CapacityError: Unable to provision compute capacity for training. Please reduce the number of jobs and try again.

I am trying to train a AWS Personalisation Model Recipe based Solution Version for the last 2 days but keep getting the below error continuously:

• CapacityError: Unable to provision compute capacity for training. Please reduce the number of jobs and try again.

I have tried the following when training a solution version but with no luck:

• Reduce the size of training data.
• Kick-off Solution Version training at odd hours (early morning, late night).

I am getting this issue in the ap-south-1 region
