PufferLib
Use PufferLib with an explicit version profile. Upstream currently has two incompatible surfaces:
| Profile | Status on 2026-07-23 | Main use |
|---|---|---|
pufferlib==3.0.0 |
Latest stable PyPI release, published 2025-06-23 | Python/Gymnasium/PettingZoo emulation, pufferlib.vector, Torch PuffeRL |
source 4.0 |
Upstream default branch; not the latest stable PyPI artifact | Native C Ocean environments, native CUDA trainer, optional Torch fallback |
Do not combine 3.0 imports with 4.0 config/CLI examples. The 4.0 redesign
removed the 3.0 emulation, vector, and pytorch modules from the current
package tree.
