i try to launch the example code from psychoPy web site:
from psychopy import visual, core win = visual.Window([400,400]) message = visual.TextStim(win, text='hello') message.autoDraw = True # Automatically draw every frame win.flip() core.wait(2.0) message.text = 'world' # Change properties of existing stim win.flip() core.wait(2.0)
i have one error with pyglet and i have to downgrade it and it seems OK.
But Second bug :
raise AssertionError(‘XF86VidModeGetGammaRamp failed’)
AssertionError: XF86VidModeGetGammaRamp failed
i try the solution from djmannion: https://github.com/psychopy/psychopy/issues/2061#issuecomment-428792028
However the problem is not solved.
