Python autoarima参数选择过程-ARIMA/SARIMAX

是否有任何方法可以阻止auto_arima函数达到产生无限aic的组合。我使用的是逐步搜索，不可能使用最大顺序作为参数。这是我的密码

 from pmdarima.arima import ndiffs,nsdiffs
 test_df = grouped_df.get_group(items[k])
 X = test_df['Quantity'].values
 train, test = X[0:len(X)-1], X[len(X)-1:]

 try:
     nsdiffs_D = nsdiffs(X,m=52)
     ndiffs_d = ndiffs(X,alpha=0.05)
     stepwise_fit = auto_arima(train, start_p=0, start_q=0,
                           max_p=6, max_q=6,m=52,
                           start_P=0,seasonal=True,alpha=0.05,
                           d=ndiffs_d,D=nsdiffs_D,trace=True,n_jobs=-1,
                           error_action='ignore',stepwise=True,suppress_warnings=True)

在参数搜索中，大多数给出无限AIC的组合都是花费太多时间的组合。我正在对2000多个产品进行网格搜索，当auto arima对其中许多产品花费太多时间时，这是没有用的。关于如何加快网格搜索过程，有什么建议吗。这里是一个网格搜索的输出
