ERROR: Could not find a version that satisfies the requirement torch＞=1.6.0 (from -r requirements.tx

使用pip安装PyTorch时报如下错误：

ERROR: Could not find a version that satisfies the requirement torch>=1.6.0 (from -r requirements.txt (line 11)) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)

ERROR: No matching distribution found for torch>=1.6.0 (from -r requirements.txt (line 11))

 

pip安装Pytorch时使用国内镜像源，会报如上错误。解决方案如下：

参考：https://blog.youkuaiyun.com/Jwenxue/article/details/107520422中给出的网址，选择合适的版本，根据给出的命令：

比如：pip install torch==1.6.0+cu101 torchvision==0.7.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

到网址：https://download.pytorch.org/whl/torch_stable.html选择合适的版本，使用迅雷下载，完成后再使用pip安装即可。

进入下载的whl文件目录，运行如下命令：

pip install "torch-1.6.0+cu101-cp38-cp38-win_amd64.whl" "torchvision-0.7.0+cu101-cp38-cp38-win_amd64.whl"
