Version-aware guidance for PufferLib reinforcement-learning environments, vectorization, policies, PuffeRL training, evaluation, and safe checkpoint review. Covers the native 5.0 build and environment API, published 3.0.0 Gymnasium/PettingZoo adaptation, and a pinned historical 4.0 profile.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PufferLib Choose the version before choosing an API. Reviewed **2026-10-01**: | Profile | Status | Main use | |---|---|---| | Native source `5.0` | Current default branch and live documentation | C/CUDA environments, native trainer; CPU evaluation only | | `pufferlib==3.0.0` | Latest PyPI release, published 2025-06-23; sdist only | Python/Gymnasium/PettingZoo adaptation and Torch PuffeRL | | Pinned source `4.0` | Historical snapshot | C Ocean interface with an optional Torch fallback | For **5.0**, read [references/native-5.md](references/native-5.md). The reviewed revision is `6ffa5b10dbbbe4d1e8288367c7d9d3acd3bad4a2`. Its CLI is `./puffer train` after building an environment, not `puffer train ENV_NAME`. There is no 5.0 Python emulation/vector API or `--slowly` fallback. The bundled plan schema deliberately supports only 3.0 and pinned 4.0; it does not launch training. All native/PufferLib training examples are **source-reviewed, illustrative, and not executed in this review**. Bundled synthetic checks are executed CPU tests, not evidence of PufferLib installation or learning quality. The PyPI sdist was hash-verified and its Python sources inspected; the moving …

How to install
mdr add k-dense-ai/scientific-agent-skills/pufferlib@sha256:031975c6abaabd82The line at the top of this page pins the label v1.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
