tf.sets.size(
    a,
    validate_indices=True
)

Defined in tensorflow/python/ops/sets_impl.py.

Compute number of unique elements along last dimension of a.

Args:

• a: SparseTensor, with indices sorted in row-major order.
• validate_indices: Whether to validate the order and range of sparse indices in a.

Returns:

int32 Tensor of set sizes. For a ranked n, this is a Tensor with rank n-1, and the same 1st n-1 dimensions as a. Each value is the number of unique elements in the corresponding [0...n-1] dimension of a.

Raises:

• TypeError: If a is an invalid types.
