torchvision.transforms¶. Transforms are common image transformations. They can be chained together using Compose.Most transform classes have a function equivalent: functional transforms give fine-grained control over the transformations. This is useful if you have to build a more complex transformation pipeline (e.g. in the case of segmentation tasks).
