旋转错误：失败，退出状态为 2。麻木和皮维斯塔

Question

我想对以下代码进行西顿化，但我收到一个错误。

import numpy as np

cimport numpy as np

import pyvista as pv

from mesh_funcs import *

cimport cython 

from libcpp cimport bool

#import matplotlib.pyplot as plt

#Getting mesh points from pyvista unfortunately with a for loop

cdef class pv_cell:

    def pv_grid_cell_data(mesh2,bool points_toggle=True,

                          bool centres_toggle=True,bool volumes_toggle=True, bool areas_toggle=True):

        if areas_toggle==True:

            points_toggle==True

        if centres_toggle==True:

            points_toggle==True

        cdef np.ndarray gcp=np.zeros([mesh2.n_cells,8,3])

        cdef np.ndarray gcc=np.zeros([mesh2.n_cells,3])

        cdef np.ndarray gcv=np.zeros([mesh2.n_cells,3])

        cdef np.ndarray grid_facets=np.array([[0,1,2,3], [0,1,5,4], [1,2,6,5], [7,6,2,3], [7,3,0,4], [4,5,6,7]])

        cdef np.ndarray gca=np.zeros([mesh2.n_cells,6])

        for n1 in range(0,mesh2.n_cells):

            if points_toggle==True:

                gcp[n1]=mesh2.extract_cells(n1).points

            if centres_toggle==True:

                gcc[n1]=[np.mean(gcp[n1][:,0]),np.mean(gcp[n1][:,1]),np.mean(gcp[n1][:,2])]

            if volumes_toggle==True:

                gcv[n1]=mesh2.extract_cells(n1).compute_cell_sizes()["Volume"]

            if areas_toggle==True:

                for n2 in range(0,6):

                    ph8=gcp[n1][grid_facets[n2]]

                    gca[n1,n2]=tri_area(ph8[[0,2,3]])+tri_area(ph8[[0,1,3]])

        return gcp,gcc,gcv,gca

我的 setup.py 如下

from setuptools import setup

from Cython.Build import cythonize

import numpy

setup(

    ext_modules=cythonize("pv_cell_funcs.pyx"),include_dirs=[numpy.get_include()])

我通过以下方式启动 setup.py。

python setup.py build_ext --inplace

pause

错误很长。它声明 bool 是一个未声明的标识符。然后它列出了许多语法错误。最后一行是

error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\...x64\\cl.exe' failed with exit status 2

由于您正在运行：from libcpp cimport bool您应该将语言从默认语言更改为：cc++setup.pyfrom setuptools import setupfrom Cython.Build import cythonizeimport numpysetup(    ext_modules=cythonize("pv_cell_funcs.pyx", language='c++'),    include_dirs=[numpy.get_include()])请参阅如何声明 bool 类型的对象？以便在 cython 中使用。bool
