使用数据读取器时的InstantDeprecationError

Question

import datetime as dt

from matplotlib import style

import pandas as pd

import pandas_datareader.data as web

style.use('ggplot')

start = dt.datetime(2000,1,1)

end = dt.datetime(2016,12,31)

df = web.DataReader('INPX', 'yahoo', start, end)

ImmediateDeprecationError: 

Yahoo Daily has been immediately deprecated due to large breaks in the API without the

introduction of a stable replacement. Pull Requests to re-enable these data

connectors are welcome.

我尝试了链接，但是找不到立即折旧错误的原因。我还尝试将'yahoo'更改为'google'，即：df = web.DataReader（'INPX'，'google'，开始，结束），但仍然存在错误：

/anaconda3/lib/python3.6/site-packages/pandas_datareader/google/daily.py:40: UnstableAPIWarning: 

The Google Finance API has not been stable since late 2017. Requests seem

to fail at random. Failure is especially common when bulk downloading.

warnings.warn（UNSTABLE_WARNING，UnstableAPIWarning）

Answer 1

只需使用import pandas_datareader.data as websp500 = web.get_data_yahoo('SPY', start=start, end=end)

Answer 2

该错误是不言自明的。Yahoo API已更改，因此从Yahoo API读取的旧的Pandas代码不再起作用。你读过这个讨论有关API的变化及其对大熊猫的影响？本质上，Pandas无法读取新的Yahoo API，并且将花费很长时间来编写新代码，因此临时解决方案是在ImmediateDeprecationError每次有人尝试将Pandas用于Yahoo API时提出建议。
