=====
|

+
|
| 28 |
+
Let `y(n)` be the recurrence of given type, ``c`` be the sequence
|
| 29 |
+
of coefficients, ``b`` be the sequence of initial/base values of the
|
| 30 |
+
recurrence and ``k`` (equal to ``len(c)``) be the order of recurrence.
|
| 31 |
+
Then,
|
| 32 |
+
|
| 33 |
+
.. math :: y(n) = \begin{cases} b_n & 0 \le n < k \\
|
| 34 |
+
c_0 y(n-1) + c_1 y(n-2) + \cdots + c_{k-1} y(n-k) & n \ge k
|
| 35 |
+
\end{cases}
|
| 36 |
+
|
| 37 |
+
Let `x_0, x_1, \ldots, x_n` be a sequence and consider the transformation
|
| 38 |
+
that maps each polynomial `f(x)` to `T(f(x))` where each power `x^i` is
|
| 39 |
+
replaced by the corresponding value `x_i`. The sequence is then a solution
|
| 40 |
+
of the recurrence if and only if `T(x^i p(x)) = 0` for each `i \ge 0` where
|
| 41 |
+
`p(x) = x^k - c_0 x^(k-1) - \cdots - c_{k-1}` is the characteristic
|
| 42 |
+
polynomial.
|
| 43 |
+
|
| 44 |
+
Then `T(f(x)p(x)) = 0` for each polynomial `f(x)` (as it is a linear
|
| 45 |
+
combination of powers `x^i`). Now, if `x^n` is congruent to
|
| 46 |
+
`g(x) = a_0 x^0 + a_1 x^1 + \cdots + a_{k-1} x^{k-1}` modulo `p(x)`, then
|
| 47 |
+
`T(x^n) = x_n` is equal to
|
| 48 |
+
`T(g(x)) = a_0 x_0 + a_1 x_1 + \cdots + a_{k-1} x_{k-1}`.
|
| 49 |
+
|
| 50 |
+
Computation of `x^n`,
|
| 51 |
+
given `x^k = c_0 x^{k-1} + c_1 x^{k-2} + \cdots + c_{k-1}`
|
| 52 |
+
is performed using exponentiation by squaring (refer to [1_]) with
|
| 53 |
+
an additional reduction step performed to retain only first `k` powers
|
| 54 |
+
of `x` in the representation of `x^n`.

