BUG: Numpy New Release incompatible with Pytensor blas_headers

[carlosagostini]

Describe the issue:

Two days ago Numpy released a new version 1.26.0 documentation here.

The new version doesn't have anymore the attribute get_info(), which is used in the file cmodule.py (link here) on the line 2720.

Consequently, if a user tries to import pymc with Numpy > 1.25.0, he will get an error, given that these modules are used on the package.

Reproducable code example:

%pip install pytensor
%pip install numpy==1.26.0
from pytensor.tensor.blas_headers import blas_header_text, blas_header_version

import numpy as np
np.__config__.get_info("blas_opt")

Error message:
