Continuous vector represented as a float tensor.

create ~low ~high creates a continuous space with bounded ranges.

Valid values are tensors where each element i satisfies low.(i) <= x.(i) <= high.(i). Arrays low and high must have the same length, defining the space dimensionality.

Common use: Observation spaces for continuous state (e.g., position, velocity) or continuous action spaces (e.g., torque, steering angle).

• raises Invalid_argument

  if low and high have different lengths or if any low.(i) > high.(i).
