next to `pretrained_model/`. Replace the pickled `training_state.pt`
with an enriched `training_step.json` carrying `step` and
`interaction_step`, so resume restores actor + critics + target nets +
temperature + optimizers + RNG + counters from HF-standard files.

If VideoDecoder() raises during initialization, the fsspec file handle
was leaked since it was opened via __enter__() but never closed on the
exception path. Now explicitly closes the handle before re-raising.
* chore(deps): allow torch 2.11/2.12 and fix autocast deprecation
- Bump torch to >=2.7,<2.13 (was <2.11), torchvision to <0.28 (was <0.26),
and torchcodec to <0.13 (was <0.11) to allow installs against the latest
stable torch 2.11 and the upcoming 2.12 line.
- Replace removed torch.get_autocast_gpu_dtype() with torch.get_autocast_dtype("cuda")
in Florence2 and Qwen2.5-VL-MoE FlashAttention paths (the former is removed in 2.11+).
- Refresh uv.lock for the new resolution (torch 2.11.0+cu130, torchvision 0.26.0+cu130,
torchcodec 0.11.1, full CUDA 13 stack).
Verified locally with `uv sync --locked` from a clean .venv and the lerobot
test suite (pytest -n 8 --dist=loadfile --timeout=300). Failure set is
identical to the pre-bump baseline: 18 pre-existing failures
(test_sac_policy*, test_pi0_rtc*, test_pi05_rtc*, test_replay_buffer*),
0 new, 0 fixed.
AI assistance: this change was authored with Claude Code per AI_POLICY.md.
* fix(policies): use device-agnostic autocast dtype lookup
Pass query_states.device.type to torch.get_autocast_dtype() instead of
hardcoding 'cuda', so the cast matches the active autocast context when
running under CPU/MPS/XPU autocast.

* fix(train): restrict legacy RA-BC migration to JSON checkpoints only
_migrate_legacy_rabc_fields was called for all config files, causing
json.load to raise DecodeError when a YAML/TOML config was passed to
lerobot-train for a new training run. Guard the block with an
.endswith(".json") check so migration only runs when resuming from
a JSON checkpoint.
* fix(ci): run multi-task benchmark evals 5-at-a-time in parallel
The eval script supports running tasks concurrently via a
ThreadPoolExecutor (env.max_parallel_tasks). Apply it to the four
multi-task benchmark CI jobs (RoboTwin, RoboCasa, RoboMME, LIBERO-plus
— 8-10 tasks/task_ids each) so they finish in ~2 waves of 5 instead of
running sequentially. Single-task jobs (Libero, MetaWorld, RoboCerebra)
are unchanged.
* fix(ci): cap VLABench smoke eval at 50 steps per task
VLABench's default episode_length is 500 steps; with 10 tasks at ~1 it/s
the smoke eval took ~80 minutes of rollouts on top of the image build.
The eval is a pipeline smoke test (running_success_rate stays at 0% on
this short rollout anyway), so we don't need full episodes — cap each
task at 50 steps to bring total rollout time down ~10x.
* fix(ci): run VLABench tasks 5-at-a-time in parallel
The eval script already supports running multiple tasks concurrently via
a ThreadPoolExecutor (env.max_parallel_tasks). Set it to 5 so the 10
VLABench tasks finish in ~2 waves instead of running sequentially.
* feat: add pretrained vision encoder weights for diffusion and vqbet

The robotwin benchmark Dockerfile still installed cuda-nvcc-12-4 and
cuda-cudart-dev-12-4 after #3505 upgraded the base image to CUDA 12.6.3
on Ubuntu 24.04. Those packages aren't available in the ubuntu2404 CUDA
repo, so the build failed at apt-get install. Bumping both to -12-6 to
match the base image.
* feat(policies): add EO-1 model
* chore(eo1): adjust policy_eo1_README.md to to avoid duplicate with eo1.mdx
* chore(eo1): remove policy_eo1_README.md, link eo1.mdx in policy folder

Move PI0 and PI0.5 noise/time sampling into the policy wrappers so the compiled PyTorch cores receive them as tensor inputs.
This keeps Beta sampling out of torch.compile on MPS, avoiding aten::_sample_dirichlet compilation errors while preserving the CUDA training path.