|
| 31 |
+
|

|
| 32 |
+
Instantiate a [`AutoencoderKL`] from pretrained ControlNet weights saved in the original `.ckpt` or
|
| 33 |
+
`.safetensors` format. The pipeline is set in evaluation mode (`model.eval()`) by default.
|
| 34 |
+
|
| 35 |
+
Parameters:
|
| 36 |
+
pretrained_model_link_or_path (`str` or `os.PathLike`, *optional*):
|
| 37 |
+
Can be either:
|
| 38 |
+
- A link to the `.ckpt` file (for example
|
| 39 |
+
`"https://huggingface.co/<repo_id>/blob/main/<path_to_file>.ckpt"`) on the Hub.
|
| 40 |
+
- A path to a *file* containing all pipeline weights.
|
| 41 |
+
config_file (`str`, *optional*):
|
| 42 |
+
Filepath to the configuration YAML file associated with the model. If not provided it will default to:
|
| 43 |
+
https://raw.githubusercontent.com/CompVis/stable-diffusion/main/configs/stable-diffusion/v1-inference.yaml
|
| 44 |
+
torch_dtype (`str` or `torch.dtype`, *optional*):
|
| 45 |
+
Override the default `torch.dtype` and load the model with another dtype. If `"auto"` is passed, the
|
| 46 |
+
dtype is automatically derived from the model's weights.
|
| 47 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 48 |
+
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
|
| 49 |
+
cached versions if they exist.
|
| 50 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 51 |
+
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
|
| 52 |
+
is not used.
|
| 53 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 54 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
|
| 55 |
+
incompletely downloaded files are deleted.
|
| 56 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 57 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 58 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 59 |
+
local_files_only (`bool`, *optional*, defaults to `False`):
|
| 60 |
+
Whether to only load local model weights and configuration files or not. If set to True, the model
|
| 61 |
+
won't be downloaded from the Hub.
|
| 62 |
+
token (`str` or *bool*, *optional*):
|
| 63 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from
|
| 64 |
+
`diffusers-cli login` (stored in `~/.huggingface`) is used.
|
| 65 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 66 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 67 |
+
allowed by Git.
|
| 68 |
+
image_size (`int`, *optional*, defaults to 512):
|
| 69 |
+
The image size the model was trained on. Use 512 for all Stable Diffusion v1 models and the Stable
|
| 70 |
+
Diffusion v2 base model. Use 768 for Stable Diffusion v2.
|
| 71 |
+
scaling_factor (`float`, *optional*, defaults to 0.18215):
|
| 72 |
+
The component-wise standard deviation of the trained latent space computed using the first batch of the
|
| 73 |
+
training set. This is used to scale the latent space to have unit variance when training the diffusion
|
| 74 |
+
model. The latents are scaled with the formula `z = z * scaling_factor` before being passed to the
|
| 75 |
+
diffusion model. When decoding, the latents are scaled back to the original scale with the formula: `z
|
| 76 |
+
= 1 / scaling_factor * z`. For more details, refer to sections 4.3.2 and D.1 of the [High-Resolution
|
| 77 |
+
Image Synthesis with Latent Diffusion Models](https://arxiv.org/abs/2112.10752) paper.
|
| 78 |
+
kwargs (remaining dictionary of keyword arguments, *optional*):
|
| 79 |
+
Can be used to overwrite load and saveable variables (for example the pipeline components of the
|
| 80 |
+
specific pipeline class). The overwritten components are directly passed to the pipelines `__init__`
|
| 81 |
+
method. See example below for more information.
|
| 82 |
+
|
| 83 |
+
<Tip warning={true}>
|
| 84 |
+
|
| 85 |
+
Make sure to pass both `image_size` and `scaling_factor` to `from_single_file()` if you're loading
|
| 86 |
+
a VAE from SDXL or a Stable Diffusion v2 model or higher.
|

r"""
|
| 32 |
+
Instantiate a [`ControlNetModel`] from pretrained ControlNet weights saved in the original `.ckpt` or
|
| 33 |
+
`.safetensors` format. The pipeline is set in evaluation mode (`model.eval()`) by default.
|
| 34 |
+
|
| 35 |
+
Parameters:
|
| 36 |
+
pretrained_model_link_or_path (`str` or `os.PathLike`, *optional*):
|
| 37 |
+
Can be either:
|
| 38 |
+
- A link to the `.ckpt` file (for example
|
| 39 |
+
`"https://huggingface.co/<repo_id>/blob/main/<path_to_file>.ckpt"`) on the Hub.
|
| 40 |
+
- A path to a *file* containing all pipeline weights.
|
| 41 |
+
config_file (`str`, *optional*):
|
| 42 |
+
Filepath to the configuration YAML file associated with the model. If not provided it will default to:
|
| 43 |
+
https://raw.githubusercontent.com/lllyasviel/ControlNet/main/models/cldm_v15.yaml
|
| 44 |
+
torch_dtype (`str` or `torch.dtype`, *optional*):
|
| 45 |
+
Override the default `torch.dtype` and load the model with another dtype. If `"auto"` is passed, the
|
| 46 |
+
dtype is automatically derived from the model's weights.
|
| 47 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 48 |
+
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
|
| 49 |
+
cached versions if they exist.
|
| 50 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 51 |
+
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
|
| 52 |
+
is not used.
|
| 53 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 54 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
|
| 55 |
+
incompletely downloaded files are deleted.
|
| 56 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 57 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 58 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 59 |
+
local_files_only (`bool`, *optional*, defaults to `False`):
|
| 60 |
+
Whether to only load local model weights and configuration files or not. If set to True, the model
|
| 61 |
+
won't be downloaded from the Hub.
|
| 62 |
+
token (`str` or *bool*, *optional*):
|
| 63 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from
|
| 64 |
+
`diffusers-cli login` (stored in `~/.huggingface`) is used.
|
| 65 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 66 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 67 |
+
allowed by Git.
|
| 68 |
+
image_size (`int`, *optional*, defaults to 512):
|
| 69 |
+
The image size the model was trained on. Use 512 for all Stable Diffusion v1 models and the Stable
|
| 70 |
+
Diffusion v2 base model. Use 768 for Stable Diffusion v2.
|
| 71 |
+
upcast_attention (`bool`, *optional*, defaults to `None`):
|
| 72 |
+
Whether the attention computation should always be upcasted.
|
| 73 |
+
kwargs (remaining dictionary of keyword arguments, *optional*):
|
| 74 |
+
Can be used to overwrite load and saveable variables (for example the pipeline components of the
|
| 75 |
+
specific pipeline class). The overwritten components are directly passed to the pipelines `__init__`
|
| 76 |
+
method. See example below for more information.

