I am using TPU runtime in Google Colab, and I know tpu runtimes can only access data in GCS as only the GCS file system is registered.
However I found StreamingFilesDataset can read tfrecord file from local.(https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/tpu/datasets.py#L52 6)
I wrote like this
from tensorflow.python.tpu import datasets as tf_tpu_ds
tf_tpu_ds.StreamingFilesDataset( dataset_path, ‘tfrecord’, file_reader_job=‘localhost’)
Then I got

AttributeError: ‘OwnedIterator’ object has no attribute ‘string_handle’

‘string_handle’ seems tensorflow version 1 function.
So, Is StreamingFilesDataset version 1 only supported, or bugs?
