|
|
#### com.unity.ml-agents (C#) |
|
|
|
#### ml-agents / ml-agents-envs / gym-unity (Python) |
|
|
|
- The minimum supported python version for ml-agents-envs was changed to 3.6.1. (#4244) |
|
|
|
- The minimum supported Python version for ml-agents-envs was changed to 3.6.1. (#4244) |
|
|
|
- The interaction between EnvManager and TrainerController was changed; EnvManager.advance() was split into to stages, |
|
|
|
and TrainerController now uses the results from the first stage to handle new behavior names. This change speeds up |
|
|
|
Python training by approximately 5-10%. (#4259) |
|
|
|
|
|
|
|
calls to `StatsRecorder.Add()` with the same key in the same step will no |
|
|
|
longer overwrite each other. (#4236) |
|
|
|
#### ml-agents / ml-agents-envs / gym-unity (Python) |
|
|
|
- The versions of `numpy` supported by ml-agents-envs were changed to disallow 1.19.0 or later. This was done to reflect |
|
|
|
a similar change in TensorFlow's requirements. (#4274) |
|
|
|
- Model checkpoints are now also saved as .nn files during training. (#4127) |
|
|
|
- Model checkpoint info is saved in TrainingStatus.json after training is concluded (#4127) |
|
|
|
- CSV statistics writer was removed (#4300). |
