Say if I have a data that I got from running a pipeline i.e.
my_pipe = make_pipeline() data = run_pipeline(my_pipe, '2014-05-05', '2015-05-05')
How do I get, for example, data for only AAPL equity? In Pipeline result, looks like equities are
zipline.assets._assets.Equity objects and we are not allowed to run
from zipline.assets._assets import Equity. How else do I create Equity object?
