How do I create padded batches in Tensorflow for tf.train.SequenceExample data using the DataSet API?

Question

For training an LSTM model in Tensorflow, I have structured my data into a tf.train.SequenceExample format and stored it i

Answer 1

You need to pass a tuple of shapes. In your case you should pass

dataset = dataset.padded_batch(4, padded_shapes=([vectorSize],[None]))

or try

dataset = dataset.padded_batch(4, padded_shapes=([None],[None]))

Check this code for more details. I had to debug this method to figure out why it wasn't working for me.
