PsychoPy version: 2023.2.2

I previously solved the Error “WARNING: pytables package not found. ioHub functionality will be disabled”, which prevents ioHub to start by following downgrading numpy to an older version.https://github.com/psychopy/psychopy/issues/5876
Not sure if that relates to the later error message.

I wanted to connect Tobbi fusion with PsychoPy, and have downloaded the tobbi eyetracker plugins.

but got the following error message:

Error during device creation ....

I listed all files in the directory, no such .yaml

I found in the previous version, there is a .yaml file

But the 2023.2.2 does not

3

Add the appropriate eye tracker as a plugin from Tools → Plugin/packages manager

4

Yes, I did. But still got the error message

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.
