🐛 Bugs / Unexpected behaviors

when using

model_name = "slowfast_r50"
SLOWFAST50_MODEL = torch.hub.load("facebookresearch/pytorchvideo", model=model_name, pretrained=True)

I came across bug follows

/root/.cache/torch/hub/facebookresearch_pytorchvideo_master/hubconf.py in <module>()
      2 
      3 dependencies = ["torch"]
----> 4 from pytorchvideo.models.hub import (  # noqa: F401, E402
      5     efficient_x3d_s,
      6     efficient_x3d_xs,
ImportError: cannot import name 'slow_r50_detection' from 'pytorchvideo.models.hub' (/usr/local/lib/python3.7/dist-packages/pytorchvideo/models/hub/__init__.py)

Instructions To Reproduce the Issue:

1. My code came from https://pytorchvideo.org/docs/tutorial_torchhub_inference.

2. My environment is google colab.

It Seems is a bug from official respository. Thanks

Second it, just met the same problem! (For now I just comment out the models that raise error :/ )

@TianhaoFu , @Meryl-Fang , could please provide more details on how you installed pytorchvideo and your testing environment?

When I ran the following notebook in Colab, I did not have issues - https://colab.research.google.com/github/facebookresearch/pytorchvideo/blob/master/tutorials/torchhub_inference_tutorial.ipynb

Same.
I just copy code from https://pytorchvideo.org/docs/tutorial_torchhub_inference cell by cell to google coolab and got this error on model import from torch.hub
Install lib in first cell !pip install pytorchvideo

[kalyanvasudev]

Got it, I was able to pinpoint it down. Looks like the pip build is out of date. I will update it today.

Alternatively, reinstalling Pytorchvideo using !pip install "git+https://github.com/facebookresearch/pytorchvideo.git" should fix the problem.

Even though I reinstalled Pytorchvideo using pip install "git+https://github.com/facebookresearch/pytorchvideo.git" I am still encountering the same problem. My environment is a Jupytr notebook.

The error still persists on my local machine even if i install pytorchvideo from git. There is no problem on google colab though.

Hi, I've updated the pip builds too to match the latest commits. All the installation methods mentioned here should work now. I just verified it.

Please let me know if the issue persists!

[kalyanvasudev]

Closing the issue since it has been resolved. But feel free to open it again if the problem still persists for you.

For all of you who installed version 0.1.1, I'd recommend uninstalling it and installing 0.1.2 or higher. Thanks!
