In general, if you are using a Python virtual environment on k8s, you should only modify it from a shell in a matching k8s container. The easiest way to do this is with `webservice --backend=kubernetes python3.9 shell` (or whatever version you are using). If the python version you're using matches what's in use on the Buster bastion, it should work, but using a k8s shell will be the most reliable.

You can use the one used for k8s on the bastion too, the thing is that the k8s environment expects it to be in a specific path, that is `$HOME/pyenv/`.
Now, that might not work if the python version in the bastion is too different from the one the k8s job has, so you might have to have two different ones in that case yes (bastions are restricted to the python version of the OS, the k8s jobs can use different ones depending on the image).

Hello everyone,
Thanks for the suggestion. Does this mean that I have to maintain 2 virtual environments (one for bastion and the other one for k8s pod my code will actually run in)?

Hello,
I just received a dozen emails about grid engine migration. I tried to migrate my personal tool (tool.martin-urbanec) first. This tool currently generates a Jupyter-notebook based report daily.
I do that by calling jupyter nbconvert --to html --execute community_configuration_usage.ipynb from a virtual environment where Jupyter is installed, together with a couple of other Python modules.
I managed to create new virtual environment that works from the new Buster bastion, and it works when executed directly from the bastion, but I can't get it to execute via the k8s-based engine:
Your problem may be related to bootstrapping the venv. See if this information can help you:

This is very similar to what JMC89 replied in the other email.
