issues plotting 3d room..

[rorywalsh]

I'm having issues plotting a 3D room? Here is my simple script:

import numpy as np
import matplotlib.pyplot as plt
import pyroomacoustics as pra

corners = np.array([[0,0], [0,3], [5,3], [5,1], [3,1], [3,0]]).T  # [x,y]
room = pra.Room.from_corners(corners)
room.extrude(2.)

fig, ax = room.plot()
plt.show()

and the output:

λ python3 test2.py 
Traceback (most recent call last):
  File "test2.py", line 9, in <module>
    fig, ax = room.plot()
  File "C:\Python36\lib\site-packages\pyroomacoustics\room.py", line 1657, in plot
    ax = a3.Axes3D(fig, auto_add_to_figure=False)
  File "C:\Python36\lib\site-packages\mpl_toolkits\mplot3d\axes3d.py", line 106, in __init__
    fig, rect, frameon=True, box_aspect=box_aspect, *args, **kwargs
  File "C:\Python36\lib\site-packages\matplotlib\axes\_base.py", line 525, in __init__
    self.update(kwargs)
  File "C:\Python36\lib\site-packages\matplotlib\artist.py", line 996, in update
    raise AttributeError(f"{type(self).__name__!r} object "
AttributeError: 'Axes3D' object has no property 'auto_add_to_figure'

any ideas?

Ok, I managed to get this running on my laptop. I still can't get it to run on my desktop, with similar tools installed, so any help would be much appreciated.

Hi bro, I have exactly the same problem as u did. I suspect that it's because of the wrong version of matplotlib. Could u tell me which version is it on your laptop that can work? Maybe I'll try it.

Sure, I have 3.7.0. Can you let me know if that does the trick?

I also suspect the python version may be the problem. It looks like you have 3.6 on your desktop. Python 3.6 has reached end of life and is not officially supported (in general, and by pyroomacoustics too). It is possible that matplotlib itself does not support 3.6.

Thank u so much! u r right, it's working well with python 3.9 and matplotlib 3.7.0

Great, I'll update accordingly on my desktop machines 👍
