OlivierCR:

It is an optional parameter of the Python SDK Estimators, set by default to 86400s (1 day).


I see in the doc about MaxRuntimeInSeconds 1 the 1 day as default value but it says 28 days in maximum:

The default value is 1 day. The maximum value is 28 days.

And when I search for the 5 days you mention in your post, I find this page in AWS SageMaker doc that confirms it:

Longest run time for a processing job: 5 days

What is the right value as a maximum for a training/processing job?
