Experiment is crashing regularly

edited May 2018 in OpenSesame

Good evening.
We have designed an AB-Experiment which is unfortunately crashing in more than 50% of the times. What can we do?

Thanks and best regards,


  • Hi Cruella,

    This error means that Python itself (rather than the experiment) crashes, usually due to a bug in one of the underlying libraries. It's not something that you're doing wrong, in other words.

    The reason for such crashes can be quite obscure, but they can generally be traced back to a specific thing that happens during the experiment. So I would start by figuring out when the experiment crashes, for example by including print() statements to pinpoint when the program dies. And then see if you can figure out the culprit.


    There's much bigger issues in the world, I know. But I first have to take care of the world I know.
