AttributeError: 'Arrow3D' object has no attribute 'do_3d_projection' when running example.py

[dave-schaefer]

Hello,
when running the example.py with the current stable matplotlib==3.5.2, I get this error: AttributeError: 'Arrow3D' object has no attribute 'do_3d_projection',

It works with matplotlib==3.4 though.

Results when running "python3 example.py":

Hi, @dave-schaefer
Please use matplotlib v3.4.3 for now. And maybe you can check this discussion:matplotlib/matplotlib#21688

Best Regards

Hi, @dave-schaefer
After v2.0.0 update, you can use matplotlib >= v3.5.2 now !

Best Regards
