env
"endpoints": [
{
"type" : "aws",
"service" : "sagemaker"
"url": "",
"accessKey": "",
"secretKey" : "",
"sessionToken": "",
"region": "",
"weight": 1
}
]
```
You can also set `"service" : "lambda"` to use a lambda instance.
You can get the `accessKey` and `secretKey` from your AWS user, under programmatic access.
#### Cloudflare Workers AI
You can also use Cloudflare Workers AI to run your own models with serverless inference.
You will need to have a Cloudflare account, then get your [account ID](https://developers.cloudflare.com/fundamentals/setup/find-account-and-zone-ids/) as well as your [API token](https://developers.cloudflare.com/workers-ai/get-started/rest-api/#1-get-an-api-token) for Workers AI.
You can either specify them directly in your `.env.local` using the `CLOUDFLARE_ACCOUNT_ID` and `CLOUDFLARE_API_TOKEN` variables, or you can set them directly in the endpoint config.
You can find the list of models available on Cloudflare [here](https://developers.cloudflare.com/workers-ai/models/#text-generation).
```env
{
"name" : "nousresearch/hermes-2-pro-mistral-7b",
"tokenizer": "nousresearch/hermes-2-pro-mistral-7b",
"parameters": {
"stop": ["<|im_end|>"]
},
"endpoints" : [
{
"type" : "cloudflare"
<!-- optionally specify these
"accountId": "your-account-id",
"authToken": "your-api-token"
-->
}
]
}
```
#### Cohere
You can also use Cohere to run their models directly from chat-ui. You will need to have a Cohere account, then get your [API token](https://dashboard.cohere.com/api-keys). You can either specify it directly in your `.env.local` using the `COHERE_API_TOKEN` variable, or you can set it in the endpoint config.
Here is an example of a Cohere model config. You can set which model you want to use by setting the `id` field to the model name.
```env
{
"name" : "CohereForAI/c4ai-command-r-v01",
"id": "command-r",
"description": "C4AI Command-R is a research release of a 35 billion parameter highly performant generative model",
"endpoints": [
{
"type": "cohere",
<!-- optionally specify these, or use COHERE_API_TOKEN
"apiKey": "your-api-token"
-->
}
]
}
```
##### Google Vertex models
Chat UI can connect to the google Vertex API endpoints ([List of supported models](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/models)).
To enable:
1. [Select](https://console.cloud.google.com/project) or [create](https://cloud.google.com/resource-manager/docs/creating-managing-projects#creating_a_project) a Google Cloud project.
1. [Enable billing for your project](https://cloud.google.com/billing/docs/how-to/modify-project).
1. [Enable the Vertex AI API](https://console.cloud.google.com/flows/enableapi?apiid=aiplatform.googleapis.com).
1. [Set up authentication with a service account](https://cloud.google.com/docs/authentication/getting-started)
so you can access the API from your local workstation.
The service account credentials file can be imported as an environmental variable:
```env
GOOGLE_APPLICATION_CREDENTIALS = clientid.json
```
Make sure your docker container has access to the file and the variable is correctly set.
Afterwards Google Vertex endpoints can be configured as following:
```
MODELS=`[
//...
{
"name": "gemini-1.5-pro",
"displayName": "Vertex Gemini Pro 1.5",
"endpoints" : [{
"type": "vertex",
"project": "abc-xyz",
"location": "europe-west3",
"model": "gemini-1.5-pro-preview-0409", // model-name
// Optional
"safetyThreshold": "BLOCK_MEDIUM_AND_ABOVE",
"apiEndpoint": "", // alternative api endpoint url,
// Optional
"tools": [{
"googleSearchRetrieval": {
"disableAttribution": true
}
}]
}]
},
]`
```
##### LangServe
LangChain applications that are deployed using LangServe can be called with the following config:
```
MODELS=`[
//...
{
"name": "summarization-chain", //model-name
"endpoints" : [{
"type": "langserve",
"url" : "http://127.0.0.1:8100",
}]
},
]`
```
### Custom endpoint authorization
#### Basic and Bearer
Custom endpoints may require authorization, depending on how you configure them. Authentication will usually be set either with `Basic` or `Bearer`.
For `Basic` we will need to generate a base64 encoding of the username and password.
`echo -n "USER:PASS" | base64`
> VVNFUjpQQVNT
For `Bearer` you can use a token, which can be grabbed from [here](https://huggingface.co/settings/tokens).
You can then add the generated information and the `authorization` parameter to your `.env.local`.
```env
"endpoints": [
{
"url": "https://HOST:PORT",
"authorization": "Basic VVNFUjpQQVNT",
}
]
```
Please note that if `HF_TOKEN` is also set or not empty, it will take precedence.
#### Models hosted on multiple custom endpoints
If the model being hosted will be available on multiple servers/instances add the `weight` parameter to your `.env.local`. The `weight` will be used to determine the probability of requesting a particular endpoint.
```env
"endpoints": [
{
"url": "https://HOST:PORT",
"weight": 1
},
{
"url": "https://HOST:PORT",
"weight": 2
}
...
]
```
#### Client Certificate Authentication (mTLS)
Custom endpoints may require client certificate authentication, depending on how you configure them. To enable mTLS between Chat UI and your custom endpoint, you will need to set the `USE_CLIENT_CERTIFICATE` to `true`, and add the `CERT_PATH` and `KEY_PATH` parameters to your `.env.local`. These parameters should point to the location of the certificate and key files on your local machine. The certificate and key files should be in PEM format. The key file can be encrypted with a passphrase, in which case you will also need to add the `CLIENT_KEY_PASSWORD` parameter to your `.env.local`.
If you're using a certificate signed by a private CA, you will also need to add the `CA_PATH` parameter to your `.env.local`. This parameter should point to the location of the CA certificate file on your local machine.
If you're using a self-signed certificate, e.g. for testing or development purposes, you can set the `REJECT_UNAUTHORIZED` parameter to `false` in your `.env.local`. This will disable certificate validation, and allow Chat UI to connect to your custom endpoint.
#### Specific Embedding Model
A model can use any of the embedding models defined in `.env.local`, (currently used when web searching),
by default it will use the first embedding model, but it can be changed with the field `embeddingModel`:
```env
TEXT_EMBEDDING_MODELS = `[
{
"name": "Xenova/gte-small",
"chunkCharLength": 512,
"endpoints": [
{"type": "transformersjs"}
]
},
{
"name": "intfloat/e5-base-v2",
"chunkCharLength": 768,
"endpoints": [
{"type": "tei", "url": "http://127.0.0.1:8080/", "authorization": "Basic VVNFUjpQQVNT"},
{"type": "tei", "url": "http://127.0.0.1:8081/"}
]
}
]`
MODELS=`[
{
"name": "Ollama Mistral",
"chatPromptTemplate": "...",
"embeddingModel": "intfloat/e5-base-v2"
"parameters": {
...
},
"endpoints": [
...
]
}
]`
```
## Common issues
### 403๏ผYou don't have access to this conversation
Most likely you are running chat-ui over HTTP. The recommended option is to setup something like NGINX to handle HTTPS and proxy the requests to chat-ui. If you really need to run over HTTP you can add `ALLOW_INSECURE_COOKIES=true` to your `.env.local`.
Make sure to set your `PUBLIC_ORIGIN` in your `.env.local` to the correct URL as well.
## Deploying to a HF Space
Create a `DOTENV_LOCAL` secret to your HF space with the content of your .env.local, and they will be picked up automatically when you run.
## Building
To create a production version of your app:
```bash
npm run build
```
You can preview the production build with `npm run preview`.
> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
## Config changes for HuggingChat
The config file for HuggingChat is stored in the `chart/env/prod.yaml` file. It is the source of truth for the environment variables used for our CI/CD pipeline. For HuggingChat, as we need to customize the app color, as well as the base path, we build a custom docker image. You can find the workflow here.
> [!TIP]
> If you want to make changes to the model config used in production for HuggingChat, you should do so against `chart/env/prod.yaml`.
### Running a copy of HuggingChat locally
If you want to run an exact copy of HuggingChat locally, you will need to do the following first:
1. Create an [OAuth App on the hub](https://huggingface.co/settings/applications/new) with `openid profile email` permissions. Make sure to set the callback URL to something like `http://localhost:5173/chat/login/callback` which matches the right path for your local instance.
2. Create a [HF Token](https://huggingface.co/settings/tokens) with your Hugging Face account. You will need a Pro account to be able to access some of the larger models available through HuggingChat.
