Solution:
You need to update the file causing the issue, for that open cmd and type: pip show basicsr
Note down the location & search for the degradations.py file.
Open it & edit the following line:
from torchvision.transforms.functional_tensor import rgb_to_grayscale
to
from torchvision.transforms.functional import rgb_to_grayscale

This worked perfectly for me.
