python - 如何为 Windows 的 pyculib 添加正确的分发 channel ？

Question

我正在尝试通过 conda 包分发安装 Nvidia 的 GPU python 包，但我遇到了以下错误:

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

  - pyculib

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-64
  - https://repo.anaconda.com/pkgs/msys2/noarch

CuPy 和 pyculib 包的正确分发 channel 是什么？

Answer 1

pyculib 收集在免费 channel 。但是 free channel 在 conda 4.7 中被移除了。

Quote from Why We Removed the “Free” Channel in Conda 4.7

One of the changes we made in Conda 4.7 was the removal of a software collection called “free” from the default channel configuration. The “free” channel is our collection of packages prior to the switch in recipes/compilers that we did for the Anaconda Distribution 5.0 release.

解决方案:重新启用免费 channel 。

1. 全局启用免费 channel 。

   conda config --set restore_free_channel true
   conda install pyculib
   

2. 仅为当前事件环境启用免费 channel 。

   conda config --set restore_free_channel true --env
   conda install pyculib
   

3. 临时在单个命令中使用免费 channel 。

   CONDA_RESTORE_FREE_CHANNEL=1 conda install pyculib
