如何创建.pyd文件？

问题描述

我正在创建一个使用Python OpenCV的项目。我的图像处理有点慢，所以我想我可以通过创建一个 .pyd 文件（我在某处读到）更快的代码。

I'm creating a project that uses Python OpenCV. My image processing is a bit slow, so I thought I can made the code faster by creating a .pyd file (I read that somewhere).

我可以使用Cython创建一个 .c 文件，但是如何使 .pyd ？虽然他们是一种 .dll ，我应该先做一个 .dll 并转换吗？

I am able to create a .c file using Cython, but how to make a .pyd? While they are a kind of .dll, should I make a .dll first and convert it? And I think they're not platform-independent, what are equivalents on Unix?

感谢任何帮助！

推荐答案

您必须在终端中运行 setup.py 文件。这个例子使用 numpy

You have to run a setup.py file in a terminal. This one is an example that uses numpy

try:
    from setuptools import setup
    from setuptools import Extension
except ImportError:
    from distutils.core import setup
    from distutils.extension import Extension

from Cython.Distutils import build_ext
import numpy as np

ext_modules = [Extension("my_code_cython",["my_code_cython.pyx"]),
               Extension("another_code_cython",["another_code_cython.pyx"])]

setup(
    name= 'Generic model class',
    cmdclass = {'build_ext': build_ext},
    include_dirs = [np.get_include()],
    ext_modules = ext_modules)

Windows）你必须执行命令

In the terminal (cmd in Windows) you have to execute the command

python setup.py build_ext --inplace

重要的是，我想你已经安装了编译器（例如微软的Visual C ++编译器包为Python 2.7）。您可以在 https://github.com/cython/cython/wiki/CythonExtensionsOnWindows

It is important that I suppose you have installed the compiler (Microsoft Visual C++ Compiler Package for Python 2.7 for example). You can find more information in https://github.com/cython/cython/wiki/CythonExtensionsOnWindows
