NameError: name 'go' is not defined

最近在學習fbprophet時，按照安裝步驟，搭建好環境之后，使用官方教程進行學習。在執行到下面這句時報錯

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

 

具體報錯為：

NameError Traceback (most recent call last)
<ipython-input-20-42c219cbc949> in <module>
----> 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

 

解決方法：

如果已經安裝plotly，這里就不需要安裝了。

pip install plotly
pip install ipywidgets
