Error in Mac when running experiment: Failed to load component package `sound`

[hta17]

If this template helps then use it. If not then just delete and start from scratch.

macOS High Sierra (e.g. macOS):
PsychoPy version 2022.1.2
Standard Standalone? (y): StandalonePsychoPy-2022.1.2-macOS

When clicking on “Run experiment” in the builder, I get the following error message:

I’ve tried deleting any other folders with psychtoolbox in on my computer because I thought multiple directories might be confusing psychopy (giving that it’s having a problem finding the “sound” folder?). I tried the manual installation too but got lost as I am unfamiliar with python etc. I also have seen similar posts in this forum with similar errors, but I simply lack the psychopy knowledge to use them to fix my situation.

Any help whatsoever would be greatly appreciated.

Hi @hta17,

Would you mind attaching your .psyexp file here for us to take a look at?

Also, could you just confirm that you have PsychoPy added and ticked in: Security & Privacy (on your Mac) > Accessibility and also Input Monitoring?

Thanks,

Kim

Hi Kim,

Here you have a .psyexp file attached

Also, I have PsychoPy added and ticked in: Security & Privacy (on your Mac) > Accessibility, but in my Security & Privacy I have no “Input monitoring”, maybe I am missing something… (my computer
practica 1_version2.psyexp (58.3 KB)
is macOS high sierra 10.13.6)

By the way, this file runs on other non-mac computers without any problems.

Hi @hta17,

Thanks so much for this! Also thanks for clarifying that this works on non-Macs. So, Input Monitoring should be located just beneath Accessibility, as in this screenshot:

This is something that may be occurring in post-2020 Macs. If you could go to About this Mac, and on the box where you can see all of the information about your Mac (such as display, processor etc.), do you see a ‘chip’ field like this one (not necessarily with the same information in that field):

Thanks!

Hi again @hta17,

I have seen a few Mac users on the forum having a similar issue which should be fixed in the next bug release. A workaround can be found in this post. The file that is referred to in this post can be found by navigating to:

Finder > Applications > PsychoPy > Right click > Show package contents > Contents > Resources > lib > python3.8 > psychopy > sound > __init.py__

When you’ve found and opened the file (you can just open it in the Coder window of PsychoPy), just search for the following:

from .transcribe import *

It’s that line that you’ll be adding the extra lines of code around. So in the end that line will look like this:

try:
    from .transcribe import * # import transcription engine stuff
except ImportError:
    pass

Hope this helps!

Kim

Hi again Kim,

Thanks for your great instructions. Unfortunately the work around didn’t work… But I must say that now it’s not crucial that this version works on my computer as version 2021.2.3 seems to work fine, and I’m only running a simple behavioural experiment.

Anyways, the mac I’m working on is very old (late 2011), so maybe that’s why there’s no input monitoring option?

Regards,
