Naive_Bayes Mini-Project: nb_author_id code error

[okoriechinonso1]

Hi,
thanks so much for simplifying and getting the codes to work on jupyter notebook virtual environment. I am using your files and my virtual environment has been set up successfully and running. However, I am trying to run the notebook file for the naive bayes classifier project but I keep getting this error. What can be done to fix this:
