'numpy/arrayobject.h' file not found #59

Closed joseraulgonzalez closed 6 years ago

joseraulgonzalez commented 6 years ago

I have installed both piqs and qutip via source compilation in MacOS 10.13.6. I am using Qutip 4.3.1 and piqs 1.2. If I run the following from qutip import * from qutip.piqs import * I get an error message:

fatal error: 'numpy/arrayobject.h' file not found

include "numpy/arrayobject.h"

Could someone please help me fix this?

Hi, this seems to be mostly related to incorrect numpy installation or a mismatch. Could you remove qutip, update your numpy and try again?

Alternatively, the best way to manage packages would be using anaconda. You could install Miniconda and reinstall qutip with conda install -c conda-forge qutip. This way all your packages will be kept updated and in sync. Since numpy as well as qutip rely on some C/C++ bindings, sometimes installing the incorrect binaries can lead to this type of errors.

Reinstalling did not work for me. However, a workaround that did work (a vile hack one might say) is the following: 1) cd /usr/local/include 2) ln -s /usr/local/lib/python2.7/site-packages/numpy/core/include/numpy numpy

Thanks for the help @sahmed95 ! I will close the issue now.

Great. In future, conda might be helpful. Let us know if you face any more issues.
