pip 安装 pytorch环境_torch==2.0.1

直接 pip install torch -i https://pypi.tuna.tsinghua.edu.cn/simple

失败

pip install --upgrade torch torchvision -i https://pypi.tuna.tsinghua.edu.cn/simple

还是失败

ERROR: torchvision 0.5.0 has requirement torch==1.4.0, but you'll have torch 0.1.2.post2 which is incompatible.

再次尝试

pip install --upgrade torch==1.4.0 torchvision==0.5.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
但是还是安装失败
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
ERROR: Could not find a version that satisfies the requirement torch==1.4.0 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)

最后找到一种新的方式：
https://pytorch.org/get-started/locally/

最后安装成功（还得看网速，在另一台笔记本上面就是超时了），注意是使用 pip install，而不是 conda install(安装失败)

pip install torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
