Question

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
    Collecting package metadata (current_repodata.json): done
    Solving environment: failed with initial frozen solve. Retrying with flexible solve.

    PackagesNotFoundError: The following packages are not available from current channels:
    
      - pytorch==1.0.1
    
    Current channels:

      - https://repo.anaconda.com/pkgs/r/osx-64
      - https://repo.anaconda.com/pkgs/r/noarch
    
    To search for alternate channels that may provide the conda package you're
    looking for, navigate to
    
        https://anaconda.org
    
    and use the search bar at the top of the page.

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？

Answer 1

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。

Answer 2

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
