Extending from our conversation just now on a MONAI 201 notebook, I used this pattern with the bundle tutorials with 03_mednist_classification_v2.ipynb. This is the pattern I'd suggest of a lesson building on a previous one.

Hi @ericspod, do you think for this one we also need to add another tutorial since there only three lines were added? https://github.com/Project-MONAI/tutorials/blob/39ecb41b480cf2438a3e3d4da9119a2cc26b89a1/2d_classification/mednist_tutorial.ipynb

For this notebook maybe these additions are fine, the monai_101.ipynb was the super-simple notebook I wanted to keep small. Since you're using Tensorboard, is there something that can be added to demonstrate that data within the notebook? I don't know if including Tensorboard in the notebook will render correctly in Github.

Hi @ericspod, I have added this part, could you please help review it again, thanks!
