'Window' object has no attribute '_closed'

I am getting the following exception multiple (Several hundred) times while running experiments:

Exception AttributeError: "'Window' object has no attribute '_closed'" in <bound method Window.__del__ of <psychopy.visual.window.Window object at 0x25439610>> ignored

This creates a huge delay between operations and expirements.

Any assitance will be much appreciated.


  • Hi,

    That is a weird error. Can you share the experiment here? Have you tried a different backend? Maybe psychopy?
