pyopencl in python 3.11 crashes at initialization

[lpagani91]

pyopencl only exists for python 3.10 and 3.11. After installing python3.11 and launching ipython-3.11, i get this :

In [1]: import pyopencl

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.4.6 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

The above exception was the direct cause of the following exception:

numpy-3.11 version is

The following ports are currently installed:
  py311-numpy @2.4.6_0+gfortran+openblas (active)

this is somewhat similar to my previous ticket #69350 on the subject.

I am still having the same problem in 2026 as what I mentioned in #69350...

I am now running with Macports 2.12.5 environment, made a fresh reinstall of all my ports. Since pyopencl crashes at start in python3.11 and is not available for python3.14 inside Macports, I collected it using PIP-3.14 :

laurent>sudo -H pip-3.14 install pyopencl

I tested that i could import pyopencl in python3.14

LOC_OL>python3.14

>>> import pyopencl
>>>

however, trying to run the test.py mentioned in ​https://trac.macports.org/ticket/69350#comment:1 still crashes :

However, since this is not directly linked to Macports anymore, you might consider it is none of your business... Fair enough. Simply, I wonder whether a true Macports install of pyopencl in Python 3.14 would help ?
