Solution for someone if encounters "TypeError: <class '__main__.XxxClass'> is a built-in class" in Jupyter #30

In Jupyter you may try to plot to single browser tab with iplot=False:

plot = btplotting.BacktraderPlotting()
cerebro.plot(plot, iplot=False)

You may encounters TypeError: <class '__main__.YourStrategyClass'> is a built-in class error.

Then try this:

plot = btplotting.BacktraderPlotting()
plot.tabs.remove(btplotting.tabs.SourceTab)
cerebro.plot(plot, iplot=False)
