OS 3.3 + Tobii

jsneuro

Hi all,

With the new updates regarding OSweb I started using OS 3.3, but some of my other programs no longer work with a Tobii eye tracker. When trying to use the eye tracker it throws this error: AttributeError: module 'tobii_research' has no attribute 'find_all_eyetrackers'.

The issue is probably due to my old OS using Python 2.7, and the new version using 3.7.6 (which is not supported by the Tobii SDK), while the Tobii SDK does not support Python 3.7. Is there a way to use Python 2.7 or 3.8 with OS 3.3?

I tried installing the version on the Download page which supposedly uses an older version of Python, but it threw a long list of errors, and actually was unable to run at all.

So any workarounds or tips are appreciated!

Hello, I am also following this question, as I have the same problem!

[It would be nice to know that Tobii and OpenSesame at some point will converge together in more recent python versions, as this would enable using the latest functionalities (and indeed basic ones, such as PsychoPy as back-end). Will OS adopt python 3.8 or it will skip to 3.9 directly? (Just asking, I know you guys don't work miracles, :) ]

There is a fair chance you can update Python to 3.8 and still be able to use Opensesame. So, I guess that would be easiest option to try out. Starting Opensesame on top of Python2 could also still work, I don't know how, though. @sebastiaan is that still possible?

Hi @eduard , @jsneuro , and @EBlini ,

Your best bet is probably to create a Python 3.8 environment with Anaconda, and then install OpenSesame in there. OpenSesame is compatible with all recent versions of Python, including Python 3.8.
