No module named 'basicsr'

I have got the same problem.
Here is my solusion.

First download the 'basicsr' package on your own conda environment and try to import it,
you wil find some error like this

>>> from basicsr.utils.download_util import load_file_from_url
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\__init__.py", line 4, in <module>
    from .data import *
  File "D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\data\__init__.py", line 22, in <module>
    _dataset_modules = [importlib.import_module(f'basicsr.data.{file_name}') for file_name in dataset_filenames]
  File "D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\data\__init__.py", line 22, in <listcomp>
    _dataset_modules = [importlib.import_module(f'basicsr.data.{file_name}') for file_name in dataset_filenames]
  File "D:\miniconda3\envs\stable-web\lib\importlib\__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\data\realesrgan_dataset.py", line 11, in <module>
    from basicsr.data.degradations import circular_lowpass_kernel, random_mixed_kernels
  File "D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\data\degradations.py", line 8, in <module>
    from torchvision.transforms.functional_tensor import rgb_to_grayscale
ModuleNotFoundError: No module named 'torchvision.transforms.functional_tensor'

Find the D:\miniconda3\envs\stable-web\lib\site-packages\basicsr\data\degradations.py under you conda env,
modify the from torchvision.transforms.functional_tensor import rgb_to_grayscale to
from torchvision.transforms.functional import rgb_to_grayscale

Later copy the "basicsr" and "basicsr-1.4.2.dist-info" folder
under "D:\miniconda3\envs\stable-web\lib\site-packages\" to your web-ui env site-packages
"stable-diffusion-webui\venv\Lib\site-packages".

Hope it can help.
