Psychopy crash upon opening (MacOS 10.15.7)

Hi everyone,

Psychopy 2020.1.2 was installed under a conda environment (using anaconda). It worked well until these two days I tried to install the latest psychopy version under another conda environment. In theory it should not affect the original psychopy environment, and I have also confirmed that it has never been changed. However, whenever I initiate the program in command line, the program crushes right after the “creating frame” text appeared on the PsychoPy banner.

Why would it happen? I don’t want to lose the access to all my existing experiments!!
Helps are much appreciated!

This is the error message on the terminal

I guess that the Segmentation fault: 11 is the problem, as all the preceding messages appeared as well when the psychopy was working.

I have also updated the conda version (4.10.1 → 4.10.3) in the past two days, but this error persist even I have reverted the conda version to 4.10.1.

Could anyone answer my question? Any helps are much appreciated.

Hi There,

Possible longshot (I am coming from windows myself so let’s see if this works!) after you launch from command line, I expect you will see the PsychoPy logo on the taskbar at the bototm of the screen? (then you see a window frame that crashes?) - if you click the bouncing psychopy icon does that move forward to opening the software?

Becca

Thank you for your reply @Becca! But the logo isn’t clickable, unfortunately.

Ah I also just clicked the version you mentioned! Is there a reason to be using the 2020 version rather than 2021? (so often an update resolves bugs like this!)

As @Becca mentioned, it’s recommended that you keep PsychoPy updated on MacOS since Apple frequently makes changes which cause breakage.

hi,
Trying to install psychopy, in a conda environment python 3.6. (doing this many times with student on several OS version etc…)
but this time the script crashes when calling gui function.
no error message, nothing just a kernel interruption at the same line (Jupyter)
any idea ?
