tensorflow_datasets failed to load dataset with data_dir="s3://<sagemaker-bucket>" in sagemaker notebook instance

[komushi]

I have been looking for an example to use tensorflow_datasets in sagemaker and found the following source. https://github.com/awslabs/sagemaker-debugger/blob/master/tests/tensorflow/test_keras_to_estimator.py

I believe this code - test_keras_to_estimator.py - works well with loading data to S3. Could you shed some light?

Thanks in advance

Btw, I am using tensorflow 2.3.0 with tensorflow_datasets 3.2.1.

The error I have is like below.

>>> dataset = tfds.load("iris", data_dir=s3_data_dir, split='train', as_supervised=True)
Downloading and preparing dataset iris/2.0.0 (download: 4.44 KiB, generated: Unknown size, total: 4.44 KiB) to s3://sagemaker-my-default-bucket/tensorflow_datasets/iris/2.0.0...

Some new information:

In Sagemaker Instance or Studio, if tfds.load is executed in the terminal or in the notebook it will fail. However if it is in the script mode of training it works fine.
