I'm trying to run a simple piece of code using pyzmq. I am using Python 2.7 and pyzmq 14.5
$ python --version
Python 2.7.6
$ sudo find /usr -name "*pyzmq*"
/usr/local/lib/python2.7/dist-packages/pyzmq-14.5.0.egg-info
/usr/lib/python2.7/dist-packages/pyzmq-14.0.1.egg-info
Following is the code i'm trying to run:
import zhelpers
context = zmq.Context.instance()
server = context.socket(zmq.ROUTER)
server.bind("tcp://*:5678")
while (1):
address, empty, data = server.recv_multipart()
print("address = %s, data = %d" % (address, int(data)))
data_i = int(data) + 10
server.send_multipart([
address,
b'',
str(data_i),
])
But, I'm getting following error and got no clue how to fix this:
Traceback (most recent call last):

from . import (constants, error, message, context, socket, utils, _poll, _version, _device)
ImportError: cannot import name constants
I've copied the whole zmq folder and placed it in the level as my .py file.
Please help!
EDIT:
I've removed those two versions of pyzmq and reinstalled latest pyzmq (with libzmq bundled this time) as instructed here.
$ sudo find /usr -name "*pyzmq*"
/usr/local/lib/python2.7/dist-packages/pyzmq-14.7.0-py2.7.egg-info
$ sudo find /usr -name "*libzmq*"
/usr/local/lib/libzmq.so
/usr/local/lib/libzmq.la
/usr/local/lib/libzmq.so.5.0.0
/usr/local/lib/pkgconfig/libzmq.pc
/usr/local/lib/libzmq.so.5
/usr/local/lib/python2.7/dist-packages/zmq/libzmq.so
/usr/local/lib/python2.7/dist-packages/zmq/backend/cython/libzmq.pxd
/usr/local/lib/libzmq.a
But this doesn't solve the problem. I'm getting the same error!
