Seeking Help

Hi, I am trying to run the demo after installing zipline-live using python2.7 in a virtualenv but cannot get past this issue.

$ zipline run -f ~/zipline-algos/demo.py --state-file ~/zipline-algos/demo.state --realtime-bar-target ~/zipline-algos/realtime-bars/ --broker ib --broker-uri localhost:4002:1232 --bundle quantopian-quandl --data-frequency minute

I'm having the same issue. Has anyone found a resolution? I have tried both the 1.6.1 and 1.7 versions of trading-calendars, no dice.

I joined the Slack channel and found the suggestion to add the XNYS alias to calendar_utils.py. Resolved my issue a few seconds.