3. Create a free account with [serper.dev](https://serper.dev/) (you will get 2500 free search queries)
4. Run an instance of mongoDB, however you want. (Local or remote)
You can then create a new `.env.SECRET_CONFIG` file with the following content
```env
MONGODB_URL=<link to your mongo DB from step 4>
HF_TOKEN=<your HF token from step 2>
OPENID_CONFIG=`{
PROVIDER_URL: "https://huggingface.co",
CLIENT_ID: "<your client ID from step 1>",
CLIENT_SECRET: "<your client secret from step 1>",
}`
SERPER_API_KEY=<your serper API key from step 3>
MESSAGES_BEFORE_LOGIN=<can be any numerical value, or set to 0 to require login>
```
You can then run `npm run updateLocalEnv` in the root of chat-ui. This will create a `.env.local` file which combines the `chart/env/prod.yaml` and the `.env.SECRET_CONFIG` file. You can then run `npm run dev` to start your local instance of HuggingChat.
### Populate database
> [!WARNING]
> The `MONGODB_URL` used for this script will be fetched from `.env.local`. Make sure it's correct! The command runs directly on the database.
You can populate the database using faker data using the `populate` script:
```bash
npm run populate <flags here>
```
At least one flag must be specified, the following flags are available:
- `reset` - resets the database
- `all` - populates all tables
- `users` - populates the users table
- `settings` - populates the settings table for existing users
- `assistants` - populates the assistants table for existing users
- `conversations` - populates the conversations table for existing users
For example, you could use it like so:
```bash
npm run populate reset
```
to clear out the database. Then login in the app to create your user and run the following command:
```bash
npm run populate users settings assistants conversations
```
to populate the database with fake data, including fake conversations and assistants for your user.

# Metrics
The server can expose prometheus metrics on port `5565` but is off by default. You may enable the metrics server with `METRICS_ENABLED=true` and change the port with `METRICS_PORT=1234`.
<Tip>
In development with `npm run dev`, the metrics server does not shutdown gracefully due to Sveltekit not providing hooks for restart. It's recommended to disable the metrics server in this case.

# Theming
You can use a few environment variables to customize the look and feel of Chat UI. These are by default:
```ini
PUBLIC_APP_NAME=ChatUI
PUBLIC_APP_ASSETS=chatui
PUBLIC_APP_COLOR=blue
PUBLIC_APP_DESCRIPTION="Making the community's best AI chat models available to everyone."
PUBLIC_APP_DATA_SHARING=
PUBLIC_APP_DISCLAIMER=
```
- `PUBLIC_APP_NAME` The name used as a title throughout the app.
- `PUBLIC_APP_ASSETS` Is used to find logos & favicons in `static/$PUBLIC_APP_ASSETS`, current options are `chatui` and `huggingchat`.
- `PUBLIC_APP_COLOR` Can be any of the [tailwind colors](https://tailwindcss.com/docs/customizing-colors#default-color-palette).
- `PUBLIC_APP_DATA_SHARING` Can be set to 1 to add a toggle in the user settings that lets your users opt-in to data sharing with models creator.
- `PUBLIC_APP_DISCLAIMER` If set to 1, we show a disclaimer about generated outputs on login.

# Know your dataset
There are two types of dataset objects, a regular [`Dataset`] and then an โจ [`IterableDataset`] โจ. A [`Dataset`] provides fast random access to the rows, and memory-mapping so that loading even large datasets only uses a relatively small amount of device memory. But for really, really big datasets that won't even fit on disk or in memory, an [`IterableDataset`] allows you to access and use the dataset without waiting for it to download completely!
This tutorial will show you how to load and access a [`Dataset`] and an [`IterableDataset`].
## Dataset
When you load a dataset split, you'll get a [`Dataset`] object. You can do many things with a [`Dataset`] object, which is why it's important to learn how to manipulate and interact with the data stored inside.
This tutorial uses the [rotten_tomatoes](https://huggingface.co/datasets/rotten_tomatoes) dataset, but feel free to load any dataset you'd like and follow along!
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("rotten_tomatoes", split="train")
```
### Indexing
A [`Dataset`] contains columns of data, and each column can be a different type of data. The *index*, or axis label, is used to access examples from the dataset. For example, indexing by the row returns a dictionary of an example from the dataset:
```py
# Get the first row in the dataset
>>> dataset[0]
{'label': 1,
'text': 'the rock is destined to be the 21st century\'s new " conan " and that he\'s going to make a splash even greater than arnold schwarzenegger , jean-claud van damme or steven segal .'}
```
Use the `-` operator to start from the end of the dataset:
```py
# Get the last row in the dataset
>>> dataset[-1]
{'label': 0,
'text': 'things really get weird , though not particularly scary : the movie is all portent and no content .'}
```
Indexing by the column name returns a list of all the values in the column:
```py
>>> dataset["text"]
['the rock is destined to be the 21st century\'s new " conan " and that he\'s going to make a splash even greater than arnold schwarzenegger , jean-claud van damme or steven segal .',
'the gorgeously elaborate continuation of " the lord of the rings " trilogy is so huge that a column of words cannot adequately describe co-writer/director peter jackson\'s expanded vision of j . r . r . tolkien\'s middle-earth .',
'effective but too-tepid biopic',
...,
'things really get weird , though not particularly scary : the movie is all portent and no content .']
```
You can combine row and column name indexing to return a specific value at a position:
```py
>>> dataset[0]["text"]
'the rock is destined to be the 21st century\'s new " conan " and that he\'s going to make a splash even greater than arnold schwarzenegger , jean-claud van damme or steven segal .'
```
But it is important to remember that indexing order matters, especially when working with large audio and image datasets. Indexing by the column name returns all the values in the column first, then loads the value at that position. For large datasets, it may be slower to index by the column name first.
```py
>>> import time
>>> start_time = time.time()
>>> text = dataset[0]["text"]
>>> end_time = time.time()
>>> print(f"Elapsed time: {end_time - start_time:.4f} seconds")
Elapsed time: 0.0031 seconds
>>> start_time = time.time()
>>> text = dataset["text"][0]
>>> end_time = time.time()
>>> print(f"Elapsed time: {end_time - start_time:.4f} seconds")
Elapsed time: 0.0094 seconds
```
### Slicing
Slicing returns a slice - or subset - of the dataset, which is useful for viewing several rows at once. To slice a dataset, use the `:` operator to specify a range of positions.
```py
# Get the first three rows
>>> dataset[:3]
{'label': [1, 1, 1],
'text': ['the rock is destined to be the 21st century\'s new " conan " and that he\'s going to make a splash even greater than arnold schwarzenegger , jean-claud van damme or steven segal .',
'the gorgeously elaborate continuation of " the lord of the rings " trilogy is so huge that a column of words cannot adequately describe co-writer/director peter jackson\'s expanded vision of j . r . r . tolkien\'s middle-earth .',
'effective but too-tepid biopic']}
# Get rows between three and six
>>> dataset[3:6]
{'label': [1, 1, 1],
'text': ['if you sometimes like to go to the movies to have fun , wasabi is a good place to start .',
"emerges as something rare , an issue movie that's so honest and keenly observed that it doesn't feel like one .",
'the film provides some great insight into the neurotic mindset of all comics -- even those who have reached the absolute top of the game .']}
```
## IterableDataset
An [`IterableDataset`] is loaded when you set the `streaming` parameter to `True` in [`~datasets.load_dataset`]:
```py
>>> from datasets import load_dataset
>>> iterable_dataset = load_dataset("food101", split="train", streaming=True)
>>> for example in iterable_dataset:
... print(example)
... break
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=384x512 at 0x7F0681F5C520>, 'label': 6}
```
You can also create an [`IterableDataset`] from an *existing* [`Dataset`], but it is faster than streaming mode because the dataset is streamed from local files:
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("rotten_tomatoes", split="train")
>>> iterable_dataset = dataset.to_iterable_dataset()
```
An [`IterableDataset`] progressively iterates over a dataset one example at a time, so you don't have to wait for the whole dataset to download before you can use it. As you can imagine, this is quite useful for large datasets you want to use immediately!
However, this means an [`IterableDataset`]'s behavior is different from a regular [`Dataset`]. You don't get random access to examples in an [`IterableDataset`]. Instead, you should iterate over its elements, for example, by calling `next(iter())` or with a `for` loop to return the next item from the [`IterableDataset`]:
```py
>>> next(iter(iterable_dataset))
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=384x512 at 0x7F0681F59B50>,
'label': 6}
>>> for example in iterable_dataset:
... print(example)
... break
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=384x512 at 0x7F7479DE82B0>, 'label': 6}
```
You can return a subset of the dataset with a specific number of examples in it with [`IterableDataset.take`]:
```py
# Get first three examples
>>> list(iterable_dataset.take(3))
[{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=384x512 at 0x7F7479DEE9D0>,
'label': 6},
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=512x512 at 0x7F7479DE8190>,
'label': 6},
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=512x383 at 0x7F7479DE8310>,
'label': 6}]
```
But unlike [slicing](access/#slicing), [`IterableDataset.take`] creates a new [`IterableDataset`].

