tf.broadcast_dynamic_shape(
    shape_x,
    shape_y
)

When shape_x and shape_y are Tensors representing shapes (i.e. the result of calling tf.shape on another Tensor) this computes a Tensor 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 Tensor whose value is [5, 2, 3].

This is useful when validating the result of a broadcasting operation when the tensors do not have statically known shapes.

Args:

• shape_x: A rank 1 integer Tensor, representing the shape of x.
• shape_y: A rank 1 integer Tensor, representing the shape of y.

Returns:

A rank 1 integer Tensor representing the broadcasted shape.
