macOS Mojave 10.14.5
PsychoPy version: v3.1.2
Standard Standalone? (y/n): Yes
I created an experiment on the Builder view. It has two parts: One is silent, the other is Music part. I work with babies so I need to record babies looking behaviour during the experiment.
So, I also added the keyboard code (someone suggested on the forum):
from psychopy.hardware import keyboard from psychopy import core kb = keyboard.Keyboard() # during your trial kb.clock.reset() # when you want to start the timer from keys = kb.getKeys(['right', 'left', 'quit']) kb.start() if 'quit' in keys: core.quit() kb.stop() for key in keys: print(key.name, key.rt, key.duration)
Everything was good until the second part. There is a WARNING sign says:
78.7266 WARNING Stopping key buffers but this could be dangerous ifother keyboards rely on the same.
Could anyone say me what does it mean, please? Do you think I have same technical issue in my computer rather than the PsychoPy.
