tf.broadcast_static_shape( shape_x, shape_y )
Computes the shape of a broadcast given known shapes.
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.
TensorShape representing the broadcasted shape.
ValueError: If the two shapes can not be broadcasted.
