I'm using a virtualenv. Where should Zipline's extension.py be?

Question

I'm a newbie to zipline and I'm trying to reproduce this example loosely. It calls for modifying a file .zipline/extension.py. Fat luck, I do not have this file.

Now, I can do (from inside the virtualenv):

(Mony_games) me@me-ThinkPad-T470p:~/$ ipython
import zipline
zipline.utils.paths.default_extension()

But this points to

'/home/me/.zipline/extension.py'

which doesn't exist. Do I have to create it? If so, where: I'm a bit confused because I'm using a virtualenv, so:

import inspect
inspect.getfile(zipline)
'/home/me/virtualenvs/Mony_games/lib/python3.5/site-packages/zipline/__init__.py'

Answer 1

it's okay. virtualenv or not, this file should be where

import zipline
zipline.utils.paths.default_extension()

points to, which in my case is:

'/home/me/.zipline/extension.py'

Answer 2

Your virtualenv doesn't know anything about ipython. To verify, open ipython and enter:

import sys
sys.executable

The python executable will be your global python.

If you put your script in a file, you can execute the file with python myfile.py and that will use the python executable in your virtualenv.
