代码报错解决问题经验之一：cuda与pytorch不匹配

问     题：D:pythonenvsyolov5libsite-packagestorchautocast_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')

原     因：cuda与pytorch不匹配

import torch

print(torch.__version__)

print(torch.cuda.is_available())

解决方法：改autocast_mode.py中注释输出语句
