Broker Not Found Error

[eudisd]

Dear Zipline Maintainers, From the zipline-live.io tutorial:

Installation of zipline-live works fine. Downloading the quandl bundle works fine as well. However, when I try to run the zipline-live demo program, with the following command:

zipline run -f ~/zipline-algos/demo.py --broker ib --broker-uri localhost:7496:1232 --bundle quantopian-quandl  --data-frequency minute

I get an error.

Thanks for the detailed report.

For some reason IbPy2 is not installed in your environment. pip install zipline-live[ib] should ensure that ibpy2 as a dependency is installed.

Please make a try to run pip install IbPy2==0.8.0 inside your virtualenvironment.

Unfortunately the error message is not helpful here (unsupported broker), we have an issue opened against that: https://github.com/zipline-live/zipline/issues/47

That did it! Thanks @tibkiss, this solved my problem. I think the problem this issue should address now is why IbPy2 is not installed when zipline-live is installed?

[tibkiss]

For others pip install zipline-live[ib] brings in IbPy2 as dependency, I'm not sure why did not bring it in for you. Could you please check and make sure you run that command?

In some shells (such as zsh) the zipline-live[ib] part should be quoted to properly pass the profile inside the braces: pip install "zipline-live[ib]"

[eudisd]

yup thats it i believe. i use zsh which caused the issue. thanks for the help, closing this issue
