numpy 2.0

[bmiszalski]

I ran a pip install today of the pipeline and it grabbed numpy 2.0 as part of the requirements for the installation as listed in setup.py.

Trying to run the pipeline resulted in the following exception being raised:

File "/home/dcadmin/.local/lib/python3.11/site-packages/pywifes/wifes_calib.py", line 571, in derive_wifes_calibration temp_fvals = savitzky_golay(temp_full_y,101,1,0) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/dcadmin/.local/lib/python3.11/site-packages/pywifes/wifes_calib.py", line 394, in savitzky_golay b = numpy.mat([[k**i for i in order_range] for k in range(-half_window, half_window+1)]) ^^^^^^^^^ File "/usr/local/lib/python3.11/dist-packages/numpy/init.py", line 397, in getattr raise AttributeError( AttributeError: np.mat was removed in the NumPy 2.0 release. Use np.asmatrix instead.

There may be other incompatible functions than the example given above, but I haven't tried to take this any further to find them.

It would be a good idea to update the numpy functions to be 2.0 compatible.

Otherwise a temporary fix could be specifying in setup.py: "numpy < 2.0",

That's a good idea to resolve any numpy conflicts. In this particular case, it would be worth considering replacement of the hand-crafted S-G filtering with the more feature-rich scipy version. (I suspect it was added manually because the S-G filter didn't exist in scipy when pywifes was first written.)

[felipeji]

We have a similar issue with scipy, so in the setup.py is set as scipy==1.9.1. As numpy 2 is not compatible with scipy 1.9.1, setting the pipeline properly to work with numpy 2 would means that scipy incompatibilities need to be fixed as well. So for now, I just set numpy < 2.0 in the setup.py. I'll leave the issue open, including a note in the section Known Issues and Suggestions for Improvement in the readme for future improvement.

I also had to set scipy >= 1.9.1 and photutils>=1.8.0 to get it to build properly on debian:12. I'll try and reproduce the error I get - essentially just build requirements for scipy conflicting with other things.

note: This error originates from a subprocess, and is likely not a problem with pip. error: subprocess-exited-with-error `

Anyhow, adding continuous testing / integration will help sort out these packaging problems (for different dependencies and different versions of Python)

[felipeji]

Yeah, in the last version (the one we deliver) we have in the setup.py:

    install_requires=[
        "wheel",
        "setuptools",
        "astropy",
        "scipy==1.9.1",
        "numpy",
        "matplotlib",
        "photutils==1.8.0",
        "pandas",
]

I'm now added the condition in numpy <2

[bmiszalski]

Right, specifically I need to have >= for scipy (and probably photutils). The equality alone was not sufficient.
