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.

See https://github.com/pydata/pandas-datareader/issues

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：

The Google Finance API has not been stable since late 2017. Requests seem
to fail at random. Failure is especially common when bulk downloading.

Answer 1

here中讨论的一个小改动对我有用。只需使用

import pandas_datareader.data as web
sp500 = web.get_data_yahoo('SPY', start=start, end=end)

Answer 2

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。您是否已阅读this discussion有关API更改及其对熊猫的影响的信息？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每次有人尝试将Pandas用于Yahoo API时都引发ImmediateDeprecationError。 / p>

使用数据读取器时的InstantDeprecationError

很抱歉...
