PyTorch 安装问题- 使用 Jupyter notebook 和 Conda navigator 找不到包

Question

我尝试使用 PyTorch 官方网站上的安装代码来安装 PyTorch。我运行在 Conda 导航器上的 Jupyter notebook 本地

conda install pytorch torchvision cudatoolkit=10.2 -c pytorch

我收到以下错误

    PackagesNotFoundError: The following packages are not available from current channels:

  - pytorch
  - cudatoolkit=10.2

Current channels:

  - https://conda.anaconda.org/pytorch/win-32
  - https://conda.anaconda.org/pytorch/noarch
  - https://repo.anaconda.com/pkgs/main/win-32
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-32
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-32
  - https://repo.anaconda.com/pkgs/msys2/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.

怎么办？

Answer 1

TL;DR 使用 64 位 Anaconda

conda 管理一个平台和架构的包。

您似乎安装了 32 位 (x86) Win Anaconda 版本，此处：

- https://conda.anaconda.org/pytorch/win-32

你可以在link下查看那个频道（https://conda.anaconda.org/pytorch/win-32) does not contain any pytorch package, and same is for this one: https://conda.anaconda.org/pytorch/noarch

如果您查看 win64：https://conda.anaconda.org/pytorch/win-64 它实际上包含 pytorch 个包。

因此，pytorch 频道中没有 pytorch x86 软件包，而且无法创建其他架构的环境，这意味着您需要安装 64-位 Anaconda 以使用 pytorch.
