Hi! We’ll need more information before we can help you, ideally enough to reproduce your problem.

Have a read through

Hi @manics , sure thing.

I facing that in a terminal instance within the jupyterhub I have a set of python packages installed that are not passed to the kernel of notebooks of the same users of the jupyterhub.

I cannot install via pip e.g., pip install in the terminal instance, since I get this error message:

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

but I can install via the notebook using !pip install .

So, my guess is that there are two kernels one is used in the notebooks and one is used in the terminal.

What if you use %pip install via the notebook? (Which is what you should be using inside a running notebook in modern Jupyter these days, since 2019. I know the TLJH is still using old tech, but I think that is what you should be using.)
