OpenSesame 3.2- 'Float' error running "Visual world" tutorial

Dani.rnc

Hello!
I am trying to run the "Visual world" experiment, which I downloaded (https://osf.io/z27rt/).
I keep on getting this error message: 'float' object cannot be interpreted as an integer.
Here is the script in the debug window:

Python 3.6.4

* Type "help()", "copyright()", "credits()" or "license()" for more information.
* Use the "print([msg])" function in inline_script items to print to this debug window.
* Inspect inline_script variables when an experiment is finished.


Starting experiment as ExperimentProcess-1
openexp._canvas.legacy.init_display(): enabling hardware surface
openexp._canvas.legacy.init_display(): enabling double buffering
openexp._canvas.legacy.init_display(): video mode ok
openexp.sampler._legacy.init_sound(): sampling freq = 48000, buffer size = 1024
openexp.sampler._legacy.init_sound(): mixer already initialized, closing
experiment.run(): experiment started at Thu Feb  1 13:26:19 2018

Can anybody help?

Hi Daniela,

PyGaze is not yet compatible with Python 3, and you're using the Python-3-based package of OpenSesame. So simply grabbing the Py2 package should solve this!

Cheers,
