OceanWalker reproduction artifacts

This public dataset repository contains the large, versioned artifacts for the Morimorerain/OceanWalker code repository. Version v1 is intended for exact cache-only reproduction: the project can train and evaluate without Isaac Sim, rendering, or an external LLM API.

Archives

Archive Contents after extraction at the code-repository root Required for
oceansim-offline-data-v1.tar.zst datasets/haidi_instruction_expert/ and datasets/processed/ SFT and offline/cache evaluation
oceansim-observation-cache-v1.tar.zst scripts/haidi_expert_pipeline/observation_cache/ SFT and offline/cache evaluation
oceansim-isaac-assets-v1.tar.zst assets/OceanSim_assets/ Optional Isaac Sim rendering only

The cache archive intentionally excludes generated .lock files. It contains only the immutable observation data and metadata required by the code.

Download the two offline archives and RELEASE_SHA256SUMS.txt, verify them, then extract them from the root of a matching OceanWalker checkout:

hf download mourui/OceanWalker --repo-type dataset \
  oceansim-offline-data-v1.tar.zst \
  oceansim-observation-cache-v1.tar.zst \
  RELEASE_SHA256SUMS.txt \
  --local-dir .artifacts/oceanwalker-v1
cd .artifacts/oceanwalker-v1 && sha256sum -c RELEASE_SHA256SUMS.txt && cd ../..
tar --use-compress-program=unzstd -xf .artifacts/oceanwalker-v1/oceansim-offline-data-v1.tar.zst
tar --use-compress-program=unzstd -xf .artifacts/oceanwalker-v1/oceansim-observation-cache-v1.tar.zst

The base model is intentionally not mirrored here. Obtain the expected revision from Qwen/Qwen2.5-VL-7B-Instruct under models/Qwen2.5-VL-7B-Instruct/.

See the code repository README for installation, path configuration, streaming and legacy protocols, training, evaluation, and optional simulator setup.

Data use

These files are released solely as the reproduction artifacts accompanying OceanWalker. They include derived observations and third-party scene assets. Users are responsible for complying with the upstream OceanSim, NVIDIA/Isaac Sim, Qwen, and individual asset licenses before redistribution or commercial use.
