白噪声LB检验报错FutureWarning解决方案

import statsmodels.api as sm
jy=sm.stats.diagnostic.acorr_ljungbox(varepsilon_values_1, lags = [6, 12],boxpierce=True)
print(jy)

在对一个时间序列进行白噪声LB检验时，出现报错：

D:\Anaconda3\lib\site-packages\statsmodels\stats\diagnostic.py:559: FutureWarning: The value returned will change to a single DataFrame after 0.12 is released.  Set return_df to True to use to return a DataFrame now.  Set return_df to False to silence this warning. me after 0.12 is released.  Set return_df to True t
  warnings.warn(msg, FutureWarning)

进入源代码报错位置检查，发现是由于return_df没有设置，默认为None，源代码中设置了return_df==None报错，故，

解决方案，在函数中加上参数return_df=bool：

jy=sm.stats.diagnostic.acorr_ljungbox(varepsilon_values_1, lags = [6, 12],boxpierce=True,return_df =bool)
