A batching transformation that omits the final small batch (if present). (deprecated)
tf.contrib.data.batch_and_drop_remainder(
batch_size
)
Like tf.data.Dataset.batch
, this transformation combines
consecutive elements of this dataset into batches. However, if the batch
size does not evenly divide the input dataset size, this transformation will
drop the final smaller element.
The following example illustrates the difference between this
transformation and Dataset.batch()
:
dataset = tf.data.Dataset.range(200)
batched =
dataset.apply(tf.contrib.data.batch_and_drop_remainder(128))
print(batched.output_shapes) # ==> "(128,)" (the batch dimension is known)
By contrast, dataset.batch(128)
would yield a two-element dataset with
shapes (128,)
and (72,)
, so the batch dimension would not be statically
known.
