问题描述
我正在尝试在conda env下安装特定的PyTorch版本：
使用点子：
pip3 install pytorch==1.0.1
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement pytorch==1.0.1 (from versions: 0.1.2,1.0.2)
ERROR: No matching distribution found for pytorch==1.0.1
使用Conda：
conda install pytorch==1.0.1

我可以在https://anaconda.org/soumith/pytorch下找到该版本，但是有没有办法从控制台找到并安装？
解决方法
您可以从官方Pytorch's Conda package下载/安装所需的版本。您指定的链接是旧版本，现在不支持/更新退出！！
像这样安装所需的版本：
conda install pytorch==1.0.1 torchvision==0.2.2 -c pytorch
如果您要查找pip版本，也可以从here查看和访问所有版本。
只需执行：
pip install torch===1.0.1 -f https://download.pytorch.org/whl/torch_stable.html
您也可以随时在此处检查previous versions。
,您可以使用以下任一方法下载先前版本的 pytorch： 针对 Linux/Windows 特定操作系统
# CUDA 9.0
conda install pytorch==1.0.1 torchvision==0.2.2 cudatoolkit=9.0 -c pytorch
# CUDA 10.0
conda install pytorch==1.0.1 torchvision==0.2.2 cudatoolkit=10.0 -c pytorch
# CPU Only
conda install pytorch-cpu==1.0.1 torchvision-cpu==0.2.2 cpuonly -c pytorch
