您如何“克隆"到您的计算机?将conda环境转换为根环境? [英] How can you "clone" a conda environment into the root environment?

问题描述

我希望conda的根环境在另一个环境中复制所有软件包.如何才能做到这一点?

I'd like the root environment of conda to copy all of the packages in another environment. How can this be done?

推荐答案

有一些选项可以将依赖项名称/URL/版本复制到文件中.

There are options to copy dependency names/urls/versions to files.

通常，在新环境中工作比更改root更安全.但是，在尝试更改之前，请考虑备份现有环境.通过在演示环境中测试这些命令来验证所需的结果.例如，要备份您的root env:

Normally it is safer to work from a new environment rather than changing root. However, consider backing up your existing environments before attempting changes. Verify the desired outcome by testing these commands in a demo environment. To backup your root env for example:

λ conda activate root
λ conda env export > environment_root.yml
λ conda list --explicit > spec_file_root.txt

选项

选项1 -YAML文件

在第二个环境(例如myenv)中，

Within the second environment (e.g. myenv), export names⁺ to a yaml file:

λ activate myenv
λ conda env export > environment.yml  

然后更新带有Yaml文件的第一个环境 ⁺ (例如root):

λ conda env update --name root --file environment.yml     

---

选项2 -克隆环境

Option 2 - Cloning an environment

使用 --clone 标志以克隆环境(请参见@DevC的帖子):

Use the --clone flag to clone environments (see @DevC's post):

λ conda create --name myclone --clone root

这基本上创建了环境的直接副本.

This basically creates a direct copy of an environment.

选项3 -规范文件

制作

Make a spec-file⁺⁺ to append dependencies from an env (see @Ormetrom):

λ activate myenv
λ conda list --explicit > spec_file.txt
λ conda install --name root --file spec_file.txt

或者，复制一个新环境(推荐):

Alternatively, replicate a new environment (recommended):

λ conda create --name myenv2 --file spec_file.txt

^{+ Conda文档已更改；链接已更新. ++ 规范文件仅适用于在同一OS上创建的环境.与前两个选项不同，spec文件仅捕获指向conda依赖项的链接.不包括点子依存关系.}

^{+Conda docs have changed since the original post; links updated. ++Spec-files only work with environments created on the same OS. Unlike the first two options, spec-files only capture links to conda dependencies; pip dependencies are not included.}
