|
| Modifications by ccnets (stated per Apache-2.0 section 4b): |
| - The Unity builds under `Crawler/`, `3DBallHard/`, `PushBlock/`, `Pyramids/`, |
| `Worm/`, `Walker/`, `DungeonEscape/`, and `SoccerTwos/` were produced from |
| customized ML-Agents projects derived from `ml-agents-release_23`. |
| - Each build's baked-in policy was removed so the build accepts actions from |
| an externally supplied policy at run time. |
| - `SoccerTwos.onnx` derives from the release-23 SoccerTwos stock policy. Its |
| dangling output declarations, which referenced no graph values, were removed |
| for compatibility with current ONNX Runtime. The computation graph and |
| learned parameters were not changed. |
| - The `tier_policies/` files derive from the release-23 stock policies of the |
| same name, re-exported to additionally expose their pre-softmax `logits` |
| output (`norm_logits` as well for PushBlock and Pyramids). The learned |
| parameters and the pre-existing outputs were not changed |
| lets a softmax temperature synthesize the calibrated `medium` / `simple` |
| dataset tiers. |
| - The `Crawler/`, `3DBallHard/`, and `PushBlock/` builds additionally carry |
| Unity Barracuda assemblies (`Unity.Barracuda*.dll`) and |
| `Unity.ML-Agents.Extensions*.dll` left over from an earlier generation of |
| those projects. They are inert here: |
| the shipped `Unity.ML-Agents.dll` references `Unity.InferenceEngine` only. |
| - No changes to the ML-Agents Python source are distributed in this repository. |
|
|
| Stock policies from `ml-agents-release_23`, redistributed unchanged under |
| Apache-2.0 (byte-identical to the upstream files): |
| - `Crawler.onnx` — `Crawler/TFModels/Crawler.onnx` |
| - `3DBallHard.onnx` — `3DBall/TFModels/3DBallHard.onnx` |
| - `PushBlock.onnx` — `PushBlock/TFModels/PushBlock.onnx` |
| - `Pyramids.onnx` — `Pyramids/TFModels/Pyramids.onnx` |
| - `Worm.onnx` — `Worm/TFModels/Worm.onnx` |
| - `Walker.onnx` — `Walker/TFModels/Walker.onnx` |
| - `DungeonEscape.onnx` — `DungeonEscape/TFModels/DungeonEscape.onnx` |
|
|
| Modified stock policies from `ml-agents-release_23`, redistributed under |
| Apache-2.0: |
| - `SoccerTwos.onnx` — `Soccer/TFModels/SoccerTwos.onnx` |
| - `tier_policies/PushBlock.onnx` — `PushBlock/TFModels/PushBlock.onnx` |
| - `tier_policies/Pyramids.onnx` — `Pyramids/TFModels/Pyramids.onnx` |
| - `tier_policies/DungeonEscape.onnx` — `DungeonEscape/TFModels/DungeonEscape.onnx` |
| - `tier_policies/SoccerTwos.onnx` — `Soccer/TFModels/SoccerTwos.onnx` |
|
|
| All upstream paths above are relative to |
| `Project/Assets/ML-Agents/Examples/` in the `ml-agents` repository. |
|
|
| -------------------------------------------------------------------------------- |
| Unity runtime components |
| `UnityPlayer.dll`, `UnityCrashHandler64.exe`, and the `MonoBleedingEdge/` |
| runtime are Unity Technologies components, redistributed here only as part of a |
| built player and subject to Unity Technologies' software terms, not the |
