Opensesame error: ImportError: No module named psycho

Serehal

Hi all,

I am running an experiment with opensesame 3.2.4 version on a pc with Ubuntu 16.04.5 version.
Everything worked until today (I already run 42 participants); what happened is that when I started opensesame today, it reported this error:

Starting experiment as ExperimentProcess-8
experiment.end(): missing or invalid log object
An Exception occurred during exp.end(): No module named psycho

Unexpected error

item-stack: 
exception type: ImportError
exception message: No module named psycho

ImportError: No module named psycho

Does anyone can help me with this?
Thanks in advance.

Hi Serehal,

This sounds like the OpenSesame package has been corrupted for some reason, possibly due to some problem with the package manager.

As a first step I would simply reinstall opensesame:

sudo apt-get install --reinstall opensesame

Does that resolve the issue?

Cheers,

Hi Sebastiaan,

thanks for your advise, but it did not work. This morning we disinstalled all versions of opsensesame installed in that pc and reinstalled the one we are using and now it's working. Thank you very much anyway!
