Notebook fails on colab

[alasdairmotiv]

Thanks for sharing your work.
I tried running on colab with the T4 Gpu and it failed with the following error message while running "from pipeline import run_treelearn_pipeline":

Hello alasdairmotiv,

thanks for pointing this out! It seems that google colab changed their default environment, which means that we also have to change the setup part of the notebook. I was not immediately able to find a working solution, but will give it another try soon.
