What i am doing wrong??

Sorry, I misread your description and attributed the same cause as #20 - looks like your problem is actually different.

Did you install with pip or python setup.py install ?

I would be inclined to try:

$ sudo rm -rf /usr/local/lib/python2.7/dist-packages/luma*
$ sudo -H pip install -U luma.led_matrix

And then try the example again

Have a look at the documentation, especially this section: http://luma-led-matrix.readthedocs.io/en/latest/install.html#installing-from-pypi

It shows you how to install pip and all the other pre-requisites.
