Cython文件无法编译

Question

我有一个运行得太慢的巨大Python代码。我不想用C重写我的整个代码，所以我做了一些研究，并且遇到了Cython。我被告知我的Python代码保存为.pyx并创建一个setup.py文件，将“cytonize”我的代码，然后将其编译成C.

然而，当我键入C:/Users/loic/Documents/maido-cython/setup.py build_ext –inplace我得到一个错误：

Compiling C:/Users/loic/Documents/maido-cython/maido-cython.pyx because it changed.

    raise CompileError(None, pyx_file) 
Cython.Compiler.Errors.CompileError: C:/Users/loic/Documents/maido-cython/maido-cython.pyx 

下面的代码（maido-cython.py）和我用（不要担心，我上传它在我自己的谷歌账户）的4个numpy的文件（******_maido_856x512.npy）：https://drive.google.com/drive/folders/0B7P95aWmH4DUek9xcEROb0FQR0E

以下是我在我的设置文件中写道： ：

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

from Cython.Build import cythonize 

setup(name = "graphique", 
     ext_modules = cythonize("C:/Users/loic/Documents/maido-cython/maido-cython.pyx"), 
    ) 

有人能告诉我我做错了吗？

编辑：

我把你的意见和更改的文件。我也改变了上传的链接：我还有一个问题https://drive.google.com/drive/folders/0B7P95aWmH4DUcFY0X3JycGlacDQ

当我输入C:/Users/loic/Documents/maido/setup.py build_ext –inplace具有与冒号做“：”

我没有找到对应的Unicode字符。我应该添加什么？

Answer 1

您可以完美执行一个.py*文件，其基数名称如a-b但您不能导入它。

import a-b 

无效，因为a-b不是有效蟒标识符（解释为“负B”）。您的cythonize过程也一样，并且消息足够清晰。

修复：将maido-cython.pyx重命名为有效的python名称，例如maido_cython.pyx。

编辑：你的另一个问题，它的另一个经典的问题：

path = "C:\Users\loic\Documents\maido" 

\U被解释为Unicode转义。使用像这样的原始前缀：

path = r"C:\Users\loic\Documents\maido"