# Process image data
This guide shows specific methods for processing image datasets. Learn how to:
- Use [`~Dataset.map`] with image dataset.
- Apply data augmentations to a dataset with [`~Dataset.set_transform`].
For a guide on how to process any type of dataset, take a look at the <a class="underline decoration-sky-400 decoration-2 font-semibold" href="./process">general process guide</a>.
## Map
The [`~Dataset.map`] function can apply transforms over an entire dataset.
For example, create a basic [`Resize`](https://pytorch.org/vision/stable/generated/torchvision.transforms.Resize.html) function:
```py
>>> def transforms(examples):
... examples["pixel_values"] = [image.convert("RGB").resize((100,100)) for image in examples["image"]]
... return examples
```
Now use the [`~Dataset.map`] function to resize the entire dataset, and set `batched=True` to speed up the process by accepting batches of examples. The transform returns `pixel_values` as a cacheable `PIL.Image` object:
```py
>>> dataset = dataset.map(transforms, remove_columns=["image"], batched=True)
>>> dataset[0]
{'label': 6,
'pixel_values': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=100x100 at 0x7F058237BB10>}
```
The cache file saves time because you don't have to execute the same transform twice. The [`~Dataset.map`] function is best for operations you only run once per training - like resizing an image - instead of using it for operations executed for each epoch, like data augmentations.
[`~Dataset.map`] takes up some memory, but you can reduce its memory requirements with the following parameters:
- [`batch_size`](./package_reference/main_classes#datasets.DatasetDict.map.batch_size) determines the number of examples that are processed in one call to the transform function.
- [`writer_batch_size`](./package_reference/main_classes#datasets.DatasetDict.map.writer_batch_size) determines the number of processed examples that are kept in memory before they are stored away.
Both parameter values default to 1000, which can be expensive if you are storing images. Lower these values to use less memory when you use [`~Dataset.map`].
## Apply transforms
๐ค Datasets applies data augmentations from any library or package to your dataset. Transforms can be applied on-the-fly on batches of data with [`~Dataset.set_transform`], which consumes less disk space.
<Tip>
The following example uses [torchvision](https://pytorch.org/vision/stable/index.html), but feel free to use other data augmentation libraries like [Albumentations](https://albumentations.ai/docs/), [Kornia](https://kornia.readthedocs.io/en/latest/), and [imgaug](https://imgaug.readthedocs.io/en/latest/).
</Tip>
For example, if you'd like to change the color properties of an image randomly:
```py
>>> from torchvision.transforms import Compose, ColorJitter, ToTensor
>>> jitter = Compose(
... [
... ColorJitter(brightness=0.25, contrast=0.25, saturation=0.25, hue=0.7),
... ToTensor(),
... ]
... )
```
Create a function to apply the `ColorJitter` transform:
```py
>>> def transforms(examples):
... examples["pixel_values"] = [jitter(image.convert("RGB")) for image in examples["image"]]
... return examples
```
Apply the transform with the [`~Dataset.set_transform`] function:
```py
>>> dataset.set_transform(transforms)
```

# Quickstart
[[open-in-colab]]
This quickstart is intended for developers who are ready to dive into the code and see an example of how to integrate ๐ค Datasets into their model training workflow. If you're a beginner, we recommend starting with our [tutorials](./tutorial), where you'll get a more thorough introduction.
Each dataset is unique, and depending on the task, some datasets may require additional steps to prepare it for training. But you can always use ๐ค Datasets tools to load and process a dataset. The fastest and easiest way to get started is by loading an existing dataset from the [Hugging Face Hub](https://huggingface.co/datasets). There are thousands of datasets to choose from, spanning many tasks. Choose the type of dataset you want to work with, and let's get started!

<Tip>
Check out [Chapter 5](https://huggingface.co/course/chapter5/1?fw=pt) of the Hugging Face course to learn more about other important topics such as loading remote or local datasets, tools for cleaning up a dataset, and creating your own dataset.
</Tip>
Start by installing ๐ค Datasets:
```bash
pip install datasets
```
๐ค Datasets also support audio and image data formats:
* To work with audio datasets, install the [`Audio`] feature:
```bash
pip install datasets[audio]
```
* To work with image datasets, install the [`Image`] feature:
```bash
pip install datasets[vision]
```
Besides ๐ค Datasets, make sure your preferred machine learning framework is installed:
<frameworkcontent>
<pt>
```bash
pip install torch
```
</pt>
<tf>
```bash
pip install tensorflow
```
</tf>
</frameworkcontent>
## Audio
Audio datasets are loaded just like text datasets. However, an audio dataset is preprocessed a bit differently. Instead of a tokenizer, you'll need a [feature extractor](https://huggingface.co/docs/transformers/main_classes/feature_extractor#feature-extractor). An audio input may also require resampling its sampling rate to match the sampling rate of the pretrained model you're using. In this quickstart, you'll prepare the [MInDS-14](https://huggingface.co/datasets/PolyAI/minds14) dataset for a model train on and classify the banking issue a customer is having.
**1**. Load the MInDS-14 dataset by providing the [`load_dataset`] function with the dataset name, dataset configuration (not all datasets will have a configuration), and a dataset split:
```py
>>> from datasets import load_dataset, Audio
>>> dataset = load_dataset("PolyAI/minds14", "en-US", split="train")
```
**2**. Next, load a pretrained [Wav2Vec2](https://huggingface.co/facebook/wav2vec2-base) model and its corresponding feature extractor from the [๐ค Transformers](https://huggingface.co/transformers/) library. It is totally normal to see a warning after you load the model about some weights not being initialized. This is expected because you are loading this model checkpoint for training with another task.
```py
>>> from transformers import AutoModelForAudioClassification, AutoFeatureExtractor
>>> model = AutoModelForAudioClassification.from_pretrained("facebook/wav2vec2-base")
>>> feature_extractor = AutoFeatureExtractor.from_pretrained("facebook/wav2vec2-base")
```
**3**. The [MInDS-14](https://huggingface.co/datasets/PolyAI/minds14) dataset card indicates the sampling rate is 8kHz, but the Wav2Vec2 model was pretrained on a sampling rate of 16kHZ. You'll need to upsample the `audio` column with the [`~Dataset.cast_column`] function and [`Audio`] feature to match the model's sampling rate.
```py
>>> dataset = dataset.cast_column("audio", Audio(sampling_rate=16000))
>>> dataset[0]["audio"]
{'array': array([ 2.3443763e-05, 2.1729663e-04, 2.2145823e-04, ...,
3.8356509e-05, -7.3497440e-06, -2.1754686e-05], dtype=float32),
'path': '/root/.cache/huggingface/datasets/downloads/extracted/f14948e0e84be638dd7943ac36518a4cf3324e8b7aa331c5ab11541518e9368c/en-US~JOINT_ACCOUNT/602ba55abb1e6d0fbce92065.wav',
'sampling_rate': 16000}
```
**4**. Create a function to preprocess the audio `array` with the feature extractor, and truncate and pad the sequences into tidy rectangular tensors. The most important thing to remember is to call the audio `array` in the feature extractor since the `array` - the actual speech signal - is the model input.
Once you have a preprocessing function, use the [`~Dataset.map`] function to speed up processing by applying the function to batches of examples in the dataset.
```py
>>> def preprocess_function(examples):
... audio_arrays = [x["array"] for x in examples["audio"]]
... inputs = feature_extractor(
... audio_arrays,
... sampling_rate=16000,
... padding=True,
... max_length=100000,
... truncation=True,
... )
... return inputs
>>> dataset = dataset.map(preprocess_function, batched=True)
```
**5**. Use the [`~Dataset.rename_column`] function to rename the `intent_class` column to `labels`, which is the expected input name in [Wav2Vec2ForSequenceClassification](https://huggingface.co/docs/transformers/main/en/model_doc/wav2vec2#transformers.Wav2Vec2ForSequenceClassification):
```py
>>> dataset = dataset.rename_column("intent_class", "labels")
```
**6**. Set the dataset format according to the machine learning framework you're using.
<frameworkcontent>
<pt>
Use the [`~Dataset.set_format`] function to set the dataset format to `torch` and specify the columns you want to format. This function applies formatting on-the-fly. After converting to PyTorch tensors, wrap the dataset in [`torch.utils.data.DataLoader`](https://alband.github.io/doc_view/data.html?highlight=torch%20utils%20data%20dataloader#torch.utils.data.DataLoader):
```py
>>> from torch.utils.data import DataLoader
>>> dataset.set_format(type="torch", columns=["input_values", "labels"])
>>> dataloader = DataLoader(dataset, batch_size=4)
```
</pt>
<tf>
Use the [`~transformers.TFPreTrainedModel.prepare_tf_dataset`] method from ๐ค Transformers to prepare the dataset to be compatible with
TensorFlow, and ready to train/fine-tune a model, as it wraps a HuggingFace [`~datasets.Dataset`] as a `tf.data.Dataset`
with collation and batching, so one can pass it directly to Keras methods like `fit()` without further modification.
