Had the same issue, this is because multiprocessing does not work natively inside a Jupyter notebook. For details see this StackOverflow discussion (specifically Eden Trainor's answer):
https://stackoverflow.com/questions/48846085/python-multiprocessing-within-jupyter-notebook
Apparently someone has created a similar library to multiprocessing called multiprocess which works inside jupyter notebooks. However, I suggest the authors (@azai91) either put a !pip install multiprocess in the notebook for this, or add a comment saying to run it from an IDE like Spyder. Since the multiprocess library has its own problems (had to re-import numpy inside the process) probably would go for the latter option.
