致命错误:numpy/arrayobject.h:没有这样的文件或目录

2022-01-23 00:00:00 python numpy g++ c++

我可以分享的内容有限，因为这是我从 Ubuntu 14.04 移植到 16.04 的大量代码的一部分.

I am limited on what I can share as this is part of a huge stack of code that I am porting from Ubuntu 14.04 to 16.04.

这应该是微不足道的，但不知何故我正在为此苦苦挣扎.它没有找到我在源文件中使用 #include <numpy/arrayobject.h>

It should be trivial, but somehow I am struggling with this. It doesn't find numpy/arrayobject.h that I am referencing in my source file with #include <numpy/arrayobject.h>

我会尽可能多地分享，看看是否有人可以指导我解决问题.

I will try to share as much as I can, see if someone can guide me through a resolution.

蟒蛇

$ python --version
Python 2.7.12

一些环境变量

PYTHON       /usr/bin/python2.7
ARCH         x86_64
OS           Linux
VERSION      4.4.071generic

ODIR         build.x86_64-linux2-gcc
STATICLIBDIR build-static.x86_64-linux2

错误

make 命令导致

+++ Compile mycore/boost_numpy.cc to build.x86_64-linux2-gcc
anycore/boost_numpy.cc:2:31: fatal error: numpy/arrayobject.h: No such file or directory

我的源文件

user@deploy:~/my-linux$ vim mycore/boost_numpy.cc

#include "anycore/boost_python_headers.h"
#include <numpy/arrayobject.h>           <====== DECLARATION
#include <numpy/ufuncobject.h>        
#include "mycore/boost_numpy.h"
#include "mycore/numerical.h"
#include "mycore/vec3.h"

using namespace boost::python;

PyObject *
read_numeric_file_ficii(FILE *fp, int ncols, char arrtype, int headlines, int taillines)
{
  if (!(arrtype=='d' || arrtype=='f' || arrtype=='i')) {
    PyErr_SetString(PyExc_ValueError, "Unknown array type for read_numeric_file");
    return NULL;
  }
...FILTERED...

声明文件numpy/arrayobject.h在磁盘上

root@deploy:/home#  find / -name arrayobject.h
/usr/local/lib/python2.7/dist-packages/numpy/core/include/numpy/arrayobject.h

请告诉我如何改进这个问题.方向或指针是最受欢迎的

Please let me know how I can improve the question. Directions or pointers are most welcome

$ ls -l /usr/include/numpy
ls: cannot access '/usr/include/numpy': No such file or directory

已解决

sudo ln -s  /usr/local/lib/python2.7/dist-packages/numpy/core/include/numpy /usr/include/numpy

推荐答案

我在部分损坏的 Debian 安装中遇到了同样的行为.

I have experienced the same behavior on a partly broken Debian installation.

我通过重新建立符号链接修复了错误

I fixed the error by reestablishing a symbolic link

sudo ln -s/usr/lib/python2.7/dist-packages/numpy/core/include/numpy/usr/include/numpy
