Bug Academy EpisodeCount always return 1

When displaying some stats on a UI canvas during training/inference I noticed the EpisodeCount always returns 1, while other properties on the academy return correctly.

Here is the UI display code I'm using -

Code (CSharp):

1. using Unity.MLAgents;
2. using UnityEngine;
3. using UnityEngine.UI;
4.  
5. public class AcademyStats : MonoBehaviour
6. {
7.     public Text Episode;
8.     public Text TotalSteps;
9.  
10.     // Update is called once per frame
11.     public void Update()
12.     {
13.         if (Academy.IsInitialized)
14.         {
15.             Episode.text = "Episode: " + Academy.Instance.EpisodeCount;
16.             TotalSteps.text = "Total Steps: " + Academy.Instance.TotalStepCount;
17.         }
18.     }
19. }
20.  

When run the UI looks like this -

You can see the agent resetting itself and the episode's completed by this agent being incremented. On the right however the academy episode stays the same.

Version information:
ml-agents: 0.19.0 (release_6),
ml-agents-envs: 0.19.0,
Communicator API: 1.0.0,
TensorFlow: 2.3.0
Unity: 2020.2.0a21.2837

 

Ah that makes more sense, thank you!

A quick follow up, would the environment reset automatically in a curriculum change or must that be done manually?

 

A quick explanation for anyone else who checks this out, you can see in my gif (bottom left) that Agent01's episodes increment with each reset of the agent. My incorrect assumption was that the Academy EpisodeCount (bottom right) was an aggregate of all agent episodes within the environment (like the total step count is for steps). However the environment has its own episode count that gets incremented as explained by christophergoy.

 

If I create 16 independent fields for agents to train. Do I have to sum up all 16 CompletedEpisodes to get the total episode number of my training?
I think this number should be available in the academy, not calculate by the user. And EpisodeCount seems useless because it always returns 1, which we don't care about.
