Python environment does not activate in a terminal

I tried activating a specific python environment in a terminal using the command:

source $ENV_DIR/sas/bin/activate

and I get the following error:

bash: /opt/envs/sas/bin/activate: No such file or directory

I tried this with a few other python environments (heasoft, ciao, fermi) and I got the same error for each of them.

Never mind, I figured it out. The documentation isn’t clear that the environments ‘sas’, ‘heasoft’ need to be activated using

micromamba activate {env-name}

Docs are being updated to clarify this.

I have some suggestions for a little more extensive update.
