Psychopy3 (2020.1.3 version, PY2, x86) crash upon opening (Windows7)

swann_pichon · August 3, 2020, 10:42pm

Hi there
I installed and desinstalled several time either the standalone version of psychopy3 (PY2) x86, or the standalone version of psychopy3 x86. In both cases I obtain a crash at startup, a few seconds after launching psychopy either trough command line or through the windows icon. The windows of the app get initialized then python crashes silently.

The python.exe process disappears from the task manager upon crash (aka no window is hidden)
My computer is a dell latitude laptop running W7 (graphic card intel HD 520, drivers uptodate)
I went through the troubleshooting page. Here is the content of the last_app_load.log file
I spent a couple of hours already reading all the “crash upon startup” entries I found in the forum to try different fixes but without any results unfortunately. I appreciate your help very much!

Still stuck - Any help appreciated very much

You could try 2020.2 which is now available to download.

swann_pichon · August 7, 2020, 2:13pm

Thanks a lot for the hint yet unfortunately 2020.2 also produces a crash error upon opening. Here is the output from the cmd window

Swann,

Did this get resolved? I have a study participant who cant run the online experiment off their Windows 10 Dell PC, my study has a mp4 video, and I was wondering if this might be because of the same problem.

Kind Regards,

swann_pichon · January 25, 2021, 1:36pm

Unfortunately it has not been resolved yet to my knowledge in the standalone version of psychopy3.

Now I was not aware that this problem could also impact experiment ran online, which seems problematic …

Tommaso_Fedele · March 15, 2021, 12:46pm

Hi there,
I was just wondering if there is any update on this issue. This is the latest conversation reporting problem to run Psychopy version 3 on Windows7.
It is possible that this conversation moved somewhere else and I miss it?

The error above looks like it will occur due to poor graphics card drivers. It mentions failing while trying to create the Pyglet “shadow window”. Obviously we don’t want the PsychoPy app to crash as a result, so that’s something we need to look into at our end, but updating graphics card drivers (so as not to use Windows’ own drivers with very poor OpenGL support) should fix it.

jon · March 16, 2021, 10:24am

I don’t believe this problem could have any impact on online studies. @darcyen I’m sure your issue is entirely unrelated

jon · March 16, 2021, 10:27am

@swann_pichon you mentioned “graphic card intel HD 520, drivers up to date” but did you install the driver from Intel or do you just mean the Windows drivers are up to date? There is a long-standing issue Microsoft often provides its own drivers but with poor OpenGL (they have a microsoft-only alternative to OpenGL called DirectX and you might think they aren’t keen to support OpenGL too heavily). Make sure you have the drivers from the card manufacturer instead

swann_pichon · March 17, 2021, 12:26pm

Dear Jon, I moved my laptop from W7 to W10 and this solved the issue. Psychopy 2021.1.2 runs fine now =) To answer your question, updating my former W7 configuration with the latest DELL driver for my DELL manufactured intel 520 graphic card had not solve the issue with Psychopy 2020.1.3. Thanks for the great work you do
