Psychopy 2021.2.0 crashing Python on experiment start

Builder
1

OS: Mac OS X 10.15.7 (19H15)
PsychoPy version: 2021.2.0
Standard Standalone? (y/n): standalone
What are you trying to achieve?: run experiment

Before today I was running psychopy 2020.1.2 just fine, however I wanted to upgrade to 2021.2.0 in order to use the new microphone recording features. Now, I can’t start any experiment locally - it crashes Python on experiment start. This happens both for an already-developed experiment, and a brand new one with just one routine added with a textbox. There’s no error in the psychopy output, but I get a system problem report (see below). Is this a psychopy issue or a me issue? I’ve already tried removing and re-adding input monitoring permissions and deleting the app and user preference config files just to see if it was a problem with those, but that didn’t help.

I’m having the same issue as well.
Tried to run a test trial with text presentation and the program crashes at the start.
(Using Standalone)

3

On of my undergraduates is reporting this same error. Seems to be some issues with the latest version of psychopy and mac OS X. I’m having them role back to [2021.1.4] to see if that helps for now.

4

At least in my case the fault is with the keyboard handling, for example

kb = keyboard.Keyboard()

crashes Psychopy. This is from the Coder’s Demos->input->keyNameFinder.py
Whereas demos that display visual stimuli but do not poll the keyboard work.

This is on macOS BigSur Macbook Pro (2016) and also on BigSur 11.4 M1 MacBook Pro (2020).

5

I have the exact same problem.
Running macOS Big Sur version 11.4 on a MacBook Air (2020).
Also tried to role back to [2021.1.4] but this sadly did not help.

6

I’m also having this problem! I’m very new to using PsychoPy so I wasn’t sure that I had done everything correctly. But it’s encouraging (?) to see that others are having the same system error that I’m having. Hopefully it’s fixed soon.

7

Rooslucas,
Does the following still not work for you even on 2021.1.4?

8

I’m guessing that the reason for the error is the following change noted in the Changelog:

  • Py: hardware.Keyboard class now supports ioHub as a backend and will use that in preference to Psychtoolbox keyboard (PsychHID) if ioHub has been started before the Keyboard is created. ioHub keyboard is similarly in performance but with fewer constraints (can handle a wider range of keyboards)

Unfortunately there seems to be no way to go back to Psychtoolbox keyboard without changing the source code (psychopy.hardware.keyboard — PsychoPy v2021.2)
@Becca

9

By editing the source code, I switched the keyboard from ioHub back to ‘ptb’ but that doesn’t fix the problem.
On my machine, the failure occurs at the following line of keyboard.py (around line 188):

buffer = _keyBuffers.getBuffer(devId, bufferSize)

However the code around there looks identical to that of Psychopy2021.1.4, especially in the context of Keyboard.backend = 'ptb' which I’ve now set, so I don’t know what the problem is.

10

Just here to say, I’m having the same issue!

11

fwiw, rolling back to 2021.1.4 did not work for me. I had to go back to a 2020 version entirely.

12

Hi There,
Thanks for flagging.
This is an issue the team were aware of, sorry it is affecting so many of you here! I need to check in on the status/progress - but watch this space and we will get back to you when we have an update!

For me [2021.1.4] does work now. I had to change something in my settings: System Preferences > Security & Privacy > Input Monitoring and allow PsychoPy3. (Name error: name 'event' is not defined)

So rolling back to the earlier version does help for now.

I have the same problem as smburns47. My Builder scrips that run just fine on 2021.1.4 (standalone) will not run on 2021.2.0 (standalone). I get the same error message as smburns47 reports. Even a bare-bones experiment (default with a default text component) crashes. Everything works if I reinstall 2021.1.4.
MacOS 11.4 (Big Sur),MacBook Pro (16-inch, 2019)

Hey there,

i am having the same problem as all of you above have reported (PsychoPy V2021.2.0 on WIN 10). My problem is, that going back to PsychoPy Version 2021.1.4 or older versoins doesn’t work either! At the moment, I am completely stuck and can’t go on with my work at all.

Has any solution or recommendation already been found?

Best,
Lea

Hi There,

The team have managed to put a fix in place for mac and that should be released in the next few days here Releases · psychopy/psychopy · GitHub - this is however the first time we are hearing of the issue on windows 10 - does that still happen if you completely install 2021.1.4 as a standalone version?

Hello Becca,

I have uninstalled 2021.2.0 manually and installed 2021.1.4 as a standalone version, and now it works! Only installing 2021.1.4 and by doing that automatically deinstalling 2021.2.0 did not work, as it seems as if windows doesn’t really uninstall the program (although it is supposed to do so).

Thank you!
Lea

Hello,
I’m running window 10 and have the same problem. My experiment worked fine in v2021.1 but I updated to v2021.2 and the builder opens up with missing routines and the experiment doesnt run.

@Lealexandra What do you mean exactly by manually deinstalling or installing? can you specify the steps you took to make your experiment run again with v2021.1?

thankuuu!

20

That fixed it! For example, the keyNameFinder.py demo in Coder->Demos->Input now works!

Hello all! I just wanted to say that I’m having this issue with 2022.1.2 on Mac iOS Monterrey.

I tried running an old experiment that a lab member made with her laptop on an older version of Psychopy, and it didn’t work. Then, I made the simplest experiment (just a Welcome page), and it still quits when I run it.

Any advice would be much appreciated.
