如何为pyculibforwindows添加正确的分销渠道？

Question

我试图通过conda包发行版安装Nvidia的GPU python包，但遇到以下错误：

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

什么是正确的分销渠道丘比和pyculib包？在

Answer 1

Numba通道

另一个选择是从numba渠道（他们毕竟是维护组织）：

conda install -n my_env -c numba pyculib

这样做的一点好处是Numba将pyculib维护为NumPy 1.15，而anaconda频道上的版本最多只能运行nump1.13。在

至于CuPy，它可以直接在Python频道上获得，而且由于它是主动维护的（与pyculib）不同，您不需要免费频道来访问它。在

Answer 2

pyculib被收集在free通道中。但是free通道在conda4.7中被删除。在

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free通道。在

1. 全局启用free通道全局。在

   conda config  set restore_free_channel true
   conda install pyculib
   

2. 仅对当前活动环境启用free通道。在

3. 临时在单个命令中使用free通道。在

   CONDA_RESTORE_FREE_CHANNEL=1 conda install pyculib
