ImportError about 'lrec.utils.data_utils.data_cython_helpers'（jupyter notebook python匯入不了C檔案）__python

1.剛開始不會用才導致.

2.首先瞭解一下基本知識。要寫 either make a setup.py for the module, as described at this page, or use pyximport to automatically compile and build your module with just an import.我選第一個。

set.py如下詳解解釋參考

#!/usr/bin/env python# import osfrom setuptools import find_packagesfrom distutils.core import setupfrom distutils.extension import Extensionfrom Cython.Build import cythonizedef read(fname):    return open(os.path.join(os.path.dirname(__file__), fname)).read()ext_modules = []ext_modules += [    Extension("lrec.evaluate.cy_ranking_metric", [              "lrec/evaluate/cy_ranking_metric.pyx"]),    Extension("lrec.utils.data_utils.data_cython_helpers", [        "lrec/utils/data_utils/data_cython_helpers.pyx"]),]setup(    name="LRec",    version="0.1",    author="Zhougongyu",    packages=find_packages(),    include_package_data=True,    zip_safe=False,    package_dir={'': '.'},    ext_modules=cythonize(ext_modules),).

3.使用命令pyx檔案產生build檔案找到c和pdy檔案

python setup.py   install 

4.把這三個放在一個檔案夾下如圖：

5.成功運行
