Your system is ready to brew.

Verification

• My "brew doctor output" says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I tried to diagonalize a small matrix using scipy.
So I ran the command

python3.12 -c "from scipy import linalg;linalg.eigh([[1]])"

What happened (include all command output)?

It outputs

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/homebrew/lib/python3.12/site-packages/scipy/_lib/deprecation.py", line 213, in inner_f

What did you expect to happen?

When I install scipy with pip I do get an error.

When running python3.12 -c "from scipy import linalg;print(linalg.eigh([[1]]))" I get
(array([1.]), array([[1.]]))
as expected.

Step-by-step reproduction instructions (by running brew commands)

brew install scipy
python3.12 -c "from scipy import linalg;linalg.eigh([[1]])"

Looks like an upstream issue: scipy/scipy#19831

v1.13.0 was just released upstream (not yet in brew) which may provide a fix https://github.com/scipy/scipy/releases/tag/v1.13.0 / #167846
