Instructions To Reproduce the Issue:

Please include the following (depending on what the issue is):

1. Any changes you made (git diff) or code you wrote

# Device on which to run the model
# Set to cuda to load on GPU
device = "cuda" if torch.cuda.is_available() else "cpu"

# Pick a pretrained model and load the pretrained weights
model_name = "slowfast_r50"
model = torch.hub.load("facebookresearch/pytorchvideo", model=model_name, pretrained=True)
# Set to eval mode and move to desired device
model = model.to(device)
model = model.eval()```
2. The exact command(s) you ran:
3. What you observed (including the full logs):

ImportError: cannot import name 'c2d_r50' from 'pytorchvideo.models.hub' (/home/shengguang/PycharmProjects/EurekAI-LM/venv/lib/python3.12/site-packages/pytorchvideo/models/hub/init.py)```

Please also simplify the steps as much as possible so they do not require additional resources to
run, such as a private dataset, models, etc.