| 62 |
+
|
| 63 |
+
- A string, the *model id* (for example `google/ddpm-celebahq-256`) of a pretrained model hosted on
|
| 64 |
+
the Hub.
|
| 65 |
+
- A path to a *directory* (for example `./my_model_directory`) containing the model weights saved
|
| 66 |
+
with [`ModelMixin.save_pretrained`].
|
| 67 |
+
- A [torch state
|

dict](https://pytorch.org/tutorials/beginner/saving_loading_models.html#what-is-a-state-dict).
|
| 69 |
+
subfolder (`str` or `List[str]`):
|
| 70 |
+
The subfolder location of a model file within a larger model repository on the Hub or locally.
|
| 71 |

If a list is passed, it should have the same length as `weight_name`.
|
| 72 |
+
weight_name (`str` or `List[str]`):
|
| 73 |

image_encoder_folder (`str`, *optional*, defaults to `image_encoder`):
|
| 76 |
+
The subfolder location of the image encoder within a larger model repository on the Hub or locally.
|
| 77 |
+
Pass `None` to not load the image encoder. If the image encoder is located in a folder inside `subfolder`,
|
| 78 |
+
you only need to pass the name of the folder that contains image encoder weights, e.g. `image_encoder_folder="image_encoder"`.
|
| 79 |
+
If the image encoder is located in a folder other than `subfolder`, you should pass the path to the folder that contains image encoder weights,
|
| 80 |
+
for example, `image_encoder_folder="different_subfolder/image_encoder"`.
|
| 81 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 82 |

is not used.
|
| 84 |

Parameters:
|
| 161 |
+
pretrained_model_name_or_path_or_dict (`str` or `os.PathLike` or `dict`):
|
| 162 |
+
Can be either:
|
| 163 |
+
|
| 164 |
+
- A string, the *model id* (for example `google/ddpm-celebahq-256`) of a pretrained model hosted on
|
| 165 |
+
the Hub.
|
| 166 |
+
- A path to a *directory* (for example `./my_model_directory`) containing the model weights saved
|
| 167 |
+
with [`ModelMixin.save_pretrained`].
|
| 168 |
+
- A [torch state
|
| 169 |
+
dict](https://pytorch.org/tutorials/beginner/saving_loading_models.html#what-is-a-state-dict).
|
| 170 |
+
|
| 171 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 172 |
+
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
|
| 173 |
+
is not used.
|
| 174 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 175 |
+
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
|
| 176 |
+
cached versions if they exist.
|
| 177 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 178 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
|
| 179 |
+
incompletely downloaded files are deleted.
|
| 180 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 181 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 182 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 183 |
+
local_files_only (`bool`, *optional*, defaults to `False`):
|
| 184 |
+
Whether to only load local model weights and configuration files or not. If set to `True`, the model
|
| 185 |
+
won't be downloaded from the Hub.
|
| 186 |
+
token (`str` or *bool*, *optional*):
|
| 187 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from
|
| 188 |
+
`diffusers-cli login` (stored in `~/.huggingface`) is used.
|
| 189 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 190 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 191 |
+
allowed by Git.
|
| 192 |
+
subfolder (`str`, *optional*, defaults to `""`):
|
| 193 |
+
The subfolder location of a model file within a larger model repository on the Hub or locally.
|
| 194 |
+
low_cpu_mem_usage (`bool`, *optional*, defaults to `True` if torch version >= 1.9.0 else `False`):
|
| 195 |
+
Speed up model loading only loading the pretrained weights and not initializing the weights. This also
|
| 196 |
+
tries to not use more than 1x model size in CPU memory (including peak memory) while loading the model.
|
| 197 |
+
Only supported for PyTorch >= 1.9.0. If you are using an older version of PyTorch, setting this
|
| 198 |
+
argument to `True` will raise an error.
|
| 199 |
+
mirror (`str`, *optional*):
|
| 200 |
+
Mirror source to resolve accessibility issues if you're downloading a model in China. We do not
|
| 201 |
+
guarantee the timeliness or safety of the source, and you should refer to the mirror site for more
|
| 202 |

