I have a directory structure as so: /my_module init.py A/ __init__.py a.pyx B/ __init__.py b.pyx In b.pyx I want to cimport functions from A.a. A regular python import

Solution 1:

You have to create a cython declaration file, a .pxd

It shall contain only declarations of classes and functions that you want to import.
