python-zipline中没有这样的选项错误

Question

I am a newbie to zipline. I am following the beginner tutorial to get familiar with it. And when I tried to run the algorithm as taught by tutorial in the ipython cell:

from zipline.api import order_target, record, symbol, history
import numpy as np
import pandas as pd

from zipline.examples import buyapple
%load_ext zipline
%%zipline --start 2000-1-1 --end 2014-1-1 --symbols AAPL


def initialize(context):
    pass

def handle_data(context, data):
    order(symbol('AAPL'), 10)
    record(AAPL=data[symbol('AAPL')].price)

I got such an error: NoSuchOption: no such option: --symbols

I tried to run python -m zipline run -f ../../zipline/examples/buyapple.py --start 2000-1-1 --end 2014-1-1 --symbols AAPL -o buyapple_out.pickle in the cli and also got the same error. Do you know what's the reason and how can I fix it? Thank you in advance!

Answer 1

I ran this command $ zipline ingest which defaulted to fetching quantopian-quandl data bundle.

After that finished downloading I removed the offending switch: --symbols AAPL and the tutorial seemed to run correctly.
