How are characters contained in libpythonX.X related to numpy extension dynamic libraries?

Question

I am currently having a problem where I can use and import numpyin an interpreter environment, but I cannot import or use numpyfrom Python built into C/C++. So I'm curious how much numpyextension libraries, in particular,

numpy/core/multiarray.cpython-35m-x86_64-linux-gnu.so

associated with standard Python package characters (per PyExc_UserWarningcharacter PyExc_UserWarning). My current error output says that PyExc_UserWarning is undefined. This symbol exists in libpythonX.Ymsoas I confirmed using the command nm. I ran

ldd multiarray.cpython-35m-x86_64-linux-gnu.so

and got the following output:

, , . numpy multiarray.cpython-35m-x86_64-linux-gnu.so , multiarray ?

, . , !
