When I run the following commands

(py3env)manzuoni KingJamesProgramming  17:10:21 $ python3 markov
(Cmd) train 3 --noparagraphs /Users/manzuoni/hax/KingJamesProgramming/train
(Cmd) tokens 350

markov exits with an error:

I just hit this error, my problem turned out to be that train expects a shell glob, not a directory name, I had to add a /* to the end of the path argument to get it to pick up all the files

Ah makes sense. It was indicated in the README but I missed that part. Thanks a bunch
