Not plotting in Jupyter Notebook?

[eugeneyng]

Hi all,
Anybody experiencing a problem with Bokeh not plotting in Jupyter? I'm running the minimal example with Python 3.7.3, Jupyter Notebook 6.1.5, and Bokeh 2.3.0. I looked at some closed issues but the only solution was setting this line

backtesting.set_bokeh_output(notebook=False)

I tried true and false and neither worked. Anybody else having the same issue?

`
# In[1]:

  import backtesting
  import backtesting.lib
  import backtesting.test
  backtesting.set_bokeh_output(notebook=False)
  
  # In[2]:
  
  class SmaCross(backtesting.Strategy):
      n1 = 10
      n2 = 20
  
      def init(self):
          close = self.data.Close
          self.sma1 = self.I(backtesting.test.SMA, close, self.n1)
          self.sma2 = self.I(backtesting.test.SMA, close, self.n2)
  
      def next(self):
          if backtesting.lib.crossover(self.sma1, self.sma2):
              self.buy()
          elif backtesting.lib.crossover(self.sma2, self.sma1):
              self.sell()
  
  # In[3]:
  
  bt = backtesting.Backtest(backtesting.test.GOOG, SmaCross,
                cash=10000, commission=.002,
                exclusive_orders=True)
  bt.run()
  
  # In[4]:
  
  bt.plot()

I will say I am running the notebook on a Raspberry Pi and hosting the notebook publicly so that I can access it from my computer. Believe this is the issue. It's noted that I can set backtesting.set_bokeh_output(notebook=False) to False and can then open the html file separately. For now this is a fine workaround. Sorry if I'm taking up space on the forums here!

backtesting.set_bokeh_output(notebook=True) should be a working default for Jupyter notebooks.

The Bokeh resources are loaded from their remote CDN. Do you run an ad-blocker perhaps?

You should see an image like this upon any first backtesting import:
