pytorch gpu~ cuda cudacnn安装是否成功的测试代码

# CUDA TEST
import torch
x = torch.Tensor([1.0])
xx = x.cuda()
print(xx)

# CUDNN TEST
from torch.backends import cudnn
print(cudnn.is_acceptable(xx))

#注意！安装目录要英文目录不要搞在中文目录 ！不然可能报些奇奇怪怪的bug!

 windows上报错：Could not find a version that satisfies the requirement torch==0.4.1->安装pytorch0.4.1 :https://blog.csdn.net/weixin_41010198/article/details/103107083
