Computes the shape of a broadcast given known shapes.

Aliases:

  • tf.compat.v2.broadcast_static_shape
 tf.broadcast_static_shape(
    shape_x,
    shape_y
)

When shape_x and shape_y are fully known TensorShapes this computes a TensorShape which is the shape of the result of a broadcasting op applied in tensors of shapes shape_x and shape_y. For example, if shape_x is [1, 2, 3] and shape_y is [5, 1, 3], the result is a TensorShape whose value is [5, 2, 3]. This is useful when validating the result of a broadcasting operation when the tensors have statically known shapes.

Args:

  • shape_x: A TensorShape
  • shape_y: A TensorShape

Returns:

A TensorShape representing the broadcasted shape.

Raises:

  • ValueError: If the two shapes can not be broadcasted.
