Stimulus Presentation Create Design Matrix Error

[bvkennedy]

I am receiving an error when I run create_design_matrix.py with the default values entered.

Here is the full error message:

Running: C:\pyprf-master\pyprf\stimulus_presentation\code\create_design_matrix.py

It's hard to guess what may have gone wrong from the traceback alone. If I remember correctly, the easiest way to create a design matrix is to run /pyprf/pyprf/stimulus_presentation/code/create_design_matrix.py is Psychopy. I would recommend to try different Psychopy version. If possible try Psychopy version 1.83.04.
