to fix functional_tensor not found error, I release a new version of basicsr

[14790897]

I released a fixed version to address this issue.

Install basicsr-fixed with pip install basicsr-fixed after all other packages have been installed to overwrite the basicsr package that may have been installed by other packages.

i did fix it by modify the actual file degradations.py, i do have to do it manually everytime i use it (colab), its not the best way but it works
