After installing all packages, on running the demo video script by using `python scripts/demo_video.py --video-name examples/dance.mp4 --out-dir res_dance --save-pk --save-im```, I get the above error. The full error message is enclosed below.

  warnings.warn(
/home/cvit/miniconda3/envs/hybrik/lib/python3.9/site-packages/torchvision/models/_utils.py:223: UserWarning: Arguments other than a weight enum or `None` for 'weights' are deprecated since 0.13 and may be removed in the future. The current behavior is equivalent to passing `weights=FasterRCNN_ResNet50_FPN_Weights.COCO_V1`. You can also use `weights=FasterRCNN_ResNet50_FPN_Weights.DEFAULT` to get the most up-to-date weights.

I was able to solve the above issue by renaming hybrik_hrnet48_w3dpw.pth to hybrik_hrnet.pth. And my code works now. @Jeff-sjtu : please confirm if this is a correct method to solve the above issue and won't cause some other unexpected behaviour (my code is working now)
