Apologies for reposting, but I still can’t figure out why the error randomly pops up, even when I do the exact same things (as far as I can tell). I cannot schedule participants in advance because of this!
I am running an experiment where people see a stimulus for at least 60 seconds. After the 60s are over, they can exit the screen by pressing SPACE any time they want to (I have put an upper bound at 300s). Only 3 key inputs are legal, ‘left,’ ‘right,’ and ‘space.’
However, within the first 60s itself, I get a popup error: ‘Python.exe has stopped responding.’ I have updated Psychopy to the latest version (v2023.2.2), and I am using a Windows 10 system (however, the same error occurs on Windows 11, too). The rub is that this happens only occasionally. It also happens when I do not have any other program running, so RAM is not an issue. I suspect it is because I am running 2 loops, but I cannot figure out how else I can code this or why it only happens sometimes.
from psychopy.visual import TextStim, ImageStim, Slider, RatingScale, ShapeStim from psychopy import core, visual win = visual.Window((800, 650)) kb = keyboard.Keyboard() trial = [1, 2, 3, 4, 5, 6, 7, 8] trial_start = core.getTime() #screen details def imagine(screen = 1, trial = trial, num = 0): if screen == 1: TextStim(win, text = "first screen").draw() win.flip() else: TextStim(win, text = "second screen").draw() win.flip() return 'Imgine screen' i = 1 imagine(screen=1, trial = trial, num = i + 1) trial_onset = core.getTime() - trial_start delib_keys, delib_rt = ,  kb.clock.reset() keys = kb.getKeys(['left', 'right', 'space']) while kb.clock.getTime() < 300: if keys: for key in keys: delib_keys.append(key.name) delib_rt.append(key.rt) if (kb.clock.getTime() > 60): imagine(screen = 2, trial = trial, num = i + 1) if ('space' in keys): break print(delib_keys, delib_rt) win.close() core.quit()
The error looks like this and freezes the experiment. There is no error in the runner.
