objgraph 是用于诊断内存问题的有用的工具
安装objgraph
sudo pip install objgraph
用小段测试代码，生成png格式的分析图片
#encoding=utf-8
import objgraph
def main(hi):
print hi
if __name__ == '__main__':
hi = 'hi'
main(hi)
objgraph.show_backrefs([hi], filename='/tmp/hi.png')
会出现错误
Graph written to /tmp/objgraph-Nieb4E.dot (6 nodes) Graph viewer (xdot) and image renderer (dot) not found, not doing anyt hing else
原因: 缺少依赖包
sudo yum install python-xdot perl-Image-Dot

如果是在windows的情况下呢？

我安装了xdot，还是和你一样的错误

@N: 用objgraph生成的图不容易看懂，推荐python的meliae
