djqgrid 0.2.4 error import json_helpers

[asimkon .]

Hello!

I want to use this wrapper <https://pypi.python.org/pypi/djqgrid/0.2.4> for
a module in my Django 1.9.4 version. I have configured all the steps
mentioned successfully but in the end i get the following error message in
my browser:

Invalid template library specified. ImportError raised when trying to
load 'djqgrid.templatetags.djqgrid': cannot import name json_helpers


Inside my templatetags folder  (djqgrid.py),  i have the following commands:

from django import template
from djqgrid import json_helpers

Any idea to get a solution ?

I sent a few emails to the author of this wrapper but i have not got a
reply yet!
