| Note: | |
| For your custom dataset, there is no need to hard-code metadata anywhere in the code. | |
| For example, for COCO-format dataset, metadata will be obtained automatically | |
| when calling `load_coco_json`. For other dataset, metadata may also be obtained in other ways | |
| during loading. | |
| However, we hard-coded metadata for a few common dataset here. | |
| The only goal is to allow users who don't have these dataset to use pre-trained models. | |
| Users don't have to download a COCO json (which contains metadata), in order to visualize a | |
| COCO model (with correct class names and colors). | |
