| Instantiates a text-to-image Pytorch diffusion pipeline from pretrained pipeline weight. |
| |
| The from_pretrained() method takes care of returning the correct pipeline class instance by: |
| 1. Detect the pipeline class of the pretrained_model_or_path based on the _class_name property of its |
| config object |
| 2. Find the text-to-image pipeline linked to the pipeline class using pattern matching on pipeline class |
| name. |
| |
| If a `controlnet` argument is passed, it will instantiate a [`StableDiffusionControlNetPipeline`] object. |
| |
| The pipeline is set in evaluation mode (`model.eval()`) by default. |
| |
| If you get the error message below, you need to finetune the weights for your downstream task: |
| |
| ``` |
| 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: |
| - 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 |
| You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference. |
| ``` |
| |
| Parameters: |
| pretrained_model_name_or_path (`str` or `os.PathLike`, *optional*): |
| Can be either: |
| |
| - A string, the *repo id* (for example `CompVis/ldm-text2im-large-256`) of a pretrained pipeline |
| hosted on the Hub. |
| - A path to a *directory* (for example `./my_pipeline_directory/`) containing pipeline weights |
| saved using |
| [`~DiffusionPipeline.save_pretrained`]. |
| torch_dtype (`str` or `torch.dtype`, *optional*): |
| Override the default `torch.dtype` and load the model with another dtype. If "auto" is passed, the |
| dtype is automatically derived from the model's weights. |
| force_download (`bool`, *optional*, defaults to `False`): |
| Whether or not to force the (re-)download of the model weights and configuration files, overriding the |
| cached versions if they exist. |
| cache_dir (`Union[str, os.PathLike]`, *optional*): |
| Path to a directory where a downloaded pretrained model configuration is cached if the standard cache |
| is not used. |
| resume_download (`bool`, *optional*, defaults to `False`): |
| Whether or not to resume downloading the model weights and configuration files. If set to `False`, any |
| incompletely downloaded files are deleted. |
| proxies (`Dict[str, str]`, *optional*): |
| A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128', |
| 'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request. |
| output_loading_info(`bool`, *optional*, defaults to `False`): |
| Whether or not to also return a dictionary containing missing keys, unexpected keys and error messages. |
| local_files_only (`bool`, *optional*, defaults to `False`): |
| 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. |
| use_auth_token (`str` or *bool*, *optional*): |
| The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from |
| `diffusers-cli login` (stored in `~/.huggingface`) is used. |
| revision (`str`, *optional*, defaults to `"main"`): |
| The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier |
| allowed by Git. |
| custom_revision (`str`, *optional*, defaults to `"main"`): |
| The specific model version to use. It can be a branch name, a tag name, or a commit id similar to |
| `revision` when loading a custom pipeline from the Hub. It can be a 🤗 Diffusers version when loading a |
| custom pipeline from GitHub, otherwise it defaults to `"main"` when loading from the Hub. |
| mirror (`str`, *optional*): |
| Mirror source to resolve accessibility issues if you’re downloading a model in China. We do not |
| guarantee the timeliness or safety of the source, and you should refer to the mirror site for more |
| information. |
| device_map (`str` or `Dict[str, Union[int, str, torch.device]]`, *optional*): |
| A map that specifies where each submodule should go. It doesn’t need to be defined for each |
| parameter/buffer name; once a given module name is inside, every submodule of it will be sent to the |
| same device. |
| |
| Set `device_map="auto"` to have 🤗 Accelerate automatically compute the most optimized `device_map`. For |
| more information about each option see [designing a device |
| map](https://hf.co/docs/accelerate/main/en/usage_guides/big_modeling#designing-a-device-map). |
| max_memory (`Dict`, *optional*): |
| A dictionary device identifier for the maximum memory. Will default to the maximum memory available for |
| each GPU and the available CPU RAM if unset. |
| offload_folder (`str` or `os.PathLike`, *optional*): |
| The path to offload weights if device_map contains the value `"disk"`. |
| offload_state_dict (`bool`, *optional*): |
| If `True`, temporarily offloads the CPU state dict to the hard drive to avoid running out of CPU RAM if |
| the weight of the CPU state dict + the biggest shard of the checkpoint does not fit. Defaults to `True` |
| when there is some disk offload. |
| low_cpu_mem_usage (`bool`, *optional*, defaults to `True` if torch version >= 1.9.0 else `False`): |
| Speed up model loading only loading the pretrained weights and not initializing the weights. This also |
| tries to not use more than 1x model size in CPU memory (including peak memory) while loading the model. |
| Only supported for PyTorch >= 1.9.0. If you are using an older version of PyTorch, setting this |
| argument to `True` will raise an error. |
| use_safetensors (`bool`, *optional*, defaults to `None`): |
| If set to `None`, the safetensors weights are downloaded if they're available **and** if the |
| safetensors library is installed. If set to `True`, the model is forcibly loaded from safetensors |
| weights. If set to `False`, safetensors weights are not loaded. |
| kwargs (remaining dictionary of keyword arguments, *optional*): |
| Can be used to overwrite load and saveable variables (the pipeline components of the specific pipeline |
| class). The overwritten components are passed directly to the pipelines `__init__` method. See example |
