What did you try already?

1) run

import pip

pip.main(['install', 'numpy', '--upgrade'])

2) complete re-install of OpenSesame 4.1.7

Hi @LukasKunz,

Have you tried reinstalling Opensesame in a new environment with Conda, or did you install it using the standalone package? You could also try switching the backend to Psycho. Alternatively, if you want a quick workaround, you could create the condition table externally (e.g. in Excel) and paste or import it into the loop without using the full-factorial wizard. 

If you still get the error, could you share your experiment file so that I can take a closer look?

Thanks,

Claire
