From 22807cc457c55e3ee9077cb6cda9c434e750eb38 Mon Sep 17 00:00:00 2001 From: tatp-yf Date: Tue, 17 Mar 2026 23:10:31 +0800 Subject: [PATCH 1/7] feat: replace ml_collections with dataclass + Hydra config system - Add structured_configs.py with typed dataclasses (SACConfig, TD3Config, APPOConfig, PPOConfig) - Create conf/ directory with 18 YAML files for offpolicy/appo/ppo configs - Rewrite all 4 training scripts to use @hydra.main() instead of argparse - Strip locomotion_params.py and manipulation_params.py to KNOWN_TASKS only - Remove ConfigDict compat code from appo/runner.py - Update all tests to use structured configs and Hydra composition - Replace ml_collections with hydra-core>=1.3 in pyproject.toml - Fix play_interactive.py and benchmark_fast_sac_backends.py Benefits: - Type-safe configs with IDE autocomplete - YAML-based config management with version control - CLI override support (e.g., algo.num_envs=2048) - Flexible task/algo composition via Hydra defaults All 106 tests pass. --- benchmark/benchmark_fast_sac_backends.py | 17 +- conf/appo/config.yaml | 64 +++++ conf/appo/task/g1_joystick.yaml | 6 + conf/appo/task/go1_joystick.yaml | 3 + conf/appo/task/go2_joystick.yaml | 3 + conf/offpolicy/algo/sac.yaml | 28 ++ conf/offpolicy/algo/td3.yaml | 32 +++ conf/offpolicy/config.yaml | 29 ++ conf/offpolicy/task/allegro_sac.yaml | 16 ++ conf/offpolicy/task/g1_sac.yaml | 12 + conf/offpolicy/task/go1_joystick.yaml | 6 + conf/offpolicy/task/go2_joystick.yaml | 5 + conf/ppo/config.yaml | 79 +++++ conf/ppo/config_mlx.yaml | 71 +++++ conf/ppo/task/allegro_inhand.yaml | 11 + conf/ppo/task/g1_joystick.yaml | 11 + conf/ppo/task/g1_motion_tracking.yaml | 14 + conf/ppo/task/go1_joystick.yaml | 10 + conf/ppo/task/go2_joystick.yaml | 9 + pyproject.toml | 2 +- scripts/play_interactive.py | 4 +- scripts/train_appo.py | 181 +++++------- scripts/train_mlx_ppo.py | 168 ++++------- scripts/train_offpolicy.py | 333 +++++++++------------ scripts/train_rsl_rl.py | 290 ++++++------------- src/unilab/algos/torch/appo/runner.py | 5 -
