Third-party notices

The project license does not replace the licenses of its dependencies or copied
upstream material. The dependency versions below reflect the current uv.lock.
Packages are installed separately; their complete license and copyright notices
remain in their distributions. This table summarizes the main runtime packages,
not every transitive dependency or platform-specific binary component.
| Package | Version | Declared license | Upstream |
|---|---|---|---|
| ale-py | 0.11.2 | GPL-2.0-only | Arcade Learning Environment |
| gymnasium | 1.3.0 | MIT | Gymnasium |
| numpy | 2.5.3 | BSD-3-Clause AND 0BSD AND MIT AND Zlib AND CC0-1.0 | NumPy |
| httpx | 0.28.1 | BSD-3-Clause | HTTPX |
| imageio | 2.37.4 | BSD-2-Clause | ImageIO |
| imageio-ffmpeg | 0.6.0 | BSD-2-Clause (Python wrapper) | imageio-ffmpeg |
The imageio-ffmpeg wrapper's license does not describe all rights or obligations
for the FFmpeg executable it invokes or distributes. FFmpeg licensing depends on
the build; preserve the relevant binary distribution's notices when redistributing
it. See FFmpeg licensing.
Atari game ROMs and game audiovisual content retain their respective owners' rights. They are not relicensed by this project. Jev is an external service, not a model implementation or set of weights distributed under the project license.
OCAtari-derived Pong object extraction
The Pong RAM mapping and vision color definitions in src/jev_atari/observation.py
are adapted from OCAtari at revision
99c874675df6b76a33a80b57776c123fbcd051af:
- https://github.com/k4ntz/OC_Atari/blob/99c874675df6b76a33a80b57776c123fbcd051af/ocatari/ram/pong.py
- https://github.com/k4ntz/OC_Atari/blob/99c874675df6b76a33a80b57776c123fbcd051af/ocatari/vision/pong.py
The full OCAtari package is not installed. The extraction is Pong-specific, fixed, and supplies semantic object observations, not a general learned visual encoder.
