This has been answerd in this post: don't use ! before pip command because it is executed as in command line, instead use the % sign to execute inside the virtual evironment of the current ipython kernel.

Understand these two functions, and your problem will be solved.

# List the current work directory
os.getcwd()

# Change the current work directory
os.chdir()

Change the path, and import module, and have fun.

Sometimes it won't work. Try this:

import sys
# 'sys.path' is a list of absolute path strings
sys.path.append('/path/to/application/app/folder')

import file

I was having a similar issue. I installed a text processing tool using pip3. The installation was successful and I was able to run the test-code from the terminal, however I was unable to execute the same code from jupyter notebook. Checked that the sys.version was 3.7.1 in notebook but the terminal version was 3.6.9.

The problem was resolved after executing the following commands and relaunching the notebook:

pip3 install ipykernel --upgrade
python3 -m ipykernel install --user

If the package is installed sucessfully, you can add the path where the package is located either as an environment variable or in your notebook.

import sys
sys.path.append('/anaconda3/envs/gdd/lib/python3.7/site-packages')
