在python中导入cython代码

Question

我有一个Cython代码“旋转多边形_网络管理系统.pyx“我试图用python代码导入它，但它给了我一个错误：

Cython代码是：

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]

旋转式gpu_nms水电站代码是：

^{pr2}$

错误是

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'

我试图使用下面的两个命令，但它也给了我一个错误。在

import pyximport 
pyximport.install()

错误：

我怎样才能解决这个问题？？ 我在Ubuntu中使用python

这是我使用的code

编辑： 我使用distutils作为@DavidW-mension，但是当我执行下面的命令时，它给了我一个错误：

setup.py build_ext --inplace