Directory to save LoRA parameters to. Will be created if it doesn't exist.
|
| 1295 |
+
unet_lora_layers (`Dict[str, torch.nn.Module]` or `Dict[str, torch.Tensor]`):
|

+
State dict of the LoRA layers corresponding to the `unet`.
|
| 1297 |
+
text_encoder_lora_layers (`Dict[str, torch.nn.Module]` or `Dict[str, torch.Tensor]`):
|
| 1298 |
+
State dict of the LoRA layers corresponding to the `text_encoder`. Must explicitly pass the text
|
| 1299 |
+
encoder LoRA state dict because it comes from 🤗 Transformers.
|
| 1300 |
+
is_main_process (`bool`, *optional*, defaults to `True`):
|
| 1301 |
+
Whether the process calling this is the main process or not. Useful during distributed training and you
|
| 1302 |
+
need to call this function on all processes. In this case, set `is_main_process=True` only on the main
|
| 1303 |
+
process to avoid race conditions.
|
| 1304 |
+
save_function (`Callable`):
|
| 1305 |
+
The function to use to save the state dictionary. Useful during distributed training when you need to
|
| 1306 |
+
replace `torch.save` with another method. Can be configured with the environment variable
|
| 1307 |
+
`DIFFUSERS_SAVE_MODE`.
|
| 1308 |
+
safe_serialization (`bool`, *optional*, defaults to `True`):
|

r"""
|
| 163 |
+
Instantiate a [`DiffusionPipeline`] from pretrained pipeline weights saved in the `.ckpt` or `.safetensors`
|
| 164 |
+
format. The pipeline is set in evaluation mode (`model.eval()`) by default.
|
| 165 |
+
|
| 166 |
+
Parameters:
|
| 167 |
+
pretrained_model_link_or_path (`str` or `os.PathLike`, *optional*):
|
| 168 |
+
Can be either:
|
| 169 |
+
- A link to the `.ckpt` file (for example
|
| 170 |
+
`"https://huggingface.co/<repo_id>/blob/main/<path_to_file>.ckpt"`) on the Hub.
|
| 171 |
+
- A path to a *file* containing all pipeline weights.
|
| 172 |
+
torch_dtype (`str` or `torch.dtype`, *optional*):
|
| 173 |
+
Override the default `torch.dtype` and load the model with another dtype.
|
| 174 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 175 |
+
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
|
| 176 |
+
cached versions if they exist.
|
| 177 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 178 |
+
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
|
| 179 |
+
is not used.
|
| 180 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 181 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
|
| 182 |
+
incompletely downloaded files are deleted.
|
| 183 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 184 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 185 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 186 |
+
local_files_only (`bool`, *optional*, defaults to `False`):
|
| 187 |
+
Whether to only load local model weights and configuration files or not. If set to `True`, the model
|
| 188 |
+
won't be downloaded from the Hub.
|
| 189 |
+
token (`str` or *bool*, *optional*):
|
| 190 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from
|
| 191 |
+
`diffusers-cli login` (stored in `~/.huggingface`) is used.
|
| 192 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 193 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 194 |
+
allowed by Git.
|
| 195 |
+
original_config_file (`str`, *optional*):
|
| 196 |
+
The path to the original config file that was used to train the model. If not provided, the config file
|
| 197 |
+
will be inferred from the checkpoint file.
|
| 198 |
+
model_type (`str`, *optional*):
|
| 199 |
+
The type of model to load. If not provided, the model type will be inferred from the checkpoint file.
|
| 200 |
+
image_size (`int`, *optional*):
|
| 201 |
+
The size of the image output. It's used to configure the `sample_size` parameter of the UNet and VAE model.
|
| 202 |
+
load_safety_checker (`bool`, *optional*, defaults to `False`):
|
| 203 |
+
Whether to load the safety checker model or not. By default, the safety checker is not loaded unless a `safety_checker` component is passed to the `kwargs`.
|
| 204 |
+
num_in_channels (`int`, *optional*):
|
| 205 |
+
Specify the number of input channels for the UNet model. Read more about how to configure UNet model with this parameter
|
| 206 |
+
[here](https://huggingface.co/docs/diffusers/training/adapt_a_model#configure-unet2dconditionmodel-parameters).
|
| 207 |
+
scaling_factor (`float`, *optional*):
|
| 208 |
+
The scaling factor to use for the VAE model. If not provided, it is inferred from the config file first.
|
| 209 |
+
If the scaling factor is not found in the config file, the default value 0.18215 is used.
|
| 210 |
+
scheduler_type (`str`, *optional*):
|
| 211 |
+
The type of scheduler to load. If not provided, the scheduler type will be inferred from the checkpoint file.
|
| 212 |
+
prediction_type (`str`, *optional*):
|
| 213 |
+
The type of prediction to load. If not provided, the prediction type will be inferred from the checkpoint file.
|
| 214 |
+
kwargs (remaining dictionary of keyword arguments, *optional*):
|
| 215 |
+
Can be used to overwrite load and saveable variables (the pipeline components of the specific pipeline
|
| 216 |
+
class). The overwritten components are passed directly to the pipelines `__init__` method. See example
|
| 217 |
+
below for more information.

