Configuration FAQ

Why does it fail even though I set policy_path?​

  1. Verify the file exists
  2. Confirm it's not an old 1402D / TWIST2 ONNX model
  3. Confirm the input dimension is 166 with dual inputs (obs + obs_history)

Why must I specify input.bvh_file explicitly?​

input/bvh.yaml no longer provides machine-specific default paths. Always specify explicitly:

python scripts/run/run_sim.py \
    controller.policy_path=policy.onnx \
    input.bvh_file=data/sample_bvh/aiming1_subject1.bvh

Why doesn't viewer=true work?​

The legacy viewer alias has been removed. Use viewers (plural):

python scripts/run/run_sim.py controller.policy_path=policy.onnx viewers=sim2sim
python scripts/run/run_sim.py controller.policy_path=policy.onnx viewers=none
