This is showing up in SymPy's CI but only for Python 3.11.

The problem is caused by the release of numpy 1.26.0 two days ago.

Downgrading numpy fixes the problem:

$ pip install 'numpy<1.26'
...
Successfully installed numpy-1.25.2
$ python -c 'import aesara'

Thanks!

Thanks!

Any time. I'll create a new release once #1509 is done.
