Hello,
I am trying to play soundfiles (.wav) through a loop. The soundfiles work perfectly fine if i type them in directly, but if i want the loop to put in the soundfiles with an Excel file I get an Error:
“value error: nonbrodcastable output operant with shape (128,1) doesn’t match the brodcast shape (128,2)”
This is the code shown in the script:
#!/usr/bin/env python
-- coding: utf-8 --
“”"
This experiment was created using PsychoPy2 Experiment Builder (v1.90.2),
on Juni 02, 2018, at 11:02

I am using Psychopy Standalone version 1.90.2 on Win10.
This is the full error message:
(I have selected the Set every repeat option for a variable parameter to my Component and there is no typo in the name)
