One of the experience of solving problems with code error reporting: CUDA does not match pytorch

ask       topic ：D:\python\envs\yolov5\lib\site-packages\torch\autocast_mode.py:141: UserWarning: User provided device_type of 'cuda', but CUDA is not available. Disabling

  warnings.warn('User provided device_type of \'cuda\', but CUDA is not available. Disabling')

primary       because ：cuda And pytorch Mismatch

import torch

print(torch.__version__)

print(torch.cuda.is_available())

resolvent ： Change autocast_mode.py Comment output statement in
