Error running the script

[eperezv]

Hello,

I am trying to run the script but I got an error during the process. I am just running this "python3 analyze_papers.py My_Library_v2.csv" on Ubuntu 20.04 after installing the dependencies (i.e. pdfminer and so).

The above exception was the direct cause of the following exception:

    result = pool.map(list_worker, list(titles_dict.items()), chunksize=5)
