python代码内存溢出报错

环境是

4核+8G的7.3CentOS系统(强调，系统是64位的)

这种内存溢出错误。一旦报错就是一堆堆的报错，完全找不到头绪，

找了好久发现这种错误主要是两点原因。

1.Python解释器是32位的（或者只支持32位），当内存使用率到了2GB以上之后，就会内存溢出，好比   java设置了2G

2.代码级别的循环调用，百度一下有很多这个原因的。

 

解决方案重新编译安装python解释器

 

./configure --prefix=/usr/local/python3.6.2 --with-ssl --with-universal-archs=all

make

make install

　　

其中 --with-universal-archs=all  

select architectures for universal build ("32-bit","64-bit", "3-way", "intel", "intel-32", or "all")

选择 architectures进行构建，然后我选择了all进行构建。其中 intel是英特尔芯片的意思。
