class torchvision.transforms.v2.Compose(transforms: Sequence[Callable])[source]

[BETA] Composes several transforms together.


The Compose transform is in Beta stage, and while we do not expect major breaking changes, some APIs may still change according to user feedback. Please submit any feedback you may have in this issue:, and you can also check out to learn more about the APIs that we suspect might involve future changes.

This transform does not support torchscript. Please, see the note below.


transforms (list of Transform objects) – list of transforms to compose.


>>> transforms.Compose([
>>>     transforms.CenterCrop(10),
>>>     transforms.PILToTensor(),
>>>     transforms.ConvertImageDtype(torch.float),
>>> ])


In order to script the transformations, please use torch.nn.Sequential as below.

>>> transforms = torch.nn.Sequential(
>>>     transforms.CenterCrop(10),
>>>     transforms.Normalize((0.485, 0.456, 0.406), (0.229, 0.224, 0.225)),
>>> )
>>> scripted_transforms = torch.jit.script(transforms)

Make sure to use only scriptable transformations, i.e. that work with torch.Tensor, does not require lambda functions or PIL.Image.

extra_repr() str[source]

Set the extra representation of the module

To print customized extra information, you should re-implement this method in your own modules. Both single-line and multi-line strings are acceptable.

forward(*inputs: Any) Any[source]

Defines the computation performed at every call.

Should be overridden by all subclasses.


Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
