如何解决AttributeError：模块'pandas'没有属性'ewma'？

Question

我遇到的熊猫属性错误：0.24.2

expwighted_avg = pd.ewma(ts_log, halflife=12)

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-67-cbd5d537822b> in <module>()
----> 1 expwighted_avg = pd.ewma(ts_log, halflife=12)

AttributeError: module 'pandas' has no attribute 'ewma'

Answer 1

对我来说，现在可以正常工作并且代码可以成功运行

    expwighted_avg = ts_log.ewm(halflife=12).mean()