```py
>>> import tensorflow as tf
>>> tf_dataset = model.prepare_tf_dataset(
... dataset,
... batch_size=4,
... shuffle=True,
... )
```
</tf>
</frameworkcontent>
**7**. Start training with your machine learning framework! Check out the ๐ค Transformers [audio classification guide](https://huggingface.co/docs/transformers/tasks/audio_classification) for an end-to-end example of how to train a model on an audio dataset.
## Vision
Image datasets are loaded just like text datasets. However, instead of a tokenizer, you'll need a [feature extractor](https://huggingface.co/docs/transformers/main_classes/feature_extractor#feature-extractor) to preprocess the dataset. Applying data augmentation to an image is common in computer vision to make the model more robust against overfitting. You're free to use any data augmentation library you want, and then you can apply the augmentations with ๐ค Datasets. In this quickstart, you'll load the [Beans](https://huggingface.co/datasets/beans) dataset and get it ready for the model to train on and identify disease from the leaf images.
**1**. Load the Beans dataset by providing the [`load_dataset`] function with the dataset name and a dataset split:
```py
>>> from datasets import load_dataset, Image
>>> dataset = load_dataset("beans", split="train")
```
Most image models work with RBG images. If your dataset contains images in a different mode, you can use the [`~Dataset.cast_column`] function to set the mode to RGB:
```py
>>> dataset = dataset.cast_column("image", Image(mode="RGB"))
```
The Beans dataset contains only RGB images, so this step is unnecessary here.
**2**. Now you can add some data augmentations with any library ([Albumentations](https://albumentations.ai/), [imgaug](https://imgaug.readthedocs.io/en/latest/), [Kornia](https://kornia.readthedocs.io/en/latest/)) you like. Here, you'll use [torchvision](https://pytorch.org/vision/stable/transforms.html) to randomly change the color properties of an image:
```py
>>> from torchvision.transforms import Compose, ColorJitter, ToTensor
>>> jitter = Compose(
... [ColorJitter(brightness=0.5, hue=0.5), ToTensor()]
... )
```
**3**. Create a function to apply your transform to the dataset and generate the model input: `pixel_values`.
```python
>>> def transforms(examples):
... examples["pixel_values"] = [jitter(image.convert("RGB")) for image in examples["image"]]
... return examples
```
**4**. Use the [`~Dataset.with_transform`] function to apply the data augmentations on-the-fly:
```py
>>> dataset = dataset.with_transform(transforms)
```
**5**. Set the dataset format according to the machine learning framework you're using.
<frameworkcontent>
<pt>
Wrap the dataset in [`torch.utils.data.DataLoader`](https://alband.github.io/doc_view/data.html?highlight=torch%20utils%20data%20dataloader#torch.utils.data.DataLoader). You'll also need to create a collate function to collate the samples into batches:
```py
>>> from torch.utils.data import DataLoader
>>> def collate_fn(examples):
... images = []
... labels = []
... for example in examples:
... images.append((example["pixel_values"]))
... labels.append(example["labels"])
...
... pixel_values = torch.stack(images)
... labels = torch.tensor(labels)
... return {"pixel_values": pixel_values, "labels": labels}
>>> dataloader = DataLoader(dataset, collate_fn=collate_fn, batch_size=4)
```
</pt>
<tf>
Use the [`~transformers.TFPreTrainedModel.prepare_tf_dataset`] method from ๐ค Transformers to prepare the dataset to be compatible with
TensorFlow, and ready to train/fine-tune a model, as it wraps a HuggingFace [`~datasets.Dataset`] as a `tf.data.Dataset`
with collation and batching, so one can pass it directly to Keras methods like `fit()` without further modification.
Before you start, make sure you have up-to-date versions of `albumentations` and `cv2` installed:
```bash
pip install -U albumentations opencv-python
```
```py
>>> import albumentations
>>> import numpy as np
>>> transform = albumentations.Compose([
... albumentations.RandomCrop(width=256, height=256),
... albumentations.HorizontalFlip(p=0.5),
... albumentations.RandomBrightnessContrast(p=0.2),
... ])
>>> def transforms(examples):
... examples["pixel_values"] = [
... transform(image=np.array(image))["image"] for image in examples["image"]
... ]
... return examples
>>> dataset.set_transform(transforms)
>>> tf_dataset = model.prepare_tf_dataset(
... dataset,
... batch_size=4,
... shuffle=True,
... )
```
</tf>
</frameworkcontent>
**6**. Start training with your machine learning framework! Check out the ๐ค Transformers [image classification guide](https://huggingface.co/docs/transformers/tasks/image_classification) for an end-to-end example of how to train a model on an image dataset.
## NLP
Text needs to be tokenized into individual tokens by a [tokenizer](https://huggingface.co/docs/transformers/main_classes/tokenizer). For the quickstart, you'll load the [Microsoft Research Paraphrase Corpus (MRPC)](https://huggingface.co/datasets/glue/viewer/mrpc) training dataset to train a model to determine whether a pair of sentences mean the same thing.
**1**. Load the MRPC dataset by providing the [`load_dataset`] function with the dataset name, dataset configuration (not all datasets will have a configuration), and dataset split:
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("glue", "mrpc", split="train")
```
**2**. Next, load a pretrained [BERT](https://huggingface.co/bert-base-uncased) model and its corresponding tokenizer from the [๐ค Transformers](https://huggingface.co/transformers/) library. It is totally normal to see a warning after you load the model about some weights not being initialized. This is expected because you are loading this model checkpoint for training with another task.
```py
>>> from transformers import AutoModelForSequenceClassification, AutoTokenizer
>>> model = AutoModelForSequenceClassification.from_pretrained("bert-base-uncased")
>>> tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
===PT-TF-SPLIT===
>>> from transformers import TFAutoModelForSequenceClassification, AutoTokenizer
>>> model = TFAutoModelForSequenceClassification.from_pretrained("bert-base-uncased")
>>> tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
```
**3**. Create a function to tokenize the dataset, and you should also truncate and pad the text into tidy rectangular tensors. The tokenizer generates three new columns in the dataset: `input_ids`, `token_type_ids`, and an `attention_mask`. These are the model inputs.
Use the [`~Dataset.map`] function to speed up processing by applying your tokenization function to batches of examples in the dataset:
```py
>>> def encode(examples):
... return tokenizer(examples["sentence1"], examples["sentence2"], truncation=True, padding="max_length")
>>> dataset = dataset.map(encode, batched=True)
>>> dataset[0]
{'sentence1': 'Amrozi accused his brother , whom he called " the witness " , of deliberately distorting his evidence .',
'sentence2': 'Referring to him as only " the witness " , Amrozi accused his brother of deliberately distorting his evidence .',
'label': 1,
'idx': 0,
'input_ids': array([ 101, 7277, 2180, 5303, 4806, 1117, 1711, 117, 2292, 1119, 1270, 107, 1103, 7737, 107, 117, 1104, 9938, 4267, 12223, 21811, 1117, 2554, 119, 102, 11336, 6732, 3384, 1106, 1140, 1112, 1178, 107, 1103, 7737, 107, 117, 7277, 2180, 5303, 4806, 1117, 1711, 1104, 9938, 4267, 12223, 21811, 1117, 2554, 119, 102]),
'token_type_ids': array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]),
'attention_mask': array([1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1])}
```
**4**. Rename the `label` column to `labels`, which is the expected input name in [BertForSequenceClassification](https://huggingface.co/docs/transformers/main/en/model_doc/bert#transformers.BertForSequenceClassification):
```py
>>> dataset = dataset.map(lambda examples: {"labels": examples["label"]}, batched=True)
```
**5**. Set the dataset format according to the machine learning framework you're using.
<frameworkcontent>
<pt>
Use the [`~Dataset.set_format`] function to set the dataset format to `torch` and specify the columns you want to format. This function applies formatting on-the-fly. After converting to PyTorch tensors, wrap the dataset in [`torch.utils.data.DataLoader`](https://alband.github.io/doc_view/data.html?highlight=torch%20utils%20data%20dataloader#torch.utils.data.DataLoader):
```py
>>> import torch
>>> dataset.set_format(type="torch", columns=["input_ids", "token_type_ids", "attention_mask", "labels"])
>>> dataloader = torch.utils.data.DataLoader(dataset, batch_size=32)
```
</pt>
<tf>
Use the [`~transformers.TFPreTrainedModel.prepare_tf_dataset`] method from ๐ค Transformers to prepare the dataset to be compatible with
TensorFlow, and ready to train/fine-tune a model, as it wraps a HuggingFace [`~datasets.Dataset`] as a `tf.data.Dataset`
with collation and batching, so one can pass it directly to Keras methods like `fit()` without further modification.
