Win10 安装pycocotools

1、获取源码：

(base) G:\>git clone https://github.com/pdollar/coco.git

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：

cl: 命令行 error D8021 :无效的数值参数“/Wno-cpp”
error: command 'H:\\VisualStudio2017\\install\\VC\\Tools\\MSVC\\14.15.26726\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

(base) G:\>pip install pycocotools

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
