You can use Tobii Pro Eye Tracker Manager for the calibration.
Once you calibrate subject's eyes, the parameter is saved in the eye tracker internally.

In PsychoPy editor, select the experiment in this repo and the run it.

Run ./tools/gaze_analyzer.py to draw the eyes' tracing

Any sampling rate is OK when you calibrate subject's eyes.
