Always getting lock error no matter which show I use

>>> plt.show("block")

Funny I was just looking up because of the exact same issue. Python 3.11, matplotlib 3.8.4 The exact cause of the error is: AttributeError: 'MyRenderer' object has no attribute 'lock' Very cool project, thanks.

Same.

Has anyone found a solution?

I found a workaround: use an older version of matplotlib (3.5.3 works in my case)
