SageMaker Script Mode + Pipe Mode

I'm training in SageMaker using TensorFlow + Script Mode and currently using 'File' input mode for my data.

Has anyone figured out how to stream data using 'Pipe' data format in conjunction with Script Mode training?

You can import sagemaker_tensorflow from the training script as follows:

from sagemaker_tensorflow import PipeModeDataset
from tensorflow.contrib.data import map_and_batch

channel = 'my-pipe-channel-name'

ds = PipeModeDataset(channel)
ds = ds.repeat(EPOCHS)
ds = ds.prefetch(PREFETCH_SIZE)
ds = ds.apply(map_and_batch(parse, batch_size=BATCH_SIZE,
                            num_parallel_batches=NUM_PARALLEL_BATCHES))

You can find the full example here: https://github.com/awslabs/amazon-sagemaker-examples/blob/master/sagemaker-python-sdk/tensorflow_pipemode_example/pipemode.py

You can find documentation about sagemaker_tensorflow here https://github.com/aws/sagemaker-tensorflow-extensions#using-the-pipemodedataset
