If this template helps then use it. If not then just delete and start from scratch.
OS (e.g. Win10): Win7 and MacOS 10.14.6
PsychoPy version (e.g. 1.84.x): v2021.2.3 (Win7) & v2021.2.2 (MacOS)
Standard Standalone? (y/n) If not then what?: yes
What are you trying to achieve?: Run the experiment
What did you try to make it work?: Run the experiment from the Builder/Runner. Run the compiled python script directly. Eventually commented out the offending import line, and all references to the imported variable.
What specifically went wrong when you tried that?:
Traceback (most recent call last): File "fMRI_lastrun.py", line 22, in <module> from psychopy import sound, gui, visual, core, data, event, logging, clock, colors File "/Users/jonathanshor/.psychopy3/versions/psychopy/visual/__init__.py", line 31, in <module> from psychopy.visual.backends import gamma File "/Users/jonathanshor/.psychopy3/versions/psychopy/visual/backends/gamma.py", line 20, in <module> from psychopy.tests import _vmTesting ModuleNotFoundError: No module named 'psychopy.tests'
That is the error from MacOS. The error on Win7 is essentially the same, referencing the same line in gamma.py.
The errors are not reached in identical ways, however. On Win7, the error happened when trying to run from the Builder mode. On MacOS, running from Builder mode actually works, but trying to run the compiled script from the command line produces the error above.
After doing a little digging, it seems the psychopy install referenced in the pasted error there, under .psychopy3/, is v2021.2.2 and is missing the tests subfolder, which I imagine is causing the failure. Bizarrely, the psychopy install for my python venv is v2021.2.3 and does have the tests subfolder… I’m quite confused how the Builder is finding that, but calling python from within the venv somehow finds the other install.
Regardless, the Win7 machine is my ultimate target machine. Why do some installs omit the tests folder, and should I simply copy the folder from the 2021.2.3 Mac install over to the Win7 machine?
In case it matters, the experiment was designed in the v2021.2.2 Builder, and I’m using
psychopy.useVersion('2021.2.2') in the code.
