Get list of observations -> make m_Observations public get #4634

Closed markste-in closed 3 years ago

markste-in commented 3 years ago

Is your feature request related to a problem? Please describe. I often haven the issue that I want to troubleshoot the learning behaviour by inspecting the observations that I added with sensor.AddObservation in CollectObservations(VectorSensor sensor). Right now I would need to add all observations manually to a list or something else to output / troubleshoot them later on.

Describe the solution you'd like The class VectorSensor in Unity.MLAgents.Sensors has already a list with all observations called: private List<float> m_Observations; It would be nice if we can change the private to a public get. That would give direct access to the observation without the need of handcrafting a workaround. public List<float> m_Observations { get; private set; }

Describe alternatives you've considered None

Additional context Even though the debugger gets you access to everything, it gives you just a snapshot in time and you have to manually click through every "hit" -> not really a solution especially if you have multiple agents

Does Agent.GetObservations() help you? Changelog 1.1.0-preview

ahh yes. Does exactly what I need... I don't know how I missed that.

Thanks!
