Импортировать код Cython в Python

У меня есть код Cython "rotate_polygon_nms.pyx", и я попытался импортировать его в код Python, но он выдает ошибку:

Код Cython:

import numpy as np
cimport numpy as np

assert sizeof(int) == sizeof(np.int32_t)

cdef extern from "rotate_gpu_nms.hpp":
    void _rotate_nms(np.int32_t*, int*, np.float32_t*, int, int, float, int)

def rotate_gpu_nms(np.ndarray[np.float32_t, ndim=2] dets, np.float_t thresh, np.int32_t device_id=0):
    cdef int boxes_num = dets.shape[0]
    cdef int boxes_dim = dets.shape[1]
    cdef int num_out
    cdef np.ndarray[np.int32_t, ndim=1] \
        keep = np.zeros(boxes_num, dtype=np.int32)
    cdef np.ndarray[np.float32_t, ndim=1] \
        scores = dets[:, 5]
    cdef np.ndarray[np.int_t, ndim=1] \
        order = scores.argsort()[::-1]
    cdef np.ndarray[np.float32_t, ndim=2] \
        sorted_dets = dets[order, :]
    thresh = <np.float>thresh
    _rotate_nms(&keep[0], &num_out, &sorted_dets[0, 0], boxes_num, boxes_dim, thresh, device_id)
    keep = keep[:num_out]
    return order[keep]

Код rotate_gpu_nms.hpp:

void _rotate_nms(int* keep_out, int* num_out, const float* boxes_host, int boxes_num,
          int boxes_dim, float nms_overlap_thresh, int device_id);

Ошибка

Traceback (most recent call last): File "inference1.py", line 17, in from libs.fast_rcnn import build_fast_rcnn1 File "../libs/fast_rcnn/build_fast_rcnn1.py", line 14, in from libs.box_utils import nms_rotate File "../libs/box_utils/nms_rotate.py", line 13, in from libs.box_utils.rotate_polygon_nms import rotate_gpu_nms ImportError: No module named 'libs.box_utils.rotate_polygon_nms'

Я попытался использовать две приведенные ниже команды, но тоже выдает ошибку.

import pyximport 
pyximport.install()

Как я могу решить эту проблему?? Я использую python в Ubuntu

Это тот код, который я использовал

Обновлено:: Я использовал distutils как значение @DavidW, но когда я выполнил приведенную ниже команду, у меня возникла ошибка:

setup.py build_ext --inplace
