trying to plot the decision tree graph in google colab

[David Diaz]

Hello everyone,

I'm trying to do as mentioned, you can find my code here (I'm preparing lesson for an introductory course of machine learning to business students)

https://colab.research.google.com/drive/1f0YjltIUMQdjgVaTSCxZd_8_GFch8D1e?usp=sharing#scrollTo=S-nWhQ0I-626

is the last cell which runs but doesnt show the plot

Thanks in advance,

kind regards

pww3 wasn't designed with jupyter notebooks in mind. That command would pop up a matplotlib window, which probably doesn't work in a notebook.

Have you tried saving the plot to a file instead and then loading/displaying that in a cell?

The plot_dot_graph method has a "filename" parameter for that:

Thanks, that's what I did (saving the file to disk and then plot it from the .png)

kind regards!
