Got " ValueError: setting an array element with a sequence"

[jensen201113]

hi,
I tried to make sms_wsj and got " ValueError: setting an array element with a sequence" error.
It seems that the shape of the audio from WSJ and that from rirs are incompatible, which are of
1 channel and 6 channel respectively. I don't know how to fix it. Please help, thank you.

Some terminal outputs are as following:

Edit from boeddeker: use code block for terminal output

hi jensen201113,

this is an issue, with numpy 1.24 or higher.
A quick fix would be to install an older numpy version.

The following works in numpy 1.23, while it fails in 1.24

import numpy as np
np.array([[1, 2], [3, 4, 5]])
