我正在玩Enigma Catalyst.不幸的是,文档相当有限.

所以我试图运行他们的示例"hello world"类型algo,如下所示:

from catalyst import run_algorithm
from catalyst.api import order, record, symbol
import pandas as pd

def initialize(context):
    context.asset = symbol('btc_usd')


def handle_data(context, data):
    order(context.asset, 1)
    record(btc=data.current(context.asset, 'price'))


if __name__ == '__main__':
    run_algorithm(
        capital_base=10000,
        data_frequency='daily',
        initialize=initialize,
        handle_data=handle_data,
        exchange_name='Bitfinex',
        algo_namespace='buy_and_hodl',
        base_currency='usd',
        start=pd.to_datetime('2018-01-02', utc=True),
        end=pd.to_datetime('2018-01-03', utc=True),
    )

我意识到根据文档说它首先需要"摄取"下载我认为我做过的历史数据.但是,这会导致以下错误:

这导致没有数据
