Open Gorana7 opened 3 years ago

Gorana7 commented 3 years ago

hello,

I've beeb using a python 2.7 environment using Conda and jupyter notebook. I can't load the data data = hddm.load_csv ('./cavanagh_theta_nn.csv')

I get the error message IOError Traceback (most recent call last)

I've tried to make my own csv from the GitHub data, but that didn't work. I don't know how to ask python to use the GitHub directory to carry this out either. I have 0 python/coding experience.
