Missing MUON Optimizer** +- **Issue**: `ImportError: cannot import name 'muon'` on line 27 of `reppo_alg/jaxrl/reppo.py` +- **Root cause**: Missing `muon.py` file in the repository +- **Fix applied**: Replaced all `muon.muon(lr)` calls with `optax.adam(lr)` as suggested in code comments + +**2. Hydra Configuration Issues** +- **Issue**: `Could not override 'env_name'` and `Could not override 'experiment_override'` +- **Root cause**: Incorrect Hydra parameter paths for environment and experiment configuration +- **Fix applied**: Use `env.name=` instead of `env_name=` and direct hyperparameter overrides instead of experiment_override + +**3. BraxGymnaxWrapper Method Signatures** +- **Issue**: `TypeError: BraxGymnaxWrapper.action_space() takes 1 positional argument but 2 were given` +- **Root cause**: Inconsistent method signatures between different environment wrappers +- **Fix applied**: Added optional `params=None` parameter to `action_space()` and `observation_space()` methods in BraxGymnaxWrapper + +**4. Training Loop Division by Zero** +- **Issue**: `ZeroDivisionError: integer division or modulo by zero` in training loop calculation +- **Root cause**: `eval_interval` calculated as 0 when `total_time_steps` is too small relative to batch size +- **Fix applied**: Increased minimum `total_time_steps` to 1,000,000 to ensure proper evaluation intervals + +**5. Incorrect Algorithm Name in Wandb** +- **Issue**: Wandb runs show name "resampling-sac-ant" instead of "reppo-*" +- **Root cause**: Config file incorrectly set `name: "sac"` instead of `name: "reppo"` +- **Fix applied**: Changed `name: "sac"` to `name: "reppo"` in `config/reppo.yaml` + +**6. JAX Key Batching Error** +- **Issue**: `ValueError: split accepts a single key, but was given a key array of shape (256, 2) != (). Use jax.vmap for batching.` +- **Root cause**: BraxGymnaxWrapper.reset() method doesn't handle batched keys from vmapped initialization +- **Fix applied**: Modified reset() method to detect and properly handle both single and batched keys using `jax.vmap` + +**Summary**: Fixed 6 critical bugs that prevented the original repository from running at all. The algorithm now works end-to-end with proper wandb integration. + --- ## Original README diff --git a/config/reppo.yaml b/config/reppo.yaml index aec3af7..f455b96 100644 --- a/config/reppo.yaml +++ b/config/reppo.yaml @@ -70,7 +70,7 @@ hyperparameters: measure_burnin: 3 -name: "sac" +name: "reppo" seed: 0 num_seeds: 1 tune: false diff --git a/reppo_alg/env_utils/jax_wrappers.py b/reppo_alg/env_utils/jax_wrappers.py index 0982307..4004ade 100644 --- a/reppo_alg/env_utils/jax_wrappers.py +++ b/reppo_alg/env_utils/jax_wrappers.py @@ -218,7 +218,11 @@ class BraxGymnaxWrapper: self.reward_scaling = reward_scaling def reset(self, key): -
