zipline package locally: doubts
Antonio Catalano
posted May 16, 2018

Today i created a venv in Python 3.5 in order to use the zipline package locally with Anaconda/Spyder.
I installed it with conda and installation seems to have gone well, but i have problems to find various modules of your tutorials.
For instance, the module 

from zipline.pipeline.data.psychsignal import stocktwits

, when i run the script in Spyder the output is an ImportError 'no module named zipline.pipeline.data.psychsignal'.
I tried even in other ways, like 'from zipline.pipeline.data.psychsignal import stocktwits_limited_free' but without success.

Another example is 

from zipline.algorithm import attach_pipeline

' and output is ImportError: cannot import name 'attach_pipeline'

I don't understand if i have to install other specific packages after i installed the quantopian zipline package or if there are limitations to use zipline locally.

Thank you

Antonio,

zipline is a library that powers our our simulations.

There are other elements of the Quantopian product that are not open sourced and included in zipline. One key element that is not included in zipline is the data from 3rd party providers such as Psychsignal or more generally the market data needed to simulate trading. As such, the lectures and educational content will work reliably with the development environments hosted and provided on the Quantopian site, but not when running locally.

If you'd like to follow our quant finance educational curriculum or use the tutorials, use the Quantopian site.

Thanks
Josh

But if i build a strategy with quantopian, then how can i use it in real trading if i'm not able to use some data? Must i buy them? Must i pay a subscriptiona?
How does it works the process that goes from simulations on this site to the real trading?
