Installation error

[tjtakys]

Hi to everybody,

I failed several times in installing pyradex. My PC is a Ubuntu 22.04.3 LTS and the software versions are as follows.
~/software/pyradex$ python -c "import sys, astropy, numpy; print(sys.version); print(numpy.__version__,astropy.__version__)" 3.10.12 | packaged by conda-forge | (main, Jun 23 2023, 22:40:32) [GCC 12.3.0] 1.26.0 5.3.4

After having installed astroquery and specutils, I cloned pyradex from the repository.
Then I run "python setup.py install_radex install", but the installation is interrupted by this message:

I can make radex as normal following the official radex homepage, so I suspect that the problem is associated with f2py.
What can I do? Thank you for your help!

I agree @aopikumin , f2py is almost certainly playing a role here. Can you report what numpy version you're using?

I am not sure I'll be able to debug this any time soon.

[tjtakys]

Thank you for your quick reply! I use numpy v1.26.0.

I don't get this issue with numpy 1.23.5 on my redhat system or with 1.26.2 on my mac, both using python 3.10. This isn't super helpful, but at least it rules out some easy explanations.