|
| 290 |
+
token (`str` or `List[str]`, *optional*):
|
| 291 |
+
Override the token to use for the textual inversion weights. If `pretrained_model_name_or_path` is a

| 292 |
+
list, then `token` must also be a list of equal length.
|
| 293 |
+
text_encoder ([`~transformers.CLIPTextModel`], *optional*):
|
| 294 |
+
Frozen text-encoder ([clip-vit-large-patch14](https://huggingface.co/openai/clip-vit-large-patch14)).

+
Name of a custom weight file. This should be used when:
|
| 300 |
+
|
| 301 |
+
- The saved textual inversion file is in 🤗 Diffusers format, but was saved under a specific weight
|
| 302 |

+
- The saved textual inversion file is in the Automatic1111 format.
|
| 304 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):

+
is not used.
|
| 307 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 308 |

|
| 316 |
+
local_files_only (`bool`, *optional*, defaults to `False`):
|
| 317 |
+
Whether to only load local model weights and configuration files or not. If set to `True`, the model

won't be downloaded from the Hub.
|
| 319 |
+
token (`str` or *bool*, *optional*):
|
| 320 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from

+
|
| 336 |
+

| 337 |
+

| 346 |
+
|

"""

The [`ControlNetModel`] forward method.
|

+
|

+
Args:
|
| 682 |
+
sample (`torch.FloatTensor`):
|
| 683 |
+
The noisy input tensor.
|
| 684 |
+
timestep (`Union[torch.Tensor, float, int]`):
|
| 685 |
+
The number of timesteps to denoise an input.
|
| 686 |
+
encoder_hidden_states (`torch.Tensor`):
|
| 687 |
+
The encoder hidden states.
|
| 688 |
+
controlnet_cond (`torch.FloatTensor`):
|
| 689 |
+
The conditional input tensor of shape `(batch_size, sequence_length, hidden_size)`.
|
| 690 |
+
conditioning_scale (`float`, defaults to `1.0`):
|
| 691 |
+
The scale factor for ControlNet outputs.
|
| 692 |
+
class_labels (`torch.Tensor`, *optional*, defaults to `None`):
|
| 693 |
+
Optional class labels for conditioning. Their embeddings will be summed with the timestep embeddings.
|
| 694 |
+
timestep_cond (`torch.Tensor`, *optional*, defaults to `None`):
|
| 695 |
+
Additional conditional embeddings for timestep. If provided, the embeddings will be summed with the
|
| 696 |
+
timestep_embedding passed through the `self.time_embedding` layer to obtain the final timestep
|
| 697 |
+
embeddings.
|
| 698 |
+
attention_mask (`torch.Tensor`, *optional*, defaults to `None`):
|
| 699 |
+
An attention mask of shape `(batch, key_tokens)` is applied to `encoder_hidden_states`. If `1` the mask
|
| 700 |
+
is kept, otherwise if `0` it is discarded. Mask will be converted into a bias, which adds large
|
| 701 |
+
negative values to the attention scores corresponding to "discard" tokens.
|
| 702 |
+
added_cond_kwargs (`dict`):
|
| 703 |
+
Additional conditions for the Stable Diffusion XL UNet.
|
| 704 |
+
cross_attention_kwargs (`dict[str]`, *optional*, defaults to `None`):
|
| 705 |
+
A kwargs dictionary that if specified is passed along to the `AttnProcessor`.
|
| 706 |
+
guess_mode (`bool`, defaults to `False`):
|
| 707 |
+
In this mode, the ControlNet encoder tries its best to recognize the input content of the input even if
|
| 708 |
+
you remove all prompts. A `guidance_scale` between 3.0 and 5.0 is recommended.
|
| 709 |
+
return_dict (`bool`, defaults to `True`):
|
| 710 |
+
Whether or not to return a [`~models.controlnet.ControlNetOutput`] instead of a plain tuple.
|
| 711 |
+
|
| 712 |
+
Returns:
|
| 713 |
+
[`~models.controlnet.ControlNetOutput`] **or** `tuple`:
|
| 714 |
+
If `return_dict` is `True`, a [`~models.controlnet.ControlNetOutput`] is returned, otherwise a tuple is
|
| 715 |
+
returned where the first element is the sample tensor.

