ClientError: An error occurred (ValidationException) when calling the CreateTrainingJob operation: No S3 objects found under S3 URL "s3://sagemaker-us-west-2-521695447989/image-classification/train/" given in input data source. Please ensure that the bucket exists in the selected region (us-west-2), that objects exist under that S3 prefix, and that the role "arn:aws:iam::521695447989:role/ProdBuildSystemStack-ReleaseBuildRoleFB326D49-QK8LUA2UI1IC" has "s3:ListBucket" permissions on bucket "sagemaker-us-west-2-521695447989".

Open aws_sagemaker_studio/sagemaker_algorithms/imageclassification_caltech/Image-classification-lst-format.ipynb and inspect the cells before In [10], especially the S3 input setup and training_params. Reproduce the failing training-job call in the indicated us-west-2 environment, then verify the notebook's CI run no longer reports missing S3 objects.
