在 `environment.yml` 中设置环境变量 [英] Set environment variables in `environment.yml`

问题描述

我可以在 condaenvironment.yml 文件中设置环境变量吗> 环境?

Can I set environment variables in environment.yml files in conda environments?

Conda 让我 在环境中保存环境变量 通过 env_vars.sh 脚本，但是有没有办法自动化在 activate.d 中创建 env_vars.sh 文件的过程code>, deactivate.d 目录根据 environment.yml 中的一些环境变量规范，用于可重现的环境，例如 MKL_THREADING_LAYER=GNU?

Conda lets me save environment variables in environments via the env_vars.sh script, but is there a way to automate the process of creating env_vars.sh files in the activate.d, deactivate.d directories according to some specification of environment variables within environment.yml, for a reproducible environment with, say, MKL_THREADING_LAYER=GNU?

推荐答案

好像是在Conda v4.9中添加的！

It looks like this was added in Conda v4.9!

使用 conda env config vars 设置的环境变量将保留在 conda env export 的输出中.此外，您可以在 environment.yml 文件中声明环境变量，如下所示:

Environment variables set using conda env config vars will be retained in the output of conda env export. Further, you can declare environment variables in the environment.yml file as shown here:

name: env-name
channels:
  - conda-forge
  - defaults
dependencies:
  - python=3.7
  - codecov
variables:
  VAR1: valueA
  VAR2: valueB

旧版本的 conda 会报错；

Older versions of conda will complain;

EnvironmentSectionNotValid: The following section on 'environment.yml' is invalid and will be ignored:
 - variables
