为 Cython 设置 PyCharm

Setup of PyCharm for Cython(为 Cython 设置 PyCharm)

问题描述

我看到 PyCharm 支持 Cython.

我总是可以在终端中编译和运行，但我想知道在 PyCharm 中是否有办法做到这一点.在链接中它说:编译是使用外部工具完成的.首选的构建系统(Makefile、setup.py 等)应该配置为外部工具."我想知道如何进行此配置.非常感谢 PyCharm 中使用 Cython 的 Hello World 小示例.

I could always compile and run in terminal, but I'm wondering if there is a way to do this in PyCharm. In the link it says: "Compilation is done using external tools. The preferred build systems (Makefile, setup.py, etc.) should be configured as external tools." I'm wondering how to do this configuration. A small Hello World example in PyCharm using Cython would be much appreciated.

谢谢

推荐答案

在这里回答我自己的问题:

Answering my own question here:

假设我们有函数fib.pyx:

def fib(n):
"""Print the Fibonacci series up to n."""
a, b = 0, 1
while b < n:
    print b,
    a, b = b, a + b

有两种编译和运行的方法

There are two ways to compile and run this

1. 使用安装文件.制作文件 setup.py:

from distutils.core import setup
from Cython.Build import cythonize

ext_options = {"compiler_directives": {"profile": True}, "annotate": True}
setup(
    ext_modules = cythonize("fib.pyx", **ext_options)
)

ext_options 包含在此处以生成带有注释的 html 文件.要运行此文件，您必须转到 Tools --> Run setup.py Task.然后输入 build_ext 作为 task name，并在提示输入 Command Line 时输入 --inplace.生成文件fib.c、fib.o和可执行文件fib.so.注释文件 fib.html 也被创建.

The ext_options is included here to generate the html file with annotations. To run this file you have to go to Tools --> Run setup.py Task. Then type in build_ext as task name and when prompted for Command Line input type --inplace. The files fib.c, fib.o and the executable file fib.so is generated. The annotation file fib.html is also created.

现在，以下代码应该可以在任何 python 文件中使用，例如 main.py:

Now, the following code should work in any python file, for example main.py:

import fib
fib.fib(2000)

import pyximport; pyximport.install()
import fib
fib.fib(2000)

import pyximport; pyximport.install()
import subprocess
subprocess.call(["cython", "-a", "fib.pyx"])
import fib
fib.fib(2000)
