在这个链接中找你需要下的torch版本，会自动帮你匹配好torchvision、torchaudio版本，生成一个pip命令如下：
https://pytorch.org/get-started/previous-versions/

(base) E:\Python\workspace>pip install torch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0

在终端Terminal 中输入以上结果后，就自动帮你安装了。如下：

(base) E:\Python\workspace>pip install torch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0
