Calibration not running when call calibrate in Psychopy using Pygaze and Eyelink

Hi,

I have been trying to develop and run a simple eyetracking experiment on a windows computer using an eyelink 1000+ system in the builder mode provided by psychopy. I have been running into an issue in terms of getting the program to execute the calibration before the experimental trials begin.

Although it seems to open a window to perform the calibration on the stimulus computer nothing appears (neither menu nor fixation dots for calibration). I have tried pressing c, v, enter and q which are supposed to be the relevant key commands on the stimulus computer but nothing appears and it seems to be unresponsive. When I try starting the calibration from the eyetracking computer after the blank screen appears on the stimulus computer the calibration screen opens on the eyetracking computer (i.e. a fixation dot appears) but the screen on the stimulus computer remains blank and unresponsive. The code I have been using for the experiment came from the SimpleTrackerExperiment demo on the pygaze website and I added it right at the start of the experiment before any experiment instructions or trials begin:

import random import constants from pygaze import libscreen from pygaze import libtime from pygaze import liblog from pygaze import libinput from pygaze import eyetracker libtime.expstart() disp = libscreen.Display() tracker = eyetracker.EyeTracker(disp) keyboard = libinput.Keyboard(keylist=['space','c','v','q'], timeout=None) tracker.calibrate()

Also this is a copy of the constants.py file that is imported

DUMMYMODE = False # False for gaze contingent display, True for dummy mode (using mouse or joystick) LOGFILENAME = 'default' # logfilename, without path LOGFILE = LOGFILENAME[:] # .txt; adding path before logfilename is optional; logs responses (NOT eye movements, these are stored in an EDF file!)

Any help or suggestions would be greatly appreciated.
