问题描述
我可以在 conda 环境中的environment.yml文件中设置环境变量吗?
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，但是有一种方法可以根据environment.yml中某些环境变量的规范自动在activate.d，deactivate.d目录中创建env_vars.sh文件.具有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
当前状态(Conda v4.7.12)
否，无法在env YAML中设置特定于env的环境变量.
Current Status (Conda v4.7.12)
No, it is not possible to set env-specific environment variables in an env YAML.
正如@Ben在评论中指出的那样，这是一个开放功能请求 .尽管从技术上讲它没有设置里程碑，但引用此问题的拉取请求是作为里程碑Conda v4.8.0的一部分进行了合并，看起来好像它为env特定的环境变量(即，无需手动编写激活钩子)提供了一些基础结构.例如，PR添加了一个conda-env命令vars，该命令可以像
As @Ben pointed out in comments, this has been an open feature request. While it technically doesn't have a milestone set, a pull request referencing this issue was merged as part of milestone Conda v4.8.0 that looks like it provides some infrastructure for env-specific environment variables (i.e., without manually writing activation hooks). For example, the PR adds a conda-env command vars that can be used like
conda env vars set MKL_THREADING_LAYER=GNU
但是，我找不到用于从YAML解析vars的代码，也找不到用于将vars导出至YAML的新代码(但是，我只能略过它-主要是查看添加的测试).
However, I could find neither code for parsing vars from a YAML nor new code for exporting vars to a YAML (but, admittedly, I only skimmed through it - mainly looking at the tests that were added).
总而言之，最终答案仍然尚未，但是可能很快就会出现.
In summary, the final answer is still not yet, but it could be on the horizon.
