Ipython Magic For Zipline Cannot Find Data Bundle

I have a Python 2.7 script that runs Zipline fine on the command prompt, using --bundle=myBundle to load the custom data bundle myBundle which I have registered using extension.py.

Solution 1:

It is a known (now closed) bug in zipline, see also https://github.com/quantopian/zipline/issues/1542.

As a workaround you can load the following in the cell before the zipline magic:

import os

from zipline.utils.run_algo import load_extensions

load_extensions(
    default=True,
    extensions=[],
    strict=True,
    environ=os.environ,
)
