'type' object is not subscriptable

Hi,

I encountered this error:

(vibrant) e2s2@e2s2-super-server-1:~/Softwares/VIBRANT$ python3 VIBRANT_run.py -h
Traceback (most recent call last):

TypeError: 'type' object is not subscriptable

Anyone knows how to solve it? Many thanks!

I'm not sure what the issue is but my guess is there is a version issue. At the time of writing VIBRANT python >=3.5 and any matplotlib seemed to work. I'd suggest creating an environment with python v3.7 as an example and see if that works.

I've solved this problem myself by downgrading the pyparsing package to 2.4.7.
