2、安装

(base) G:\>cd coco/PythonAPI

(base) G:\coco\PythonAPI>python setup.py build_ext --inplace

发现报错，主要内容为：

解决方法：

打开coco\PythonAPI目录下的 setup.py文件，修改ext_modules  extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'],

修改如下：

--------------------------------------------------------------

from setuptools import setup, Extension

import numpy as np

# To compile and install locally run "python setup.py build_ext --inplace"

# To install library to Python site-packages run "python setup.py build_ext install"

ext_modules = [

 Extension(

   'pycocotools._mask',

   sources=['../common/maskApi.c', 'pycocotools/_mask.pyx'],

   include_dirs = [np.get_include(), '../common'],

   #修改位置，去掉

   #extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'],

   extra_compile_args=['', '', ''],

 )

]

setup(

 name='pycocotools',

 packages=['pycocotools'],

 package_dir = {'pycocotools': 'pycocotools'},

 install_requires=[

   'setuptools>=18.0',

   'cython>=0.27.3',

   'matplotlib>=2.1.0'

 ],

 version='2.0',

 ext_modules= ext_modules

)

--------------------------------------------------------------

然后保存setup.py文件

然后继续执行

(base) G:\coco\PythonAPI>python setup.py build_ext --inplace
