[Modules] environment modules for Conda environments

[Marius R. <mar...@es...>]

Dear all,

First of all happy new year and best wishes for 2022!

I would like to use environment modules to load/unload Conda environments (https://docs.conda.io/projects/conda/en/latest/user-guide/getting-started.html#managing-envs <https://docs.conda.io/projects/conda/en/latest/user-guide/getting-started.html#managing-envs>).

I have a working environment module for Conda alone. Now I need a module for a specific Conda environment. For this I use the code below to load/unload the environment:

## My conda environment module file

module load conda

if { [module-info mode load] || [module-info mode switch2] } {
    puts stdout "conda activate $path"
} elseif { [module-info mode remove] && ![module-info mode switch3] } {
    puts stdout "conda deactivate"
}

If I do module load my_conda_environment; module unload my_conda_environment, I get an error because the conda dependency is unloaded first and then the conda command is not found anymore. 

However this works: module load conda; module load my_conda_environment; module unload my_conda_environemt; module unload conda. 

Is there a way to have the result of the previous line, without having to explicitly load conda? Thank you for your help.

Best regards,
Marius
