Summary

I cannot use elpy-goto-definition for my own modules when editing Jupyter notebooks.

Steps to reproduce

Say I am in Python project (you may clone it from https://github.com/xiaohan2012/test-goto-def) and wrote my own library mylib:

.
├── main.ipynb
├── main.py
└── mylib
    ├── __init__.py
    └── module.py

where module.py contains:

def func():
    pass

and main.py and main.ipynb contain the same:

import numpy as np
from mylib.module import func

Now I want to use elpy-goto-definition of func and np in both main.py and main.ipynb

It does not work when looking up func in main.ipynb

But it works for the remaining cases: looking up func in main.py and np in main.ipynb
