Subject: [PATCH] Fix import error for rgb_to_grayscale

The import statement for rgb_to_grayscale was referencing the
torchvision.transforms.functional_tensor module, which is not available in
the current version of torchvision. Updated the import statement to use
torchvision.transforms.functional instead, resolving the ModuleNotFoundError.

This commit fixes the issue where the script was failing to run due to the
missing module. The change ensures compatibility with the installed version
of torchvision and allows the script to execute successfully.
