  • My post explains CocoCaptions() using train2017 with captions_train2017.json, instances_train2017.json and person_keypoints_train2017.json, val2017 with captions_val2017.json, instances_val2017.json and person_keypoints_val2017.json and test2017 with image_info_test2017.json and image_info_test-dev2017.json.
  • My post explains CocoCaptions() using train2017 with stuff_train2017.json, val2017 with stuff_val2017.json, stuff_train2017_pixelmaps with stuff_train2017.json, stuff_val2017_pixelmaps with stuff_val2017.json, panoptic_train2017 with panoptic_train2017.json, panoptic_val2017 with panoptic_val2017.json and unlabeled2017 with image_info_unlabeled2017.json.
  • My post explains CocoDetection() using train2014 with captions_train2014.json, instances_train2014.json and person_keypoints_train2014.json, val2014 with captions_val2014.json, instances_val2014.json and person_keypoints_val2014.json and test2017 with image_info_test2014.json, image_info_test2015.json and image_info_test-dev2015.json.

  • My post explains MS COCO.

CocoCaptions() can use MS COCO dataset as shown below. *This is for train2014 with captions_train2014.json, instances_train2014.json and person_keypoints_train2014.json, val2014 with captions_val2014.json, instances_val2014.json and person_keypoints_val2014.json and test2017 with image_info_test2014.json, image_info_test2015.json and image_info_test-dev2015.json:

*Memos:

  • The 1st argument is root(Required-Type:str or pathlib.Path): *Memos:
    • It’s the path to the images.
    • An absolute or relative path is possible.
  • The 2nd argument is annFile(Required-Type:str or pathlib.Path): *Memos:
    • It’s the path to the annotations.
    • An absolute or relative path is possible.
  • The 3rd argument is transform(Optional-Default:None-Type:callable).
  • The 4th argument is target_transform(Optional-Default:None-Type:callable).
  • The 5th argument is transforms(Optional-Default:None-Type:callable).
  • It must need pycocotools on Windows, Linux and macOS: *Memos:
    • e.g. pip install pycocotools.
    • e.g. conda install conda-forge::pycocotools.
    • Don’t use the ways to install pycocotools from cocodataset/cocoapi and philferriere/cocoapi because they don’t work and even if they are possible, they take a long time to install pycocotools.
  • You need to manually download and extract the datasets(images and annotations) which you want to coco/ from here as shown below. *You can use other folder structure:
