AttributeError: 'NoneType' object has no attribute 'get' in eyetracking calibration

Hi Kim,

Thanks for the reply.
The info that I put in Settings are
device: Tobii Pro Fusion
rate: 120

The other settings are optional, I have tried to put down the serial number, but still the error message.

FYI, I have tried to connect Tobii Pro Fusion with PsychoPy in the past few weeks. I have reported on PsychoPy Github page on the issues that I encountered. For example, these two issues (links below) have been resolved in the most recent release (2023.2.3). But the first issue “no such file default_eyetracker.yaml”, in the 2023.2.3 release, the yaml file is uploaded, but not in the correct directory. It should be ‘C:\Program Files\PsychoPy\lib\site-packages\psychopy\iohub\devices\eyetracker\hw\tobii\default_eyetracker.yaml’, which I manually moved the files to. Then I got another error message stated in the post.

Currently, I have downgraded to PsychoPy 2023.1.8, which is the version before making Eyetrackers as plugins. It worked fine with my experiment (with the same setting).

[Errno 2] No such file or directory: \default_eyetracker.yaml

I was able to solve the problem by downloading the default_eyetracker.yaml and supported_config_settings.yaml (which is also missing from the current version) from an older version here versions/psychopy/iohub/devices/eyetracker/hw/tobii at master · psychopy/versions · GitHub No more error message.

Eyetracking Calibration stimuli won't show up

OS (e.g. Win10): Win10 PsychoPy version (e.g. 1.84.x): 2023.2.2 I have been experiencing issues using Tobii Pro Fusion in PsychoPy. Previously, PsychoPy threw error messages saying “couldn’t find default_eyetracker.yaml …” I solved the problem, see [Errno 2] No such file or directory: \default_eyetracker.yaml - Builder - PsychoPy . This may or may not relate to the problem I’m facing now. So, I finally get the eye tracker up and running, and I created a simple calibration routine (no customiz…
