NameError: name 'go' is not defined

最近在学习fbprophet时,按照安装步骤,搭建好环境之后,使用官方教程进行学习。在执行到下面这句时报错

fig = plot_plotly(m, forecast)  # This returns a plotly Figure

具体报错为:

NameError                                 Traceback (most recent call last)
 in 
----> 1 fig = plot_plotly(m, forecast)  # This returns a plotly Figure

~/anaconda3/lib/python3.7/site-packages/fbprophet/plot.py in plot_plotly(m, fcst, uncertainty, plot_cap, trend, changepoints, changepoints_threshold, xlabel, ylabel, figsize)
    566     data = []
    567     # Add actual
--> 568     data.append(go.Scatter(
    569         name='Actual',
    570         x=m.history['ds'],

NameError: name 'go' is not defined

解决方法:

如果已经安装plotly,这里就不需要安装了。

pip install plotly
pip install ipywidgets