subclass. Use it as a regular Flax Linen module and refer to the Flax documentation for all matters related to its
|
| 113 |
+
general usage and behavior.
|
| 114 |

Cast the floating-point `params` to `jax.numpy.bfloat16`. This returns a new `params` tree and does not cast
|
| 98 |

the `params` in place.

This method can be used on a TPU to explicitly convert the model parameters to bfloat16 precision to do full
|
| 101 |
+
half-precision training or to save weights in bfloat16 for inference in order to save memory and improve speed.

A `PyTree` of model parameters.
|
| 106 |

mask (`Union[Dict, FrozenDict]`):
|
| 107 |
+
A `PyTree` with same structure as the `params` tree. The leaves should be booleans. It should be `True`
|

+
for params you want to cast, and `False` for those you want to skip.

Instantiate a pretrained Flax model from a pretrained model configuration.

| 215 |
+
Parameters:
|
| 216 |
+
pretrained_model_name_or_path (`str` or `os.PathLike`):
|
| 217 |
+
Can be either:
|
| 218 |
+
|
| 219 |
+
- A string, the *model id* (for example `runwayml/stable-diffusion-v1-5`) of a pretrained model
|
| 220 |
+
hosted on the Hub.
|
| 221 |
+
- A path to a *directory* (for example `./my_model_directory`) containing the model weights saved
|
| 222 |
+
using [`~FlaxModelMixin.save_pretrained`].
|
| 223 |
+
dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
|
| 224 |
+
The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
|
| 225 |
+
`jax.numpy.bfloat16` (on TPUs).
|
| 226 |
+
|
| 227 |
+
This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
|
| 228 |
+
specified, all the computation will be performed with the given `dtype`.
|
| 229 |
+
|
| 230 |
+
<Tip>
|
| 231 |
+
|
| 232 |
+
This only specifies the dtype of the *computation* and does not influence the dtype of model
|
| 233 |
+
parameters.
|
| 234 |
+
|
| 235 |
+
If you wish to change the dtype of the model parameters, see [`~FlaxModelMixin.to_fp16`] and
|
| 236 |
+
[`~FlaxModelMixin.to_bf16`].
|
| 237 |
+
|
| 238 |
+
</Tip>
|
| 239 |
+
|
| 240 |
+
model_args (sequence of positional arguments, *optional*):
|
| 241 |
+
All remaining positional arguments are passed to the underlying model's `__init__` method.
|
| 242 |
+
cache_dir (`Union[str, os.PathLike]`, *optional*):
|
| 243 |
+
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
|
| 244 |
+
is not used.
|
| 245 |
+
force_download (`bool`, *optional*, defaults to `False`):
|
| 246 |
+
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
|
| 247 |
+
cached versions if they exist.
|
| 248 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 249 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
|
| 250 |
+
incompletely downloaded files are deleted.
|
| 251 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 252 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 253 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 254 |
+
local_files_only(`bool`, *optional*, defaults to `False`):
|
| 255 |
+
Whether to only load local model weights and configuration files or not. If set to `True`, the model
|
| 256 |
+
won't be downloaded from the Hub.
|
| 257 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 258 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 259 |
+
allowed by Git.
|
| 260 |
+
from_pt (`bool`, *optional*, defaults to `False`):
|
| 261 |
+
Load the model weights from a PyTorch checkpoint save file.
|
| 262 |
+
kwargs (remaining dictionary of keyword arguments, *optional*):
|
| 263 |
+
Can be used to update the configuration object (after it is loaded) and initiate the model (for
|
| 264 |
+
example, `output_attentions=True`). Behaves differently depending on whether a `config` is provided or
