When building with Python 3.12 and 3.13 I am unable to build with numpy support using
pip install --no-cache-dir jep. This was reported in #580. It seems pip is building in an isolated environment without numpy, even if numpy is installed which prevents setup.py from detecting numpy. I have been able to build with numpy support on all versions of Python using the--no-build-isolationso I am including that option in the command we recommend for installing jep.
