This error is generated trying to run colab demo (step 3)
https://colab.research.google.com/drive/1k2Zod6kSHEvraybHl50Lys0LerhyTMCo?usp=sharing

and any other code attempts give the same error
Any ideas how to fix it?

edit file "degradation.py" line 8 from:
from torchvision.transforms.functional_tensor import rgb_to_grayscale
to:
from torchvision.transforms._functional_tensor import rgb_to_grayscale

for anyone found it difficult to find the file,

# Path to the file
file_path = '/usr/local/lib/python3.10/dist-packages/basicsr/data/degradations.py'

# Open the file, read its contents, and replace the desired line
with open(file_path, 'r') as file:
    code = file.read()

# Replace the import line
modified_code = code.replace(
    "from torchvision.transforms.functional_tensor import rgb_to_grayscale",
    "from torchvision.transforms._functional_tensor import rgb_to_grayscale"
)

# Write the modified code back to the file
with open(file_path, 'w') as file:
    file.write(modified_code)

or downgrade your torchvision to =0.14.1
