Errors in pygaze examples code

Shri

Hi,
I took pygaze examples code and trying to see the outputs. But I am ending up with errors
https://github.com/esdalmaijer/PyGaze/tree/master/examples/slideshow

The "experiment.py" code from the above link with python 2.7.5 32-bit gives the error as,
Participant name: "sindhu"
Traceback (most recent call last):
File "E:\pygaze\PyGaze-master\examples\slideshow\experiment.py", line 25, in
disp = Display()
File "C:\Python27\lib\site-packages\pygaze\display.py", line 45, in init
self.class.init(self, **args)

File "C:\Python27\lib\site-packages\psychopy\visual\window.py", line 237, in __init__
self.scrWidthCM = self.monitor.getWidth()
AttributeError: 'NoneType' object has no attribute 'getWidth'

The same code experiment.py with python 2.7.15 32-bit gives the error as,
Participant name: "sindhu"

I don’t have any hardware and eyetracker. I just want to see the output of Heatmaps, fixations and scanpaths. How it can be possible? How these errors can be rectified?

Thanks & Regards,
Shri

Hi All,
Please kindly reply me. I don't have any eyetracker and I want to see the outputs for heatmaps and fixations. Explain me the steps to get the output and do help me with my errors.

Thanks&Regards,

Hi Shri,

From your output, it's clear that you are trying to run the "slideshow" experiment script with the TRACKERTYPE set to eyelink. This will not work, because you say you do not have an EyeLink, and because (as the error message indicates) you have not installed the library pylink (which would be required for working with an EyeLink tracker.

Finally, you are also using the wrong software. What you are running is an experiment script, but what you say you want to do is use PyGaze Analyser functionality. For this, I would like to refer you to your other question, where you have been pointed to example gaze data files.

Regards,
Edwin

PS. In both this and one of your other questions, you have posted a question on 2 January, and followed this up with a request to urgently reply on 3 January. Everyone here volunteers there time next to at least a fulltime job, which makes it unlikely that we respond very quickly.
