RadialStim not functioning on any versions from v2024.1.2 onward

Coding

From v2024.1.2 onward, I get this error when trying to use visual.RadialStim

    stimulus1 = visual.RadialStim(
  File "/Applications/PsychoPy.app/Contents/Resources/lib/python3.8/psychopy/contrib/lazy_import.py", line 118, in __call__
    return obj(*args, **kwargs)
TypeError: RadialStim() takes no arguments

No issues prior to 2024.1.2. I tested all the other 2024 versions and some 2023 versions.

OS: MacOS 15
Psychopy Version: 2024.1.2 onward
Plugins: Psychopy-visionscience 0.0.7 is installed via plugin manager.

Here’s code I used:

from psychopy import visual, core, event

# Create a window
win = visual.Window(monitor='my_monitor', size=[2560,1440], fullscr=True, screen=0)

# Create stimulus
stimulus1 = visual.RadialStim(
win = win,
units='deg',
colorSpace='rgb',
size=20,
texRes = 512,
angularRes = 512,
tex="sqrXsqr",
color = 1,
contrast = 1,
pos = (0,0),
visibleWedge= (0,360),
mask = 'circle',
radialCycles = 2.5, # 5 rings
angularCycles= 10, # 20 slices
radialPhase = 0,
angularPhase = 0,
)

stimulus1.draw()
win.flip()
core.wait(3)
win.close()
core.quit()

thanks!

Same goes for NoiseStim.

Hi @mpinsk,

Could you try adding the following to the top of your script:

from psychopy import plugins
plugins.activatePlugins()

Thanks,

That worked! Any chance you can explain why I need that now and not in earlier versions? Just curious.

Thank you!!

Plugins were introduced in 2023 to reduce the size of the core package.

I met the same problem but failed to solve it as you suggested.

Here I tried the same code, with the two lines on the top, but it did not work. :frowning: PychoPy 2024.2.4 compatiblity+)

Thank you !

Here is the error information：

stimulus1 = visual.RadialStim(

stimulus1.draw()

Thank you !

Hi @Meng,

Could you please try saving your script somewhere other than in PsychoPy’s Lib folder, for instance on your Desktop or in your Documents folder and see if it runs successfully then?

Thanks so much,

Kim