```py
>>> import tensorflow as tf
>>> tf_dataset = model.prepare_tf_dataset(
... dataset,
... batch_size=4,
... shuffle=True,
... )
```
</tf>
</frameworkcontent>
**6**. Start training with your machine learning framework! Check out the ๐ค Transformers [text classification guide](https://huggingface.co/docs/transformers/tasks/sequence_classification) for an end-to-end example of how to train a model on a text dataset.
## What's next?
This completes the ๐ค Datasets quickstart! You can load any text, audio, or image dataset with a single function and get it ready for your model to train on.
For your next steps, take a look at our [How-to guides](./how_to) and learn how to do more specific things like loading different dataset formats, aligning labels, and streaming large datasets. If you're interested in learning more about ๐ค Datasets core concepts, grab a cup of coffee and read our [Conceptual Guides](./about_arrow)!

Resolve the paths and URLs of the data files from the pattern passed by the user.
You can use patterns to resolve multiple local files. Here are a few examples:
- *.csv to match all the CSV files at the first level
- **.csv to match all the CSV files at any level
- data/* to match all the files inside "data"
- data/** to match all the files inside "data" and its subdirectories
The patterns are resolved using the fsspec glob. In fsspec>=2023.12.0 this is equivalent to
Python's glob.glob, Path.glob, Path.match and fnmatch where ** is unsupported with a prefix/suffix
other than a forward slash /.
More generally:
- '*' matches any character except a forward-slash (to match just the file or directory name)
- '**' matches any character including a forward-slash /
Hidden files and directories (i.e. whose names start with a dot) are ignored, unless they are explicitly requested.
The same applies to special directories that start with a double underscore like "__pycache__".
You can still include one if the pattern explicilty mentions it:
- to include a hidden file: "*/.hidden.txt" or "*/.*"
- to include a hidden directory: ".hidden/*" or ".*/*"
- to include a special directory: "__special__/*" or "__*/*"

>>> resolve_pattern("docs/**/*.py", base_path)
[/Users/mariosasko/Desktop/projects/datasets/docs/source/_config.py']

# Summary [[summary]]
That was a lot of information! Let's summarize:
- Reinforcement Learning is a computational approach of learning from actions. We build an agent that learns from the environment **by interacting with it through trial and error** and receiving rewards (negative or positive) as feedback.
- The goal of any RL agent is to maximize its expected cumulative reward (also called expected return) because RL is based on the **reward hypothesis**, which is that **all goals can be described as the maximization of the expected cumulative reward.**
- The RL process is a loop that outputs a sequence of **state, action, reward and next state.**
- To calculate the expected cumulative reward (expected return), we discount the rewards: the rewards that come sooner (at the beginning of the game) **are more probable to happen since they are more predictable than the long term future reward.**
- To solve an RL problem, you want to **find an optimal policy**. The policy is the โbrainโ of your agent, which will tell us **what action to take given a state.** The optimal policy is the one which **gives you the actions that maximize the expected return.**
- There are two ways to find your optimal policy:
1. By training your policy directly: **policy-based methods.**
2. By training a value function that tells us the expected return the agent will get at each state and use this function to define our policy: **value-based methods.**
- Finally, we speak about Deep RL because we introduce **deep neural networks to estimate the action to take (policy-based) or to estimate the value of a state (value-based)** hence the name โdeepโ.

# Second Quiz [[quiz2]]
The best way to learn and [to avoid the illusion of competence](https://www.coursera.org/lecture/learning-how-to-learn/illusions-of-competence-BuFzf) **is to test yourself.** This will help you to find **where you need to reinforce your knowledge**.
### Q1: What is Q-Learning?
<Question
choices={[
{
text: "The algorithm we use to train our Q-function",
explain: "",
correct: true
},
{
text: "A value function",
explain: "It's an action-value function since it determines the value of being at a particular state and taking a specific action at that state",
},
{
text: "An algorithm that determines the value of being at a particular state and taking a specific action at that state",
explain: "Q-function is the function that determines the value of being at a particular state and taking a specific action at that state.",
},
{
text: "A table",
explain: "Q-learning is not a Q-table. The Q-function is the algorithm that will feed the Q-table."
}
]}
/>
### Q2: What is a Q-table?
<Question
choices={[
{
text: "An algorithm we use in Q-Learning",
explain: "",
},
{
text: "Q-table is the internal memory of our agent",
explain: "",
correct: true
},
{
text: "In Q-table each cell corresponds a state value",
explain: "Each cell corresponds to a state-action value pair value. Not a state value.",
}
]}
/>
### Q3: Why if we have an optimal Q-function Q* we have an optimal policy?
<details>
<summary>Solution</summary>
Because if we have an optimal Q-function, we have an optimal policy since we know for each state what is the best action to take.
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit3/link-value-policy.jpg" alt="link value policy"/>
</details>
### Q4: Can you explain what is Epsilon-Greedy Strategy?
<details>
<summary>Solution</summary>
Epsilon Greedy Strategy is a policy that handles the exploration/exploitation trade-off.
The idea is that we define epsilon ษ = 1.0:
- With *probability 1 โ ษ* : we do exploitation (aka our agent selects the action with the highest state-action pair value).
- With *probability ษ* : we do exploration (trying random action).

Now that we've studied the theory behind Reinforce, **youโre ready to code your Reinforce agent with PyTorch**. And you'll test its robustness using CartPole-v1 and PixelCopter,.
You'll then be able to iterate and improve this implementation for more advanced environments.
<figure class="image table text-center m-0 w-full">
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit6/envs.gif" alt="Environments"/>
</figure>
To validate this hands-on for the certification process, you need to push your trained models to the Hub and:
- Get a result of >= 350 for `Cartpole-v1`
- Get a result of >= 5 for `PixelCopter`.
To find your result, go to the leaderboard and find your model, **the result = mean_reward - std of reward**. **If you don't see your model on the leaderboard, go at the bottom of the leaderboard page and click on the refresh button**.
**If you don't find your model, go to the bottom of the page and click on the refresh button.**
For more information about the certification process, check this section ๐ https://huggingface.co/deep-rl-course/en/unit0/introduction#certification-process
And you can check your progress here ๐ https://huggingface.co/spaces/ThomasSimonini/Check-my-progress-Deep-RL-Course
**To start the hands-on click on Open In Colab button** ๐ :
[](https://colab.research.google.com/github/huggingface/deep-rl-class/blob/master/notebooks/unit4/unit4.ipynb)
We strongly **recommend students use Google Colab for the hands-on exercises** instead of running them on their personal computers.
By using Google Colab, **you can focus on learning and experimenting without worrying about the technical aspects** of setting up your environments.
# Unit 4: Code your first Deep Reinforcement Learning Algorithm with PyTorch: Reinforce. And test its robustness ๐ช
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit6/thumbnail.png" alt="thumbnail"/>
In this notebook, you'll code your first Deep Reinforcement Learning algorithm from scratch: Reinforce (also called Monte Carlo Policy Gradient).
Reinforce is a *Policy-based method*: a Deep Reinforcement Learning algorithm that tries **to optimize the policy directly without using an action-value function**.
More precisely, Reinforce is a *Policy-gradient method*, a subclass of *Policy-based methods* that aims **to optimize the policy directly by estimating the weights of the optimal policy using gradient ascent**.
To test its robustness, we're going to train it in 2 different simple environments:
- Cartpole-v1
- PixelcopterEnv
โฌ๏ธ Here is an example of what **you will achieve at the end of this notebook.** โฌ๏ธ
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit6/envs.gif" alt="Environments"/>
### ๐ฎ Environments:
- [CartPole-v1](https://www.gymlibrary.dev/environments/classic_control/cart_pole/)
- [PixelCopter](https://pygame-learning-environment.readthedocs.io/en/latest/user/games/pixelcopter.html)
### ๐ RL-Library:
- Python
- PyTorch
We're constantly trying to improve our tutorials, so **if you find some issues in this notebook**, please [open an issue on the GitHub Repo](https://github.com/huggingface/deep-rl-class/issues).
## Objectives of this notebook ๐
At the end of the notebook, you will:
- Be able to **code a Reinforce algorithm from scratch using PyTorch.**
- Be able to **test the robustness of your agent using simple environments.**
- Be able to **push your trained agent to the Hub** with a nice video replay and an evaluation score ๐ฅ.
## Prerequisites ๐๏ธ
Before diving into the notebook, you need to:
๐ฒ ๐ [Study Policy Gradients by reading Unit 4](https://huggingface.co/deep-rl-course/unit4/introduction)
# Let's code Reinforce algorithm from scratch ๐ฅ
## Some advice ๐ก
It's better to run this colab in a copy on your Google Drive, so that **if it times out** you still have the saved notebook on your Google Drive and do not need to fill everything in from scratch.
