NumPy

I have a problem related to NumPy that I get when I compile the code:

root@ares:/home/# make -j20

NumPy is installed on my machine:

root@ares:/home/#python -m pip install numpy
Requirement already satisfied: numpy in /usr/local/lib/python3.6/dist-packages (1.19.5)

The problem is the macro NUMPY_IMPORT_ARRAY_RETVAL that is not defined. Apparently, this macro is defined as NULL for python version >=3, and nothing otherwise. Strangely, even if I have Python 3.6 installed in Ubuntu, this macro is not defined. For the moment, I have replaced NUMPY_IMPORT_ARRAY_RETVAL with NULL in python_module.cpp.

Thank you, fix committed!
