Thanks for bringing this up! Earlier we had the feedback from the users saying that they don't want to spend time to learn yet another framework (referring to the monai.engines and monai.handlers mechanism), we therefore create those explicit forloop examples to show that many of the monai components work well in a 'vanilla' pytorch script.
Now we might have too many such examples. Perhaps we could address this after properly rearrange the examples #2 what do you think @Nic-Ma?

Sounds reasonable!
We should rearrange examples first then let's discuss the tutorials.
Thanks.