To do that you can either do `Ctrl + S` or `File > Save a copy in Google Drive.`
## Set the GPU ๐ช
- To **accelerate the agent's training, we'll use a GPU**. To do that, go to `Runtime > Change Runtime type`
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/notebooks/gpu-step1.jpg" alt="GPU Step 1">
- `Hardware Accelerator > GPU`
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/notebooks/gpu-step2.jpg" alt="GPU Step 2">
## Create a virtual display ๐ฅ
During the notebook, we'll need to generate a replay video. To do so, with colab, **we need to have a virtual screen to be able to render the environment** (and thus record the frames).
The following cell will install the librairies and create and run a virtual screen ๐ฅ
```python
%%capture
!apt install python-opengl
!apt install ffmpeg
!apt install xvfb
!pip install pyvirtualdisplay
!pip install pyglet==1.5.1
```
```python
# Virtual display
from pyvirtualdisplay import Display
virtual_display = Display(visible=0, size=(1400, 900))
virtual_display.start()
```
## Install the dependencies ๐ฝ
The first step is to install the dependencies. Weโll install multiple ones:
- `gym`
- `gym-games`: Extra gym environments made with PyGame.
- `huggingface_hub`: The Hub works as a central place where anyone can share and explore models and datasets. It has versioning, metrics, visualizations, and other features that will allow you to easily collaborate with others.
You may be wondering why we install gym and not gymnasium, a more recent version of gym? **Because the gym-games we are using are not updated yet with gymnasium**.
The differences you'll encounter here:
- In `gym` we don't have `terminated` and `truncated` but only `done`.
- In `gym` using `env.step()` returns `state, reward, done, info`
You can learn more about the differences between Gym and Gymnasium here ๐ https://gymnasium.farama.org/content/migration-guide/
You can see here all the Reinforce models available ๐ https://huggingface.co/models?other=reinforce
And you can find all the Deep Reinforcement Learning models here ๐ https://huggingface.co/models?pipeline_tag=reinforcement-learning
```bash
!pip install -r https://raw.githubusercontent.com/huggingface/deep-rl-class/main/notebooks/unit4/requirements-unit4.txt
```
## Import the packages ๐ฆ
In addition to importing the installed libraries, we also import:
- `imageio`: A library that will help us to generate a replay video
```python
import numpy as np
from collections import deque
import matplotlib.pyplot as plt
%matplotlib inline
# PyTorch
import torch
import torch.nn as nn
import torch.nn.functional as F
import torch.optim as optim
from torch.distributions import Categorical
# Gym
import gym
import gym_pygame
# Hugging Face Hub
from huggingface_hub import notebook_login # To log to our Hugging Face account to be able to upload models to the Hub.
import imageio
```
## Check if we have a GPU
- Let's check if we have a GPU
- If it's the case you should see `device:cuda0`
```python
device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")
```
```python
print(device)
```
We're now ready to implement our Reinforce algorithm ๐ฅ
# First agent: Playing CartPole-v1 ๐ค
## Create the CartPole environment and understand how it works
### [The environment ๐ฎ](https://www.gymlibrary.dev/environments/classic_control/cart_pole/)
### Why do we use a simple environment like CartPole-v1?
As explained in [Reinforcement Learning Tips and Tricks](https://stable-baselines3.readthedocs.io/en/master/guide/rl_tips.html), when you implement your agent from scratch, you need **to be sure that it works correctly and find bugs with easy environments before going deeper** as finding bugs will be much easier in simple environments.
> Try to have some โsign of lifeโ on toy problems
> Validate the implementation by making it run on harder and harder envs (you can compare results against the RL zoo). You usually need to run hyperparameter optimization for that step.
### The CartPole-v1 environment
> A pole is attached by an un-actuated joint to a cart, which moves along a frictionless track. The pendulum is placed upright on the cart and the goal is to balance the pole by applying forces in the left and right direction on the cart.
So, we start with CartPole-v1. The goal is to push the cart left or right **so that the pole stays in the equilibrium.**
The episode ends if:
- The pole Angle is greater than ยฑ12ยฐ
- The Cart Position is greater than ยฑ2.4
- The episode length is greater than 500
We get a reward ๐ฐ of +1 every timestep that the Pole stays in the equilibrium.
```python
env_id = "CartPole-v1"
# Create the env
env = gym.make(env_id)
# Create the evaluation env
eval_env = gym.make(env_id)
# Get the state space and action space
s_size = env.observation_space.shape[0]
a_size = env.action_space.n
```
```python
print("_____OBSERVATION SPACE_____ \n")
print("The State Space is: ", s_size)
print("Sample observation", env.observation_space.sample()) # Get a random observation
```
```python
print("\n _____ACTION SPACE_____ \n")
print("The Action Space is: ", a_size)
print("Action Space Sample", env.action_space.sample()) # Take a random action
```
## Let's build the Reinforce Architecture
This implementation is based on three implementations:
- [PyTorch official Reinforcement Learning example](https://github.com/pytorch/examples/blob/main/reinforcement_learning/reinforce.py)
- [Udacity Reinforce](https://github.com/udacity/deep-reinforcement-learning/blob/master/reinforce/REINFORCE.ipynb)
- [Improvement of the integration by Chris1nexus](https://github.com/huggingface/deep-rl-class/pull/95)
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit6/reinforce.png" alt="Reinforce"/>
So we want:
- Two fully connected layers (fc1 and fc2).
- To use ReLU as activation function of fc1
- To use Softmax to output a probability distribution over actions
```python
class Policy(nn.Module):
def __init__(self, s_size, a_size, h_size):
super(Policy, self).__init__()
# Create two fully connected layers
def forward(self, x):
# Define the forward pass
# state goes to fc1 then we apply ReLU activation function
# fc1 outputs goes to fc2
# We output the softmax
def act(self, state):
"""
Given a state, take action
"""
state = torch.from_numpy(state).float().unsqueeze(0).to(device)
probs = self.forward(state).cpu()
m = Categorical(probs)
action = np.argmax(m)
return action.item(), m.log_prob(action)
```
### Solution
```python
class Policy(nn.Module):
def __init__(self, s_size, a_size, h_size):
super(Policy, self).__init__()
self.fc1 = nn.Linear(s_size, h_size)
self.fc2 = nn.Linear(h_size, a_size)
def forward(self, x):
x = F.relu(self.fc1(x))
x = self.fc2(x)
return F.softmax(x, dim=1)
def act(self, state):
state = torch.from_numpy(state).float().unsqueeze(0).to(device)
probs = self.forward(state).cpu()
m = Categorical(probs)
action = np.argmax(m)
return action.item(), m.log_prob(action)
```
I made a mistake, can you guess where?
- To find out let's make a forward pass:
```python
debug_policy = Policy(s_size, a_size, 64).to(device)
debug_policy.act(env.reset())
```
- Here we see that the error says `ValueError: The value argument to log_prob must be a Tensor`
- It means that `action` in `m.log_prob(action)` must be a Tensor **but it's not.**
- Do you know why? Check the act function and try to see why it does not work.
Advice ๐ก: Something is wrong in this implementation. Remember that for the act function **we want to sample an action from the probability distribution over actions**.
### (Real) Solution
```python
class Policy(nn.Module):
def __init__(self, s_size, a_size, h_size):
super(Policy, self).__init__()
self.fc1 = nn.Linear(s_size, h_size)
self.fc2 = nn.Linear(h_size, a_size)
def forward(self, x):
x = F.relu(self.fc1(x))
x = self.fc2(x)
return F.softmax(x, dim=1)
def act(self, state):
state = torch.from_numpy(state).float().unsqueeze(0).to(device)
probs = self.forward(state).cpu()
m = Categorical(probs)
action = m.sample()
return action.item(), m.log_prob(action)
```
By using CartPole, it was easier to debug since **we know that the bug comes from our integration and not from our simple environment**.
- Since **we want to sample an action from the probability distribution over actions**, we can't use `action = np.argmax(m)` since it will always output the action that has the highest probability.
- We need to replace this with `action = m.sample()` which will sample an action from the probability distribution P(.|s)
### Let's build the Reinforce Training Algorithm
This is the Reinforce algorithm pseudocode:
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit6/pg_pseudocode.png" alt="Policy gradient pseudocode"/>
- When we calculate the return Gt (line 6), we see that we calculate the sum of discounted rewards **starting at timestep t**.
- Why? Because our policy should only **reinforce actions on the basis of the consequences**: so rewards obtained before taking an action are useless (since they were not because of the action), **only the ones that come after the action matters**.
