Struct ObservationSpec

A description of the observations that an ISensor produces. This includes the size of the observation, the properties of each dimension, and how the observation should be used for training.

Syntax

public struct ObservationSpec

Constructors

Name	Description
ObservationSpec(InplaceArray<int>, InplaceArray<DimensionProperty>, ObservationType)	Create a general ObservationSpec from the shape, dimension properties, and observation type.

Properties

Name	Description
DimensionProperties	The properties of each dimensions of the observation. The length of the array must be equal to the rank of the observation tensor.
ObservationType	The type of the observation, e.g. whether they are generic or help determine the goal for the Agent.
Rank	The number of dimensions of the observation.
Shape	The size of the observations that will be generated. For example, a sensor that observes the velocity of a rigid body (in 3D) would use [3]. A sensor that returns an RGB image would use [Height, Width, 3].

Methods

Name	Description
VariableLength(int, int)	Construct an ObservationSpec for variable-length observations.
Vector(int, ObservationType)	Construct an ObservationSpec for 1-D observations of the requested length.
Visual(int, int, int, ObservationType)	Construct an ObservationSpec for visual-like observations, e.g. observations with a height, width, and possible multiple channels.
