Issue running the code

I am trying to follow the run instruction on the readme but I keep getting the following error:

Franks-MacBook-Pro:shortest-path frank$ pipenv run ./train.sh

To run this I just deleted everything related to Anaconda and brew re-installed python3.6.5, but I still keep getting this error. Would love some help.

Never mind, I had to delete the existing folder to make it work.