| below for more information. |
| variant (`str`, *optional*): |
| Load weights from a specified variant filename such as `"fp16"` or `"ema"`. This is ignored when |
| loading `from_flax`. |

| Instantiates a inpainting Pytorch diffusion pipeline from pretrained pipeline weight. |
| |
| The from_pretrained() method takes care of returning the correct pipeline class instance by: |
| 1. Detect the pipeline class of the pretrained_model_or_path based on the _class_name property of its |
| config object |
| 2. Find the inpainting pipeline linked to the pipeline class using pattern matching on pipeline class name. |
| |
| If a `controlnet` argument is passed, it will instantiate a [`StableDiffusionControlNetInpaintPipeline`] |
| object. |
| |
| The pipeline is set in evaluation mode (`model.eval()`) by default. |
| |
| If you get the error message below, you need to finetune the weights for your downstream task: |
| |
| ``` |
| 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: |
| - 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 |
| You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference. |
| ``` |
| |
| Parameters: |
| pretrained_model_name_or_path (`str` or `os.PathLike`, *optional*): |
| Can be either: |
| |
| - A string, the *repo id* (for example `CompVis/ldm-text2im-large-256`) of a pretrained pipeline |
| hosted on the Hub. |
| - A path to a *directory* (for example `./my_pipeline_directory/`) containing pipeline weights |
| saved using |
| [`~DiffusionPipeline.save_pretrained`]. |
| torch_dtype (`str` or `torch.dtype`, *optional*): |
| Override the default `torch.dtype` and load the model with another dtype. If "auto" is passed, the |
| dtype is automatically derived from the model's weights. |
| force_download (`bool`, *optional*, defaults to `False`): |
| Whether or not to force the (re-)download of the model weights and configuration files, overriding the |
| cached versions if they exist. |
| cache_dir (`Union[str, os.PathLike]`, *optional*): |
| Path to a directory where a downloaded pretrained model configuration is cached if the standard cache |
| is not used. |
| resume_download (`bool`, *optional*, defaults to `False`): |
| Whether or not to resume downloading the model weights and configuration files. If set to `False`, any |
| incompletely downloaded files are deleted. |
| proxies (`Dict[str, str]`, *optional*): |
| A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128', |
| 'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request. |
| output_loading_info(`bool`, *optional*, defaults to `False`): |
| Whether or not to also return a dictionary containing missing keys, unexpected keys and error messages. |
| local_files_only (`bool`, *optional*, defaults to `False`): |
| 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. |
| use_auth_token (`str` or *bool*, *optional*): |
| The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from |
| `diffusers-cli login` (stored in `~/.huggingface`) is used. |
| revision (`str`, *optional*, defaults to `"main"`): |
| The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier |
| allowed by Git. |
| custom_revision (`str`, *optional*, defaults to `"main"`): |
| The specific model version to use. It can be a branch name, a tag name, or a commit id similar to |
| `revision` when loading a custom pipeline from the Hub. It can be a 🤗 Diffusers version when loading a |
| custom pipeline from GitHub, otherwise it defaults to `"main"` when loading from the Hub. |
| mirror (`str`, *optional*): |
| Mirror source to resolve accessibility issues if you’re downloading a model in China. We do not |
| guarantee the timeliness or safety of the source, and you should refer to the mirror site for more |
| information. |
| device_map (`str` or `Dict[str, Union[int, str, torch.device]]`, *optional*): |
| A map that specifies where each submodule should go. It doesn’t need to be defined for each |
| parameter/buffer name; once a given module name is inside, every submodule of it will be sent to the |
| same device. |
| |
| Set `device_map="auto"` to have 🤗 Accelerate automatically compute the most optimized `device_map`. For |
| more information about each option see [designing a device |
| map](https://hf.co/docs/accelerate/main/en/usage_guides/big_modeling#designing-a-device-map). |
| max_memory (`Dict`, *optional*): |
| A dictionary device identifier for the maximum memory. Will default to the maximum memory available for |
| each GPU and the available CPU RAM if unset. |
| offload_folder (`str` or `os.PathLike`, *optional*): |
| The path to offload weights if device_map contains the value `"disk"`. |
| offload_state_dict (`bool`, *optional*): |
| If `True`, temporarily offloads the CPU state dict to the hard drive to avoid running out of CPU RAM if |
| the weight of the CPU state dict + the biggest shard of the checkpoint does not fit. Defaults to `True` |
| when there is some disk offload. |
| low_cpu_mem_usage (`bool`, *optional*, defaults to `True` if torch version >= 1.9.0 else `False`): |
| Speed up model loading only loading the pretrained weights and not initializing the weights. This also |
| tries to not use more than 1x model size in CPU memory (including peak memory) while loading the model. |
| Only supported for PyTorch >= 1.9.0. If you are using an older version of PyTorch, setting this |
| argument to `True` will raise an error. |
| use_safetensors (`bool`, *optional*, defaults to `None`): |
| If set to `None`, the safetensors weights are downloaded if they're available **and** if the |
| safetensors library is installed. If set to `True`, the model is forcibly loaded from safetensors |
| weights. If set to `False`, safetensors weights are not loaded. |
| kwargs (remaining dictionary of keyword arguments, *optional*): |
