OpenSesame crashes on Ubuntu 16.04

Dear forum,

I'm trying OpenSesame for the first time but unfortunately I'm running into problems with the eye-tracking template which consistently crashes on my Ubuntu install.

I did the following:

  • Install OpenSesame through the PPA on Ubuntu 16.04 (current LTS release).
  • Start OpenSesame in a terminal.
  • Choose backend PsychoPy.
  • Start experiment by clicking the play button.
  • Enter subject ID.
  • Select file name.

The screen turns black for ~500ms and then I'm back in the OpenSesame GUI where I see the following error message:

Stopped

The experiment did not finish normally for the following reason:

Unexpected error

  File "/usr/local/lib/python2.7/dist-packages/numpy/core/numeric.py", line 192, in ones
    a = empty(shape, dtype, order)
TypeError: 'float' object cannot be interpreted as an index

At first, I thought that the template can perhaps not be run without changes but it does run on my colleagues Windows machine. Any advice on how to fix this issue?

  • Hi,

    Yes, this is an incompatibility between certain versions of numpy and OpenSesame. It's been fixed in the unstable releases of 3.1.7. You can install those from the opensesame-james ppa:

    sudo add-apt-repository ppa:smathot/opensesame-james
    sudo apt-get update
    sudo apt-get dselect-upgrade
    

    Of course, this is a testing repository, so proceed with caution!

    Cheers,
    Sebastiaan

  • I get the following error message. Would there be a simple way to solve this? This is in Ubuntu 15.04 after installing the latest version (Nov 2017).

    Hi Frouke,

    It looks like you have an old version of QProgEdit installed, which doesn't work with PyQt5. You can upgrade by running:

    pip install python-qprogedit
    

    Does that solve things?

    Cheers,
    Sebastiaan

  • Unfortunately, the problem persisted after installing the indicated software. I decided to upgrade to Lubuntu 16, 64 bits (clean install), and under this new version, the problem no longer occurs.
