+        Instantiate a PyTorch diffusion pipeline from pre-trained pipeline weights saved in the original .ckpt format.
+
+        The pipeline is set in evaluation mode by default using `model.eval()` (Dropout modules are deactivated).
+
+        Parameters:
+            pretrained_model_link_or_path (`str` or `os.PathLike`, *optional*):
+                Can be either:
+                    - A link to the .ckpt file on the Hub. Should be in the format
+                      `"https://huggingface.co/<repo_id>/blob/main/<path_to_file>"`
+                    - A path to a *file* containing all pipeline weights.
+            torch_dtype (`str` or `torch.dtype`, *optional*):
+                Override the default `torch.dtype` and load the model under this dtype. If `"auto"` is passed the dtype
+                will be 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 in which a downloaded pretrained model configuration should be cached if the
+                standard cache should not be used.
+            resume_download (`bool`, *optional*, defaults to `False`):
+                Whether or not to delete incompletely received files. Will attempt to resume the download if such a
+                file exists.
+            proxies (`Dict[str, str]`, *optional*):
+                A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128',
+                'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
+            local_files_only (`bool`, *optional*, defaults to `False`):
+                Whether or not to only look at local files (i.e., do not try to download the model).
+            use_auth_token (`str` or *bool*, *optional*):
+                The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated
+                when running `huggingface-cli login` (stored in `~/.huggingface`).
+            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, since we use a
+                git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any
+                identifier allowed by git.
+            use_safetensors (`bool`, *optional* ):
+                If set to `True`, the pipeline will be loaded from `safetensors` weights. If set to `None` (the
+                default). The pipeline will load using `safetensors` if the safetensors weights are available *and* if
+                `safetensors` is installed. If the to `False` the pipeline will *not* use `safetensors`.
+            extract_ema (`bool`, *optional*, defaults to `False`): Only relevant for
+                checkpoints that have both EMA and non-EMA weights. Whether to extract the EMA weights or not. Defaults
+                to `False`. Pass `True` to extract the EMA weights. EMA weights usually yield higher quality images for
+                inference. Non-EMA weights are usually better to continue fine-tuning.
+            upcast_attention (`bool`, *optional*, defaults to `None`):
+                Whether the attention computation should always be upcasted. This is necessary when running stable
+            image_size (`int`, *optional*, defaults to 512):
+                The image size that the model was trained on. Use 512 for Stable Diffusion v1.X and Stable Diffusion v2
+                Base. Use 768 for Stable Diffusion v2.
+            prediction_type (`str`, *optional*):
+                The prediction type that the model was trained on. Use `'epsilon'` for Stable Diffusion v1.X and Stable
+                Diffusion v2 Base. Use `'v_prediction'` for Stable Diffusion v2.
+            num_in_channels (`int`, *optional*, defaults to None):
+                The number of input channels. If `None`, it will be automatically inferred.
+            scheduler_type (`str`, *optional*, defaults to 'pndm'):
+                Type of scheduler to use. Should be one of `["pndm", "lms", "heun", "euler", "euler-ancestral", "dpm",
+                "ddim"]`.
+            load_safety_checker (`bool`, *optional*, defaults to `True`):
+                Whether to load the safety checker or not. Defaults to `True`.
+            kwargs (remaining dictionary of keyword arguments, *optional*):
+                Can be used to overwrite load - and saveable variables - *i.e.* the pipeline components - of the
+                specific pipeline class. The overwritten components are then directly passed to the pipelines
+                `__init__` method. See example below for more information.

     Pipeline for pixel-level image editing by following text instructions. Based on Stable Diffusion.
 
     This model inherits from [`DiffusionPipeline`]. Check the superclass documentation for the generic methods the
     library implements for all the pipelines (such as downloading or saving, running on a particular device, etc.)
 
+    In addition the pipeline inherits the following loading methods:
