Python Connector

Hi,
I'm getting the following error when tryring to run one of the connector's python files.  

C:\Users\Gal S\Desktop\rticonnextdds-connector-master\rticonnextdds-connector-ma
ster\examples\python\simple>reader.py
Traceback (most recent call last):

Did you came across with this attrbiuteError? How can I fix it?

Thanks in advance,
