Question

我正在处理包括年，月和小时信息的时间序列数据。我正在尝试使用Python在Jupyter Notebook上使用此数据集预测未来。但是，当我运行运行prophet fit（）方法的单元格时，遇到了Runtime：初始化错误。我卸载并重新安装了Pandas，numpy，pystan和Prophet，但我不知道此错误的原因是什么。

我使用的代码如下：

from fbprophet import Prophet df1= df1.rename(columns={'record_date': 'ds', 'fullness_rate': 'y'}) fbp = fbprophet.Prophet() fbp.fit(df1)

和我的错误：

RuntimeError                              Traceback (most recent call 
last)
~/.local/lib/python3.6/site-packages/fbprophet/forecaster.py in

 1098             except RuntimeError:

During handling of the above exception, another exception occurred:
