Suppose your project has the following structure and you want to do imports in the notebook.ipynb:

/app
  /mypackage
    mymodule.py
  /notebooks
    notebook.ipynb

If you are running Jupyter inside a docker container without any virtualenv it might be useful to create Jupyter (ipython) config in your project folder:

/app
  /profile_default
    ipython_config.py

Content of ipython_config.py:

c.InteractiveShellApp.exec_lines = [
    'import sys; sys.path.append("/app")'
]

Open the notebook and check it out:

print(sys.path)

['', '/usr/local/lib/python36.zip', '/usr/local/lib/python3.6', '/usr/local/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages/IPython/extensions', '/root/.ipython', '/app']

Now you can do imports in your notebook without any sys.path appending in the cells:

from mypackage.mymodule import myfunc

Jupyter is base on ipython  a permanent solution could be changing the ipython config options   Create a config file    ipython profile create   ipython locate  Users username  ipython   Edit the config file    cd  Users username  ipython   vi profile default ipython config py   The following lines allow you to add your module path to sys path  c InteractiveShellApp exec lines          import sys  sys path append   path to your module        At the jupyter startup the previous line will be executed  Here you can find more details about ipython config https   www lucypark kr blog 2013 02 10 when-python-imports-and-ipython-does-not
