which version numpy should work?

forrest-lam commented 2 weeks ago

Same error! Have you found the compatible version of numpy?

Krankheit commented 4 days ago

This issue is probably caused by numpy versions >= 2.0.0 . pip install numpy==1.22.4 And change the 6th line of makefile to: @pip install -r requirements.txt && pip list Then BOOST_INCLUDE_DIRS=boost_path make all, it should work.
