Hey Hii Shivani,
Great article to get oneself introduced to AWS Sagemaker.
I was facing this issue when I tried to run the model.fit command in the AWS Jupyter Notebook in AWS Sagemaker.
ResourceLimitExceeded: An error occurred (ResourceLimitExceeded) when calling the CreateTrainingJob operation: The account-level service limit 'ml.p3.2xlarge for training job usage' is 0 Instances, with current utilization of 0 Instances and a request delta of 1 Instances. Please contact AWS support to request an increase for this limit.
Could you let me know what additional steps you took for resolving this?
