    input,
    name=None,
    out_type=tf.int32
)

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

See the guide: Tensor Transformations > Shapes and Shaping

Returns the size of a tensor.

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)  # 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.
