I tried increasing the prefetch to 4 to make up for this, but no improvement. Here I ran with the first input pipeline for a bit and then with the map_and_batch.

2 for a batch size of 2), which can result in Out Of Memory Segfaults. The reason this does not work is because every tensor passed through tf.shape when utilizing map_and_batch has the same shape even though the contents of the tensor does not. This is not the case when executing map and batch separately, the last batch has a shape returned from tf.shape that correctly matches the shape of the value.
