python3 import zookeeper module    import
I recently import the zookeeper module in python 3,so when I finished my work, I made a mistake in testing the import of the zookeeper module.  

The error message is :
ImportError: /usr/local/lib/python3.5/dist-packages/zookeeper.cpython-35m-x86_64-linux-gnu.so: undefined symbol: PyInt_AsLong   
I'm using the system of linux-ubuntu.

I don't know how to solve this problem. Thanks!
