Returns the size of a tensor.

tf.size(
    input, out_type=tf.dtypes.int32, name=None
)

See also tf.shape.

Returns a 0-D Tensor representing the number of elements in input of type out_type. Defaults to tf.int32.

For example:

t = tf.constant([[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]])
tf.size(t)
<tf.Tensor: shape=(), dtype=int32, numpy=12>

Args
input	A Tensor or SparseTensor.
name	A name for the operation (optional).
out_type	(Optional) The specified non-quantized numeric output type of the operation. Defaults to tf.int32.

Returns
A Tensor of type out_type. Defaults to tf.int32.
