ImportError: No module named numpy.core._multiarray_umath on mac os 10.12

[copilco]

Hello

I managed to compile the code after some effort with macports. Now it compiles but when i run it shows an error with the numpy library.

As i have several python and numpy version installed i have created a conda enviroment to use python 2.7 with numpy 4.8.0

But the error keep showing when i run the code

numpy 4.8 ? The latest version is 1.17 ...

Anyways, this is an issue of versions of numpy vs other packages in your python installation. It has little to do with smilei. See for instance numpy/numpy#11871. Try to upgrade numpy : pip install --upgrade numpy

Fixed with pip install --upgrade numpy