|
| 265 |
+
automatically loaded:
|
| 266 |
+
|
| 267 |
+
- If a configuration is provided with `config`, `kwargs` are directly passed to the underlying
|
| 268 |
+
model's `__init__` method (we assume all relevant updates to the configuration have already been
|
| 269 |
+
done).
|
| 270 |
+
- If a configuration is not provided, `kwargs` are first passed to the configuration class
|
| 271 |
+
initialization function [`~ConfigMixin.from_config`]. Each key of the `kwargs` that corresponds
|
| 272 |
+
to a configuration attribute is used to override said attribute with the supplied `kwargs` value.
|
| 273 |
+
Remaining keys that do not correspond to any configuration attribute are passed to the underlying
|
| 274 |
+
model's `__init__` function.
|
| 275 |
+
|
| 276 |
+
Examples:
|
| 277 |
+
|
| 278 |
+
```python
|
| 279 |
+
>>> from diffusers import FlaxUNet2DConditionModel
|
| 280 |
+
|
| 281 |
+
>>> # Download model and configuration from huggingface.co and cache.
|
| 282 |
+
>>> model, params = FlaxUNet2DConditionModel.from_pretrained("runwayml/stable-diffusion-v1-5")
|
| 283 |
+
>>> # Model was saved using *save_pretrained('./test/saved_model/')* (for example purposes, not runnable).
|
| 284 |
+
>>> model, params = FlaxUNet2DConditionModel.from_pretrained("./test/saved_model/")
|
| 285 |
+
```
|
| 286 |
+
|
| 287 |
+
If you get the error message below, you need to finetune the weights for your downstream task:
|
| 288 |
+
|
| 289 |
+
```bash
|
| 290 |
+
Some weights of UNet2DConditionModel were not initialized from the model checkpoint at runwayml/stable-diffusion-v1-5 and are newly initialized because the shapes did not match:
|
| 291 |
+
- conv_in.weight: found shape torch.Size([320, 4, 3, 3]) in the checkpoint and torch.Size([320, 9, 3, 3]) in the model instantiated
|
| 292 |
+
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

|
| 406 |
+
- A path to a *directory* (for example `./my_model_directory`) containing the model weights saved

|
| 412 |
+
torch_dtype (`str` or `torch.dtype`, *optional*):

|
| 418 |
+
resume_download (`bool`, *optional*, defaults to `False`):
|
| 419 |
+
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any

+
incompletely downloaded files are deleted.
|
| 421 |
+
proxies (`Dict[str, str]`, *optional*):
|
| 422 |
+
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
|
| 423 |
+
'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
|
| 424 |

output_loading_info (`bool`, *optional*, defaults to `False`):
|
| 425 |
+
Whether or not to also return a dictionary containing missing keys, unexpected keys and error messages.
|
| 426 |
+
local_files_only(`bool`, *optional*, defaults to `False`):
|
| 427 |
+
Whether to only load local model weights and configuration files or not. If set to `True`, the model
|
| 428 |
+
won't be downloaded from the Hub.
|
| 429 |
+
token (`str` or *bool*, *optional*):
|
| 430 |
+
The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from

|
| 432 |
+
revision (`str`, *optional*, defaults to `"main"`):
|
| 433 |
+
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
|
| 434 |
+
allowed by Git.
|
| 435 |
+
from_flax (`bool`, *optional*, defaults to `False`):
|
| 436 |
+
Load the model weights from a Flax checkpoint save file.
|
| 437 |
+
subfolder (`str`, *optional*, defaults to `""`):
|
| 438 |
+
The subfolder location of a model file within a larger model repository on the Hub or locally.
|
| 439 |
+
mirror (`str`, *optional*):
|
| 440 |
+
Mirror source to resolve accessibility issues if you're downloading a model in China. We do not
|
| 441 |
+
