Question

我正在尝试运行下面的代码并且它没有给我任何输出，而我所有其他Python程序（不使用Yahoo Finance Library）工作正常。我做错了什么？

import yahoo_finance
from pylab import *
import numpy as np
import scipy.signal as sc
import matplotlib.pyplot as plt
import pandas as pd
import datetime as dt

ticker = 'GLD'
begdate = '2014-11-11'
enddate = '2016-11-11'
data = yahoo_finance.Share('GLD')
data1 = data.get_historical(begdate,enddate)
gld_df = pd.DataFrame(data1)
date_df = pd.to_datetime((list(gld_df["Date"])))
adj_close_df = list(gld_df["Adj_Close"])
plt.plot(date_df,adj_close_df)
plt.title("SPDR Gold Shares ")

detrend = sc.detrend(adj_close_df)
plt.plot(date_df,detrend)
plt.title("SPDR Gold Detrend Prices")

这是我最终得到的错误。我是Python的新手，我不确定这意味着什么。

我使用的是Python3.x，Anaconda。该脚本昨天工作正常。

RemoteDisconnected: Remote end closed connection without response

Python Yahoo Finance没有提供输出
