在conda-forge中找不到较早版本的Python

Question

我正试图使用conda install -c conda-forge python=3.6.15在Conda虚拟环境中安装Python3.6.15，但始终得到以下错误：

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

  - python=3.6.15

Current channels:

  - https://conda.anaconda.org/conda-forge/osx-arm64
  - https://conda.anaconda.org/conda-forge/noarch
  - https://repo.anaconda.com/pkgs/main/osx-arm64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/osx-arm64
  - https://repo.anaconda.com/pkgs/r/noarch

我试过在我的频道上贴上conda-forge，但没有用。另外，使用conda create -n OldTest python=3.6.15 anaconda创建一个新的虚拟环境也会产生同样的错误。如何使用Conda安装我想要的Python版本？

Answer 1

您需要有一个非本地运行的环境(即x64通过rosetta)：

conda create -n oldTF
conda activate oldTF
conda config --env --set subdir osx-64
conda install python tensorflow=x.x #Only put the specific packages that you need here. Probably no reason to inlcude all of anaconda
