tf.raw_ops.Rank

Returns the rank of a tensor.

tf.raw_ops.Rank(
    input, name=None
)

This operation returns an integer representing the rank of input.

For example:

# 't' is [[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]]
# shape of tensor 't' is [2, 2, 3]
rank(t) ==> 3

input A Tensor.
name A name for the operation (optional).

A Tensor of type int32.
