AttributeError: 'PygletBackend' object has no attribute '_isFullScr'
in OpenSesame
Hi,
I am trying to implement an old behavioral experiment of mine using Open Sesame in a different lab, but I get this error:
AttributeError: 'PygletBackend' object has no attribute '_isFullScr'.
Do you have any idea why it is the case?
Thank you in advance for any help,

Hi @MicolG ,
This sounds like a version incompatibility. Is a different version of OpenSesame running in this lab? Or perhaps people have installed OpenSesame manually (for example through Anaconda), in which case the version of Pyglet, which is one of the underlying Python libraries, may be incompatible.

Hi @sebastiaan,
Sorry for the late answer.
In this lab, they had not used Open Sesame by the time I got here, so I manually installed that myself.
Did I do something wrong? Do you suggest me doing something different?
Otherwise, I should use another software, but I am positive that I can fix the issue.
Thanks,
@MicolG How exactly did you install OpenSesame? And can you post the full error message, including the traceback? You can find this in the Jupyter console.
