用py2exe打包PyQt5+Matplotlib出错
打包Python3.4+PyQt5+Matplotlib程序，使用的py2exe打包，打包生成exe文件，运行出错，生成mymain1.log文件。错误信息

代码如下

sys.argv.append('py2exe')
py2exe_options = {
"includes": ["sip"], # 如果打包文件中有PyQt代码，则这句为必须添加的
"dll_excludes": ["MSVCP90.dll", ], # 这句必须有，不然打包后的程序运行时会报找不到MSVCP90.dll，如果打包过程中找不到这个文件，请安装相应的库

("platforms",
[r"C:\Python34\Lib\site-packages\PyQt5\plugins\platforms\qwindows.dll"])],
zipfile=None,
options={'py2exe': py2exe_options}
)用这个文件打包只有Python3.4+PyQt5的程序，没有问题
看错误信息 在ctypes库里没找到Py_DecRef这个函数