- Before coding this you should read this section [don't let the past distract you](https://spinningup.openai.com/en/latest/spinningup/rl_intro3.html#don-t-let-the-past-distract-you) that explains why we use reward-to-go policy gradient.
We use an interesting technique coded by [Chris1nexus](https://github.com/Chris1nexus) to **compute the return at each timestep efficiently**. The comments explained the procedure. Don't hesitate also [to check the PR explanation](https://github.com/huggingface/deep-rl-class/pull/95)
But overall the idea is to **compute the return at each timestep efficiently**.
The second question you may ask is **why do we minimize the loss**? Didn't we talk about Gradient Ascent, not Gradient Descent earlier?
- We want to maximize our utility function $J(\theta)$, but in PyTorch and TensorFlow, it's better to **minimize an objective function.**
- So let's say we want to reinforce action 3 at a certain timestep. Before training this action P is 0.25.
- So we want to modify \\(theta \\) such that \\(\pi_\theta(a_3|s; \theta) > 0.25 \\)
- Because all P must sum to 1, max \\(pi_\theta(a_3|s; \theta)\\) will **minimize other action probability.**
- So we should tell PyTorch **to min \\(1 - \pi_\theta(a_3|s; \theta)\\).**
- This loss function approaches 0 as \\(\pi_\theta(a_3|s; \theta)\\) nears 1.
- So we are encouraging the gradient to max \\(\pi_\theta(a_3|s; \theta)\\)

## Train it
- We're now ready to train our agent.
- But first, we define a variable containing all the training hyperparameters.
- You can change the training parameters (and should ๐)
```python
cartpole_hyperparameters = {
"h_size": 16,
"n_training_episodes": 1000,
"n_evaluation_episodes": 10,
"max_t": 1000,
"gamma": 1.0,
"lr": 1e-2,
"env_id": env_id,
"state_space": s_size,
"action_space": a_size,
}
```
```python
# Create policy and place it to the device
cartpole_policy = Policy(
cartpole_hyperparameters["state_space"],
cartpole_hyperparameters["action_space"],
cartpole_hyperparameters["h_size"],
).to(device)
cartpole_optimizer = optim.Adam(cartpole_policy.parameters(), lr=cartpole_hyperparameters["lr"])
```
```python
scores = reinforce(
cartpole_policy,
cartpole_optimizer,
cartpole_hyperparameters["n_training_episodes"],
cartpole_hyperparameters["max_t"],
cartpole_hyperparameters["gamma"],
100,
)
```
## Define evaluation method ๐
- Here we define the evaluation method that we're going to use to test our Reinforce agent.
```python
def evaluate_agent(env, max_steps, n_eval_episodes, policy):
"""
Evaluate the agent for ``n_eval_episodes`` episodes and returns average reward and std of reward.
:param env: The evaluation environment
:param n_eval_episodes: Number of episode to evaluate the agent
:param policy: The Reinforce agent
"""
episode_rewards = []
for episode in range(n_eval_episodes):
state = env.reset()
step = 0
done = False
total_rewards_ep = 0
for step in range(max_steps):
action, _ = policy.act(state)
new_state, reward, done, info = env.step(action)
total_rewards_ep += reward
if done:
break
state = new_state
episode_rewards.append(total_rewards_ep)
mean_reward = np.mean(episode_rewards)
std_reward = np.std(episode_rewards)
return mean_reward, std_reward
```
## Evaluate our agent ๐
```python
evaluate_agent(
eval_env, cartpole_hyperparameters["max_t"], cartpole_hyperparameters["n_evaluation_episodes"], cartpole_policy
)
```
### Publish our trained model on the Hub ๐ฅ
Now that we saw we got good results after the training, we can publish our trained model on the hub ๐ค with one line of code.

By using `push_to_hub`, **you evaluate, record a replay, generate a model card of your agent, and push it to the Hub**.
This way:
- You can **showcase our work** ๐ฅ
- You can **visualize your agent playing** ๐
- You can **share an agent with the community that others can use** ๐พ
- You can **access a leaderboard ๐ to see how well your agent is performing compared to your classmates** ๐ https://huggingface.co/spaces/huggingface-projects/Deep-Reinforcement-Learning-Leaderboard
To be able to share your model with the community there are three more steps to follow:
1๏ธโฃ (If it's not already done) create an account to HF โก https://huggingface.co/join
2๏ธโฃ Sign in and then, you need to store your authentication token from the Hugging Face website.
- Create a new token (https://huggingface.co/settings/tokens) **with write role**
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/notebooks/create-token.jpg" alt="Create HF Token">
```python
notebook_login()
```
If you don't want to use Google Colab or a Jupyter Notebook, you need to use this command instead: `huggingface-cli login` (or `login`)
3๏ธโฃ We're now ready to push our trained agent to the ๐ค Hub ๐ฅ using `package_to_hub()` function
```python
repo_id = "" # TODO Define your repo id {username/Reinforce-{model-id}}
push_to_hub(
repo_id,
cartpole_policy, # The model we want to save
cartpole_hyperparameters, # Hyperparameters
eval_env, # Evaluation environment
video_fps=30
)
```
Now that we tested the robustness of our implementation, let's try a more complex environment: PixelCopter ๐
## Second agent: PixelCopter ๐
### Study the PixelCopter environment ๐
- [The Environment documentation](https://pygame-learning-environment.readthedocs.io/en/latest/user/games/pixelcopter.html)
```python
env_id = "Pixelcopter-PLE-v0"
env = gym.make(env_id)
eval_env = gym.make(env_id)
s_size = env.observation_space.shape[0]
a_size = env.action_space.n
```
```python
print("_____OBSERVATION SPACE_____ \n")
print("The State Space is: ", s_size)
print("Sample observation", env.observation_space.sample()) # Get a random observation
```
```python
print("\n _____ACTION SPACE_____ \n")
print("The Action Space is: ", a_size)
print("Action Space Sample", env.action_space.sample()) # Take a random action
```
The observation space (7) ๐:
- player y position
- player velocity
- player distance to floor
- player distance to ceiling
- next block x distance to player
- next blocks top y location
- next blocks bottom y location
The action space(2) ๐ฎ:
- Up (press accelerator)
- Do nothing (don't press accelerator)
The reward function ๐ฐ:
- For each vertical block it passes, it gains a positive reward of +1. Each time a terminal state is reached it receives a negative reward of -1.
### Define the new Policy ๐ง
- We need to have a deeper neural network since the environment is more complex
```python
class Policy(nn.Module):
def __init__(self, s_size, a_size, h_size):
super(Policy, self).__init__()
# Define the three layers here
def forward(self, x):
# Define the forward process here
return F.softmax(x, dim=1)
def act(self, state):
state = torch.from_numpy(state).float().unsqueeze(0).to(device)
probs = self.forward(state).cpu()
m = Categorical(probs)
action = m.sample()
return action.item(), m.log_prob(action)
```
#### Solution
```python
class Policy(nn.Module):
def __init__(self, s_size, a_size, h_size):
super(Policy, self).__init__()
self.fc1 = nn.Linear(s_size, h_size)
self.fc2 = nn.Linear(h_size, h_size * 2)
self.fc3 = nn.Linear(h_size * 2, a_size)
def forward(self, x):
x = F.relu(self.fc1(x))
x = F.relu(self.fc2(x))
x = self.fc3(x)
return F.softmax(x, dim=1)
def act(self, state):
state = torch.from_numpy(state).float().unsqueeze(0).to(device)
probs = self.forward(state).cpu()
m = Categorical(probs)
action = m.sample()
return action.item(), m.log_prob(action)
```
### Define the hyperparameters โ๏ธ
- Because this environment is more complex.
- Especially for the hidden size, we need more neurons.
```python
pixelcopter_hyperparameters = {
"h_size": 64,
"n_training_episodes": 50000,
"n_evaluation_episodes": 10,
"max_t": 10000,
"gamma": 0.99,
"lr": 1e-4,
"env_id": env_id,
"state_space": s_size,
"action_space": a_size,
}
```
### Train it
- We're now ready to train our agent ๐ฅ.
```python
# Create policy and place it to the device
# torch.manual_seed(50)
pixelcopter_policy = Policy(
pixelcopter_hyperparameters["state_space"],
pixelcopter_hyperparameters["action_space"],
pixelcopter_hyperparameters["h_size"],
).to(device)
pixelcopter_optimizer = optim.Adam(pixelcopter_policy.parameters(), lr=pixelcopter_hyperparameters["lr"])
```
```python
scores = reinforce(
pixelcopter_policy,
pixelcopter_optimizer,
pixelcopter_hyperparameters["n_training_episodes"],
pixelcopter_hyperparameters["max_t"],
pixelcopter_hyperparameters["gamma"],
1000,
)
```
### Publish our trained model on the Hub ๐ฅ
```python
repo_id = "" # TODO Define your repo id {username/Reinforce-{model-id}}
push_to_hub(
repo_id,
pixelcopter_policy, # The model we want to save
pixelcopter_hyperparameters, # Hyperparameters
eval_env, # Evaluation environment
video_fps=30
)
```
## Some additional challenges ๐
The best way to learn **is to try things on your own**! As you saw, the current agent is not doing great. As a first suggestion, you can train for more steps. But also try to find better parameters.
