🔧 Bug Fixes
- #### com.unity.ml-agents (C#)
- Fix a compile warning about using an obsolete enum in `GrpcExtensions.cs`. (#4812)
- CameraSensor now logs an error if the GraphicsDevice is null. (#4880)
- Removed unnecessary memory allocations in `ActuatorManager.UpdateActionArray()` (#4877)
- Removed unnecessary memory allocations in `SensorShapeValidator.ValidateSensors()` (#4879)
- Removed unnecessary memory allocations in `SideChannelManager.GetSideChannelMessage()` (#4886)
- Removed several memory allocations that happened during inference. On a test scene, this
- reduced the amount of memory allocated by approximately 25%. (#4887)
- Removed several memory allocations that happened during inference with discrete actions. (#4922)
- Properly catch permission errors when writing timer files. (#4921)
- Unexpected exceptions during training initialization and shutdown are now logged. If you see
- "noisy" logs, please let us know! (#4930, #4935)
- #### ml-agents / ml-agents-envs / gym-unity (Python)
- Fixed a bug that would cause an exception when `RunOptions` was deserialized via `pickle`. (#4842)
- Fixed a bug that can cause a crash if a behavior can appear during training in multi-environment training. (#4872)
- Fixed the computation of entropy for continuous actions. (#4869)
- Fixed a bug that would cause `UnityEnvironment` to wait the full timeout
- period and report a misleading error message if the executable crashed
- without closing the connection. It now periodically checks the process status
- while waiting for a connection, and raises a better error message if it crashes. (#4880)
- Passing a `-logfile` option in the `--env-args` option to `mlagents-learn` is
- no longer overwritten. (#4880)
- The `load_weights` function was being called unnecessarily often in the Ghost Trainer leading to training slowdowns. (#4934)
