Answer 1

This error occurs a lot. I would recommend using a virtual environment and then doing pip install fuzzywuzzy This is the most optimal and sure fire solution. The following are the instructions for creating and activating a virtual environment with venv:

Mac OS & Linux: How To Setup Virtual Environment

1) After cloning the repo, cd into the repo and run the command: python3 -m venv venv

    This will create the virtual environment. Make sure to name it venv because the .gitignore file
    has been initialized to ignore it by default. 

2) Activate the virtual environment by running the following command: source venv/bin/activate

3) At any moment, you can run deactivate to leave the virtual environment.

Windows: How To Setup Virtual Environment

1) After cloning the repo, cd into the repo and run the command: python -m venv venv

    This will create the virtual environment. Make sure to name it venv because the .gitignore file
    has been initialized to ignore it by default. 

2) Activate the virtual environment by running the following command: venv\\Scripts\\activate.bat

    To activate the virtual environment inside of a code editor's bash, run: venv\Scripts\activate.ps1

3) At any moment, you can run deactivate to leave the virtual environment.

Compare sys.executable and sys.path in shell vs notebook. Are you running the same interpreter, with same site packages location? – Amadan Jul 17 '19 at 5:32

This was the answer for me! I have copied the sys.path results from my shell to assign sys.path within the notebook like this:

sys.path = ['list-of-paths-from-my-shell']

Then, it solved!

Bingo.