In the [Leaderboard](https://huggingface.co/spaces/huggingface-projects/Deep-Reinforcement-Learning-Leaderboard) you will find your agents. Can you get to the top?
Here are some ideas to climb up the leaderboard:
* Train more steps
* Try different hyperparameters by looking at what your classmates have done ๐ https://huggingface.co/models?other=reinforce
* **Push your new trained model** on the Hub ๐ฅ
* **Improving the implementation for more complex environments** (for instance, what about changing the network to a Convolutional Neural Network to handle
frames as observation)?
________________________________________________________________________
**Congrats on finishing this unit**!ย There was a lot of information.
And congrats on finishing the tutorial. You've just coded your first Deep Reinforcement Learning agent from scratch using PyTorch and shared it on the Hub ๐ฅณ.
Don't hesitate to iterate on this unit **by improving the implementation for more complex environments** (for instance, what about changing the network to a Convolutional Neural Network to handle
frames as observation)?
In the next unit, **we're going to learn more about Unity MLAgents**, by training agents in Unity environments. This way, you will be ready to participate in the **AI vs AI challenges where you'll train your agents
to compete against other agents in a snowball fight and a soccer game.**
Sound fun? See you next time!
Finally, we would love **to hear what you think of the course and how we can improve it**. If you have some feedback then please ๐ [fill this form](https://forms.gle/BzKXWzLAGZESGNaE9)

# Advantage Actor-Critic (A2C) [[advantage-actor-critic]]
## Reducing variance with Actor-Critic methods
The solution to reducing the variance of the Reinforce algorithm and training our agent faster and better is to use a combination of Policy-Based and Value-Based methods: *the Actor-Critic method*.
To understand the Actor-Critic, imagine you're playing a video game. You can play with a friend that will provide you with some feedback. You're the Actor and your friend is the Critic.
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/ac.jpg" alt="Actor Critic"/>
You don't know how to play at the beginning, **so you try some actions randomly**. The Critic observes your action and **provides feedback**.
Learning from this feedback, **you'll update your policy and be better at playing that game.**
On the other hand, your friend (Critic) will also update their way to provide feedback so it can be better next time.
This is the idea behind Actor-Critic. We learn two function approximations:
- *A policy* that **controls how our agent acts**: \\( \pi_{\theta}(s) \\)
- *A value function* to assist the policy update by measuring how good the action taken is: \\( \hat{q}_{w}(s,a) \\)
## The Actor-Critic Process
Now that we have seen the Actor Critic's big picture, let's dive deeper to understand how the Actor and Critic improve together during the training.
As we saw, with Actor-Critic methods, there are two function approximations (two neural networks):
- *Actor*, a **policy function** parameterized by theta: \\( \pi_{\theta}(s) \\)
- *Critic*, a **value function** parameterized by w: \\( \hat{q}_{w}(s,a) \\)
Let's see the training process to understand how the Actor and Critic are optimized:
- At each timestep, t, we get the current state \\( S_t\\) from the environment and **pass it as input through our Actor and Critic**.
- Our Policy takes the state and **outputs an action** \\( A_t \\).
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/step1.jpg" alt="Step 1 Actor Critic"/>
- The Critic takes that action also as input and, using \\( S_t\\) and \\( A_t \\), **computes the value of taking that action at that state: the Q-value**.
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/step2.jpg" alt="Step 2 Actor Critic"/>
- The action \\( A_t\\) performed in the environment outputs a new state \\( S_{t+1}\\) and a reward \\( R_{t+1} \\) .
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/step3.jpg" alt="Step 3 Actor Critic"/>
- The Actor updates its policy parameters using the Q value.
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/step4.jpg" alt="Step 4 Actor Critic"/>
- Thanks to its updated parameters, the Actor produces the next action to take at \\( A_{t+1} \\) given the new state \\( S_{t+1} \\).
- The Critic then updates its value parameters.
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/step5.jpg" alt="Step 5 Actor Critic"/>
## Adding Advantage in Actor-Critic (A2C)
We can stabilize learning further by **using the Advantage function as Critic instead of the Action value function**.
The idea is that the Advantage function calculates the relative advantage of an action compared to the others possible at a state: **how taking that action at a state is better compared to the average value of the state**. It's subtracting the mean value of the state from the state action pair:
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit8/advantage1.jpg" alt="Advantage Function"/>
In other words, this function calculates **the extra reward we get if we take this action at that state compared to the mean reward we get at that state**.
The extra reward is what's beyond the expected value of that state.
- If A(s,a) > 0: our gradient is **pushed in that direction**.
- If A(s,a) < 0 (our action does worse than the average value of that state), **our gradient is pushed in the opposite direction**.
The problem with implementing this advantage function is that it requires two value functions โ \\( Q(s,a)\\) and \\( V(s)\\). Fortunately, **we can use the TD error as a good estimator of the advantage function.**

# Conclusion
That's all for today. Congrats on finishing this Unit and the tutorial! โญ๏ธ
Now that you've successfully trained your Doom agent, why not try deathmatch? Remember, that's a much more complex level than the one you've just trained, **but it's a nice experiment and I advise you to try it.**
If you do it, don't hesitate to share your model in the `#rl-i-made-this` channel in our [discord server](https://www.hf.co/join/discord).
This concludes the last unit, but we are not finished yet! ๐ค The following **bonus unit includes some of the most interesting, advanced, and cutting edge work in Deep Reinforcement Learning**.
See you next time ๐ฅ
## Keep Learning, Stay awesome ๐ค

# (Automatic) Curriculum Learning for RL
While most of the RL methods seen in this course work well in practice, there are some cases where using them alone fails. This can happen, for instance, when:
- the task to learn is hard and requires an **incremental acquisition of skills** (for instance when one wants to make a bipedal agent learn to go through hard obstacles, it must first learn to stand, then walk, then maybe jumpโฆ)
- there are variations in the environment (that affect the difficulty) and one wants its agent to be **robust** to them

</figure>
In such cases, it seems needed to propose different tasks to our RL agent and organize them such that the agent progressively acquires skills. This approach is called **Curriculum Learning** and usually implies a hand-designed curriculum (or set of tasks organized in a specific order). In practice, one can, for instance, control the generation of the environment, the initial states, or use Self-Play and control the level of opponents proposed to the RL agent.
As designing such a curriculum is not always trivial, the field of **Automatic Curriculum Learning (ACL) proposes to design approaches that learn to create such an organization of tasks in order to maximize the RL agentโs performances**. Portelas et al. proposed to define ACL as:
> โฆ a family of mechanisms that automatically adapt the distribution of training data by learning to adjust the selection of learning situations to the capabilities of RL agents.
>
As an example, OpenAI used **Domain Randomization** (they applied random variations on the environment) to make a robot hand solve Rubikโs Cubes.

Finally, you can play with the robustness of agents trained in the <a href="https://huggingface.co/spaces/flowers-team/Interactive_DeepRL_Demo">TeachMyAgent</a> benchmark by controlling environment variations or even drawing the terrain ๐

# Introduction:
<img src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit13/thumbnail.png" alt="Unit bonus 4 thumbnail"/>
Welcome to this bonus unit, where you will **train a robot agent to complete a mini-game level using imitation learning.**
At the end of the unit, **you will have a trained agent capable of solving the level as in the video**:
<video src="https://huggingface.co/datasets/huggingface-deep-rl-course/course-images/resolve/main/en/unit13/onnx_inference_test.mp4" type="video/mp4" controls autoplay loop mute />
## Objectives:
- Learn how to use imitation learning with Godot RL Agents by training an agent to complete a mini-game environment using human-recorded expert demonstrations.
## Prerequisites and requirements:
- It is recommended that you complete the previous chapter ([Godot RL Agents](https://huggingface.co/learn/deep-rl-course/unitbonus3/godotrl)) before starting this tutorial,
- Some familiarity with Godot is recommended, although completing the tutorial does not require any gdscript coding knowledge,
- Godot with .NET support (tested to work with [4.3.dev5 .NET](https://godotengine.org/article/dev-snapshot-godot-4-3-dev-5/), may work with newer versions too),
- Godot RL Agents (you can use `pip install godot-rl` in the venv/conda env),
- [Imitation library](https://huggingface.co/learn/deep-rl-course/unitbonus5/train-our-robot),
- Time: ~1-2 hours to complete the project and training. It can be outside of this range depending on the hardware used.
