我有一个运行速度太慢的巨大 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,然后遇到了 Cython。有人建议我将我的 Python 代码保存为 .pyx 并创建一个 setup.py 文件,该文件将“细胞化”我的代码,然后将其编译成 C。
但是,当我键入时出现错误C:/Users/loic/Documents/maido-cython/setup.py build_ext –inplace
:
Compiling C:/Users/loic/Documents/maido-cython/maido-cython.pyx because it changed.

这里是我使用的代码 ( maido-cython.py
) 和 4 个 numpy 文件 ( ******_maido_856x512.npy
)(不用担心我将它上传到我自己的 Google 帐户):https ://drive.google.com/drive/folders/0B7P95aWmH4DUek9xcEROb0FQR0E
这是我在设置文件中写的:
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"),
)
有人可以告诉我我做错了什么吗?
编辑:
我听取了您的建议并更改了文件。我还更改了上传的链接:https ://drive.google.com/drive/folders/0B7P95aWmH4DUcFY0X3JycGlacDQ
当我键入C:/Users/loic/Documents/maido/setup.py build_ext –inplace
与冒号字符“:”有关时,我遇到了另一个问题

我没有找到对应的unicode字符。我应该添加什么?
