Cloning environment with selected packages in conda

Question

I would like to know if it is possible to clone an environment with the selected packages only.

Doing conda create -n name --clone base will clone the base environment including all the packages which sometimes unnecessary for a certain project.

Uninstalling the packages on the new environment could be a solution but I'm trying to find a way that is more effective and explicit.

Answer 1

Expanding on what @darthbith said. Cloning creates an exact copy of every package in the environment. If you want to clone only a portion of the environment, you can create a spec file using:

conda list -n base --export > environment.yaml

This will dump a list of every package in the base environment as a yaml file. You can edit the file to keep only the packages you want and conda will figure out the rest.

Answer 2

此命令生成另一个 conda 环境test1 ，其中包含来自基础软件包的请求包numpy scipy pandas ，而无需下载任何内容：

conda create -n test1 --offline numpy scipy pandas
