Google Colab Unespected Error

[toux92]

just opened the colab version after some months and I got this when start inference:

Traceback (most recent call last):

from torchvision.transforms.functional_tensor import rgb_to_grayscale
ModuleNotFoundError: No module named 'torchvision.transforms.functional_tensor'

I also found this on Update degradations.py #624 :

"Fix #533 functional_tensor not found

The torchvision.transforms.functional_tensor module is deprecated since torchvision 0.15, and it will be no longer available in 0.17

Change import source of rgb_to_grayscale from torchvision.transforms.functional_tensor to torchvision.transforms.functional, so as to avoid the deprecation warning."

Since I'm using Real Esrgan on Colab I can't find "degradation.py" so I don't know how to solve this problem (assuming that this will solve the problem).

I released a fixed version to address this issue. Use pip install basicsr-fixed instead of pip install basicsr.
