Cython: как я могу импортировать несколько классов или объектов из одного файла .pyx ⇐ C++

[Anonymous]

Для простоты я дам вам, ребята, мой .pyx.
У меня есть файл Geometry.pyx, и в этом файле есть классы Segment, Angle и Circle.
cimport Geometry

# Define Python classes
cdef class Segment:
def __cinit__(self, float length):
self.c_segment = make_shared[_Segment](length)

def get_length(self) -> float:
return self.c_segment.get().get_length()

cdef class Angle:

def __cinit__(self, float degrees):
self.c_angle = make_shared[_Angle](degrees)

def get_degrees(self) -> float:
return self.c_angle.get().get_degrees()

def get_radians(self) -> float:
return self.c_angle.get().get_radians()

cdef class Circle:

def __cinit__(self, float radius):
self.c_circle = make_shared[_Circle](radius)

def get_radius(self) -> float:
return self.c_circle.get().get_radius()

def get_diameter(self) -> float:
return self.c_circle.get().get_diameter()

def get_area(self) -> float:
return self.c_circle.get().get_area()

def get_perimeter(self) -> float:
return self.c_circle.get().get_perimeter()

Как мне написать файл setup.py?
Я написал, как показано ниже, но получил ошибку
from setuptools import setup, Extension, find_packages
from Cython.Build import cythonize

# "Geometry.Geometry",

# )

include_path=["src/Geometry"],
annotate=True
)+
cythonize(extension_circle,
compiler_directives={'language_level': 3},
include_path=["src/Geometry"],

)

Test.py
from Geometry import Segment, Angle, Circle

class TestGeometry:
def test_segment_length(self):
seg = Segment(10.0)
# assert seg.get_length() == 5.0
print("HELO")
