tft.sparse_tensor_left_align

Re-arranges a tf.SparseTensor and returns a left-aligned version of it.

tft.sparse_tensor_left_align(
    sparse_tensor: tf.SparseTensor
) -> tf.SparseTensor

This mapper can be useful when returning a sparse tensor that may not be left-aligned from a preprocessing_fn.

Args
sparse_tensor	A 2D tf.SparseTensor.

Raises
ValueError if sparse_tensor is not 2D.

Returns
A left-aligned version of sparse_tensor as a tf.SparseTensor.
