   `dimension_property` is a tuple of flags containing extra information about how the
   data should be processed in the corresponding dimension. `type` is an enum
   corresponding to what type of sensor is generating the data (i.e., observation, goal,
-  etc). Note that the `SensorSpec` have the same ordering as the ordering of observations 
+  etc). Note that the `SensorSpec` have the same ordering as the ordering of observations
   in the DecisionSteps, DecisionStep, TerminalSteps and TerminalStep.
 - `action_spec` is an `ActionSpec` namedtuple that defines the number and types
   of actions for the Agent.
