OS: Win 10  
PsychoPy version: v2020.1.3

**What am I trying to achieve:**

I am trying to integrate Tobii Eyex eye-tracker and Psychopy, but the calibration process does not work as expected.

I initialized the experiment with this block of code in “Begin experiment”, like the documentation indicates:

_from psychopy.iohub import launchHubServer_  
_from psychopy.core import getTime, wait_

_iohub\_config = {‘eyetracker.hw.tobii.EyeTracker’:_

- {‘name’: ‘tracker’, ‘runtime\_settings’: {‘sampling\_rate’: 120}}}\*

\*io = launchHubServer(\*_iohub\_config)_

_# Get the eye tracker device._  
_tracker = io.devices.tracker_

_# run eyetracker calibration_  
_r = tracker.runSetupProcedure()_

_# Check for and print current eye position every 100 msec._  
_stime = getTime()_  
_while getTime()-stime \< 5.0:_

- print(tracker.getPosition())\*
- wait(0.1)\*

_tracker.setRecordingState(False)_

_# Stop the ioHub Server_  
_io.quit()_

Unfortunately, does not works. The calibration screen appears but does not offer the calibration process when i press ‘space’ and the stdout was:

##### Experiment ended.

**What did i try to make it work?:**

I’ve tried to manage different python versions and different psychopy3 versions, but nothing seems to work
