CocoDetection

class torchvision.datasets.CocoDetection(root: str, annFile: str, transform: Optional[Callable] = None, target_transform: Optional[Callable] = None, transforms: Optional[Callable] = None)[source]

MS Coco Detection Dataset.

It requires the COCO API to be installed.

Parameters:
  • root (string) – Root directory where images are downloaded to.

  • annFile (string) – Path to json annotation file.

  • transform (callable, optional) – A function/transform that takes in an PIL image and returns a transformed version. E.g, transforms.PILToTensor

  • target_transform (callable, optional) – A function/transform that takes in the target and transforms it.

  • transforms (callable, optional) – A function/transform that takes input sample and its target as entry and returns a transformed version.
