Error when connecting to Tobii eyetracker

Hi! @yujia

I have the same error message when connecting Tobii to psychopy. (latest version 2023.2.3, but the older version was fine)

I wonder if the code you modified are the below ones or somewhere else? (below seems correct for me)

    # Setup eyetracking
    ioConfig['eyetracker.hw.tobii.EyeTracker'] = {
        'name': 'tracker',
        'model_name': 'Tobii TX300',
        'serial_number': '',
        'runtime_settings': {
            'sampling_rate': 60.0,
        }
    }
