Hello Thomas,
you need to downgrade numpy to a version < 2.0, the pip installation is broken at the moment.
Essentially, try using the commands mentioned in [1].
Best regards, r.

Hello,
I'm writing to you because I experience some difficulties to install properly sfepy ... First, I use Anaconda and I am in a windows environment. I created a new environment to do the install with Python 3.12.4 in it. When I tried to install sfepy through conda install -c conda-forge sfepy commands it didn't go through. Instead, I used pip install which finished properly. I also installed pytest with pip install pytest but when I run sfepy-test I have several errors. I can't find site_cfg.py files to edit it, as required in the debugging section. So I can only copy paste what the output of the sfepy-test command is (see below the email).
Could you help me ?
Regards,
Thomas Carlioz
