ClientError: An error occurred (ValidationException) when calling the CreateTransformJob operation: No S3 objects found under S3 URL "s3://sagemaker-us-west-2-521695447989/image-classification-full-training/test/" 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".

Start with introduction_to_amazon_algorithms/imageclassification_caltech/Image-classification-fulltraining.ipynb and inspect the code around In [11], where CreateTransformJob fails. Reproduce the CI run and trace the referenced S3 input path and permissions from the error. Done means the notebook completes CI without the reported missing-S3-objects validation error.
