If this template helps then use it. If not then just delete and start from scratch.
Mac OS X : 10.12.6
PsychoPy version : 1.90
**Standard Standalone? ** : yes
I am trying to insert a code snippet into my experiment to rotate gratings using iohub, but before I can get anything to run the program stops with an error message:
from psychopy.iohub import launchHubServer, EventConstants
ImportError: cannot import name EventConstants
Any help would be appreciated! Thank you.
