'Pygaze_trackertest' doesn't work correctly.

rrr · October 2015

Hello,

I get errors of pygaze (0.6.0) in MacOS using Eyelink1000plus.
When I started 'Pygaze_trackertest.py' of the examples, it caused two errors.

[Calibration and Validation errors]

As I did the calibration and validation, it started but didn't presented a black fixation at the displayPC. The monitor of displayPC kept a gray blank and I was not able to see the black fixation, while the hostPC showed the screens of calibration and validation correctly (actually record the eye movements).

WARNING: screen.Screen: could not find font '/Users/Desktop/PyGaze-prerelease-0.6.0a1/examples/pygaze_trackertest/fonts/mono.ttf'; using default instead

Traceback (most recent call last):

NameError: global name 'EYELINKCALBEEP' is not defined

[Can't end the file]

I was not able to end. When I pressed 'esc' and 'y' to end, it froze. I had to do the forced termination.

What is cause?

Best,

Hello,

I encountered new errors.
I updated the pygaze version from 0.6.01a to 0.6.04a, and run new 'Pygaze_trackertest.py' of the examples. It showed errors as below.

My Eyelink didn't work when I run it, while this program worked half way.
It froze when I tried to start the drift correct according to the instructions.
