How to create a .pyd file?

Question

I am creating a project that uses Python OpenCV. My image processing is a bit slow, so I thought I could make the code faster by creating a .pyd file (I read it somewhere).

I can create a .c file using Cython, but how do .pyd make a .pyd ? Although they are a kind of .dll , should I make the .dll first and convert it? And I think they are not platform independent, what are the Unix equivalents?

Thanks for any help!

You need to run the setup.py in the terminal. This 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) 

In the terminal (cmd on Windows) you need to execute the command

 python setup.py build_ext --inplace 

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