+    Loads a (potentially sharded) checkpoint inside a model, potentially sending weights to a given device as they are

+
+    Args:
+        model (`torch.nn.Module`): The model in which we want to load a checkpoint.
+        checkpoint (`str` or `os.PathLike`):
+            The folder checkpoint to load. It can be:
+            - a path to a file containing a whole model state dict
+            - a path to a `.json` file containing the index to a sharded checkpoint
+            - a path to a folder containing a unique `.index.json` file and the shards of a checkpoint.
+        device_map (`Dict[str, Union[int, str, torch.device]]`, *optional*):
+            A map that specifies where each submodule should go. It doesn't need to be refined to each parameter/buffer
+            name, once a given module name is inside, every submodule of it will be sent to the same device.
+
+            To have Accelerate compute the most optimized `device_map` automatically, set `device_map="auto"`. For more
+            information about each option see [here](../concept_guides/big_model_inference#designing-a-device-map).
+            Defaults to None, which means [`dispatch_model`] will not be called.
+        max_memory (`Dict`, *optional*):
+            A dictionary device identifier to maximum memory. Will default to the maximum memory available for each GPU
+            and the available CPU RAM if unset.
+        no_split_module_classes (`List[str]`, *optional*):
+            A list of layer class names that should never be split across device (for instance any layer that has a
+            residual connection).
+        offload_folder (`str` or `os.PathLike`, *optional*):
+            If the `device_map` contains any value `"disk"`, the folder where we will offload weights.
+        offload_buffers (`bool`, *optional*, defaults to `False`):
+            In the layers that are offloaded on the CPU or the hard drive, whether or not to offload the buffers as
+            well as the parameters.
+        dtype (`str` or `torch.dtype`, *optional*):
+            If provided, the weights will be converted to that type when loaded.
+        offload_state_dict (`bool`, *optional*):
+            If `True`, will temporarily offload the CPU state dict on the hard drive to avoid getting out of CPU RAM if
+            the weight of the CPU state dict + the biggest shard does not fit. Will default to `True` if the device map
+            picked contains `"disk"` values.
+        skip_keys (`str` or `List[str]`, *optional*):
+            A list of keys to ignore when moving inputs or outputs between devices.
+        preload_module_classes (`List[str]`, *optional*):
+            A list of classes whose instances should load all their weights (even in the submodules) at the beginning
+            of the forward. This should only be used for classes that have submodules which are registered but not
+            called directly during the forward, for instance if a `dense` linear layer is registered, but at forward,
+            `dense.weight` and `dense.bias` are used in some operations instead of calling `dense` directly.
+        force_hooks (`bool`, *optional*, defaults to `False`):
+            Whether or not to force device hooks to be attached to the model even if all layers are dispatched to a
+            single device.
+        strict (`bool`, *optional*, defaults to `False`):
+            Whether to strictly enforce that the keys in the checkpoint state_dict match the keys of the model's
+            state_dict.
