tfp.math.dense_to_sparse

Converts dense Tensor to SparseTensor, dropping ignore_value cells.

tfp.math.dense_to_sparse(
    x,
    ignore_value=None,
    name=None
)

Defined in python/math/sparse.py.

Args:

  • x: A Tensor.
  • ignore_value: Entries in x equal to this value will be absent from the return SparseTensor. If None, default value of x dtype will be used (e.g. '' for str, 0 for int).
  • name: Python str prefix for ops created by this function.

Returns:

  • sparse_x: A tf.SparseTensor with the same shape as x.

Raises:

  • ValueError: when x's rank is None.
