Can a Jupyter notebook load

python_library

into a notebook? I am able to load

pex_binary

(and other binary targets are documented to be supported). However, what about loading plain sources? My ultimate goal is to be able to write

from projectA.module import function

in Jupyter (because

projectA

is on the

sys.path

).

This is likely out of date, but you might try / improve: https://github.com/pantsbuild/pants-jupyter-plugin

@enough-analyst-54434 do you mean it’s not currently possible, but there is a chance that it will be possible if one extends the plugin? 🙂

I mean I'm just not sure. We had a spate of renaming (python_library -> python_sources) and I'm unsure how this or other refractors may have affected that project.

sure, sure! Thanks @enough-analyst-54434

It looks like it works with Pants 2.8.0 but I forgot the plugin only works for pex_binary targets; not python_library / python_sources.

great that it works with a newer versions of Pants! Yes, that’s the problem that it only works against

pex_binary

; there is a need to be able to work with the monorepo without packaging everything. Jupyter notebooks work great OOTB in VScode thanks to the

.env

file I mentioned earlier and in PyCharm thanks to the directories marked as sources. You can just run

from projectA import foo

with any of the the monorepo directories, so it’s alright. So I wouldn’t worry too much about Pants plugin support for

python_library

— it’s essentially unnecessary given how easy it’s to change the

PYTHONPATH

before starting the

jupyter lab
