SageMaker Canvas - Automate Batch Prediction <- without log in

As per AS documentation, you need to be logged in to run the automatic predictions. If you log out, the job will resume once you log back in.

You can only set up automatic batch predictions for datasets imported through local upload or Amazon S3. Additionally, automatic batch predictions can only run while you’re logged in to the Canvas application. If you log out of Canvas, the automatic batch prediction job resumes when you log back in.
