I'm guessing for the time being you may need to check and downgrade your torchvision version.

I've been noticing this deprecation warning with torchvision 0.16.2+cu118 but it is still working and processing properly:

UserWarning: The torchvision.transforms.functional_tensor module is deprecated in 0.15 and will be **removed in 0.17**. Please don't rely on it. You probably just need to use APIs in torchvision.transforms.functional or in torchvision.transforms.v2.functional.

I have forked the basicsr repo and updated the import to make it work, to use it you have to:

1. Install it pip install new-basicsr

2. Change the requirements.txt from:
   basicsr>=1.4.2 to new-basicsr

3. Uninstall the old basicsr pip uninstall basicsr

4. Reinstall requirements.txt

Hope that helps :)

not solve this problem

Just tried it on 3 environments and OS and it does work on a fresh environment with my torchvision fix....
The error literally points to torchvision...

Change in degradations.py file..
from

from torchvision.transforms.functional_tensor import rgb_to_grayscale

to

from torchvision.transforms.functional import rgb_to_grayscale

Now that will be wrks fine 👍
