tf.rank(
input,
name=None
)
Defined in tensorflow/python/ops/array_ops.py.
Returns the rank of a tensor.
Returns a 0-D int32 Tensor representing the rank of input.
For example:
# shape of tensor 't' is [2, 2, 3]
t = tf.constant([[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]])
tf.rank(t) # 3
Note: The rank of a tensor is not the same as the rank of a matrix. The rank of a tensor is the number of indices required to uniquely select each element of the tensor. Rank is also known as "order", "degree", or "ndims."
Args:
input: ATensororSparseTensor.name: A name for the operation (optional).
Returns:
A Tensor of type int32.
