Chapter 2 Plot error

[shayegh]

Hi,
in chapter two, I follow your code but when I try to use "Plot"

# plot results
cerebro.plot(iplot=True, volume=False)

I got following error

ReferenceError: IPython is not defined

All other parts work as expected.

Hi,

Are you running the code from withing VS Code? This might somehow be an issue.
Please try running it in Jupyter Notebook/Lab and let me know if the problem persists.

Hi,
Thanks.
You were right. I ran it in vs code and got the error.
when I run it in Jupyter Notebook it works fine.
