Zipline的iPython魔术无法找到数据包 [英] iPython magic for Zipline cannot find data bundle

问题描述

我有一个Python 2.7脚本，可以在命令提示符下运行Zipline，使用 - bundle = myBundle 来加载自定义数据包 myBundle 我使用 extension.py 注册。

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.

zipline run -f myAlgo.py --bundle=myBundle --start 2016-6-1 --end 2016-7-1 --data-frequency=minute

问题：但是当我尝试使用％zipline IPython magic时要运行该算法，bundle参数 - bundle 似乎很难找到 myBundle 。

Problem: However when I try to use the %zipline IPython magic to run the algorithm, the bundle argument --bundle seems to have difficulty finding myBundle.

%zipline --bundle=myBundle--start 2016-6-1 --end 2016-7-1 --data-frequency=minute

运行此将产生错误

UnknownBundle: No bundle registered with the name u'myBundle'

我们是否使用IPython笔记本时必须以不同方式注册包吗？

Do we have to register the bundle differently when using IPython notebook?

推荐答案

这是zipline中已知（现已关闭）的错误，另见 https://github.com/quantopian/zipline/issues/1542 。

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

作为一种解决方法，您可以在单元格中加载以下内容zipline magic：

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,
)