guarantee the timeliness or safety of the source, and you should refer to the mirror site for more
|
| 442 |
+
information.
|
| 443 |
+
device_map (`str` or `Dict[str, Union[int, str, torch.device]]`, *optional*):
|
| 444 |
+
A map that specifies where each submodule should go. It doesn't need to be defined for each
|
| 445 |
+
parameter/buffer name; once a given module name is inside, every submodule of it will be sent to the
|
| 446 |
+
same device.
|
| 447 |
+
|
| 448 |
+
Set `device_map="auto"` to have 🤗 Accelerate automatically compute the most optimized `device_map`. For
|
| 449 |
+
more information about each option see [designing a device
|
| 450 |
+
map](https://hf.co/docs/accelerate/main/en/usage_guides/big_modeling#designing-a-device-map).
|
| 451 |
+
max_memory (`Dict`, *optional*):
|
| 452 |
+
A dictionary device identifier for the maximum memory. Will default to the maximum memory available for
|
| 453 |

+
offload_folder (`str` or `os.PathLike`, *optional*):
|
| 455 |
+
The path to offload weights if `device_map` contains the value `"disk"`.
|
| 456 |
+
offload_state_dict (`bool`, *optional*):
|
| 457 |
+
If `True`, temporarily offloads the CPU state dict to the hard drive to avoid running out of CPU RAM if
|
| 458 |
+
the weight of the CPU state dict + the biggest shard of the checkpoint does not fit. Defaults to `True`
|
| 459 |
+
when there is some disk offload.
|
| 460 |
+
low_cpu_mem_usage (`bool`, *optional*, defaults to `True` if torch version >= 1.9.0 else `False`):
|
| 461 |
+
Speed up model loading only loading the pretrained weights and not initializing the weights. This also
|
| 462 |
+
tries to not use more than 1x model size in CPU memory (including peak memory) while loading the model.
|
| 463 |
+
Only supported for PyTorch >= 1.9.0. If you are using an older version of PyTorch, setting this
|
| 464 |
+
argument to `True` will raise an error.
|
| 465 |
+
variant (`str`, *optional*):
|
| 466 |
+
Load weights from a specified `variant` filename such as `"fp16"` or `"ema"`. This is ignored when
|
| 467 |
+
loading `from_flax`.
|
| 468 |
+
use_safetensors (`bool`, *optional*, defaults to `None`):
|
| 469 |
+
If set to `None`, the `safetensors` weights are downloaded if they're available **and** if the
|
| 470 |
+
`safetensors` library is installed. If set to `True`, the model is forcibly loaded from `safetensors`
|
| 471 |
+
weights. If set to `False`, `safetensors` weights are not loaded.
|
| 472 |
+
|
| 473 |
+
<Tip>
|
| 474 |
+
|
| 475 |
+
To use private or [gated models](https://huggingface.co/docs/hub/models-gated#gated-models), log-in with
|
| 476 |
+
`huggingface-cli login`. You can also activate the special
|
| 477 |
+
["offline-mode"](https://huggingface.co/diffusers/installation.html#offline-mode) to use this method in a
|
| 478 |
+
firewalled environment.
|
| 479 |
+
|
| 480 |
+
</Tip>
|
| 481 |
+
|
| 482 |
+
Example:
|
| 483 |
+
|
| 484 |
+
```py
|
| 485 |
+
from diffusers import UNet2DConditionModel
|
| 486 |
+
|
| 487 |
+
unet = UNet2DConditionModel.from_pretrained("runwayml/stable-diffusion-v1-5", subfolder="unet")
|
| 488 |
+
```
|
| 489 |
+
|
| 490 |
+
If you get the error message below, you need to finetune the weights for your downstream task:
|
| 491 |
+
|
| 492 |
+
```bash
|
| 493 |
+
Some weights of UNet2DConditionModel were not initialized from the model checkpoint at runwayml/stable-diffusion-v1-5 and are newly initialized because the shapes did not match:
|
| 494 |
+
- conv_in.weight: found shape torch.Size([320, 4, 3, 3]) in the checkpoint and torch.Size([320, 9, 3, 3]) in the model instantiated
|
| 495 |
+
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.
|
| 496 |
+
