**What did you find confusing? Please describe.** I'm documenting file mode and storage options for SageMaker training. https://sagemaker.readthedocs.io/en/stable/frameworks/tensorflow/using_tf.html?highlight=input%20mode#training-with-pipe-mode-using-pipemodedataset This page provides an example of Pipe mode, and I see `PipeModeDataset` is used in the training script. However, I cannot find this class in the doc and source code. I also it's imported from `sagemaker_tensorflow`, which seems not existing either. Can some clarify if this class does not exist, and if so, would you remove the related portion from the page?
