* [Trainer] Support per-token rewards in trainer (NovaSky-AI#109) * Add check for whether p2p access is supported - allows code to run on L4/L40S after NovaSky-AI#73 upgrade to cuda 12.8 (NovaSky-AI#108) # Overview After NovaSky-AI#73, the main code path no longer runs on GPUs without P2P support (potentially due to cuda 12.8 upgrade?) - an error would be thrown like ```bash torch.distributed.DistBackendError: NCCL error in: /pytorch/torch/csrc/distributed/c10d/ProcessGroupNCCL.cpp:3353, unhandled cuda error (run with NCCL_DEBUG=INFO for details), NCCL version 2.26.2 ncclUnhandledCudaError: Call to CUDA function failed. Last error: Cuda failure 217 'peer access is not supported between these two devices' ``` This PR adds a check for whether peer access is supported (using torch/cuda) between all GPUs on a node to the ray initialization, and sets relevant NCCL env vars to allow the code to run on these machine types. ```python if not peer_access_supported(): logger.info("Peer access is not supported, disabling P2P and SHM") env_vars["NCCL_P2P_DISABLE"] = "1" env_vars["NCCL_SHM_DISABLE"] = "1" ``` Example running on L40S: <img width="1854" height="227" alt="image" src="https://github.com/user-attachments/assets/1cca46b5-6e16-4ae7-9a33-df52d138bdeb" /> * [dependencies] Upgrade ray to 2.48.0 (NovaSky-AI#106) # What does this PR do Upgrades ray to 2.48.0, which allows us to remove the pip install vllm in the Dockerfile as a fallback for when uv + vllm does not resolve dependencies with the vllm + ray backend correctly. We leave the previous Dockerfile in `docker/Dockerfile.ray244` for backwards compatibility --------- Co-authored-by: Sumanth R Hegde <[email protected]> * fix issue with NovaSky-AI#108 that broke gpu ci (NovaSky-AI#112) missed an argument in `gpu_ci/conftest.py` for `peer_access_supported()` - fix for gpu ci to run Passing now with update: <img width="1811" height="861" alt="image" src="https://github.com/user-attachments/assets/70011c54-1e33-44b5-83a0-616029f891d2" /> And main runs (and disables p2p access) correctly: <img width="2067" height="203" alt="image" src="https://github.com/user-attachments/assets/399aff67-cc51-4588-a632-47698073593c" /> * Add warning for certain uv versions due to `uv run --with` regression (NovaSky-AI#113) # What does this PR do? Adds a warning for uv versions 0.8.0, 0.8.1 and 0.8.2 due to a bug in the uv run --with flag for "Running in ray cluster" section. These are relatively new versions and thus it's better to have this detail in the documentation for users. <img width="692" height="458" alt="Screenshot 2025-07-25 at 6 09 15 PM" src="https://github.com/user-attachments/assets/f1997eac-2867-4552-8ef7-eea8741e32b6" /> <img width="779" height="568" alt="Screenshot 2025-07-25 at 6 09 19 PM" src="https://github.com/user-attachments/assets/5080d328-c934-4864-91a8-932902dea934" /> --------- Signed-off-by: SumanthRH <[email protected]> * [GPU CI] Only trigger workflow for relevant changes in `skyrl-train` (NovaSky-AI#114) * [bug] Loading saved HF weights errors (NovaSky-AI#118) Addresses NovaSky-AI#97 * [DAPO] Add support for overlong filtering (NovaSky-AI#111) ## What does this PR do? Adds `apply_overlong_filtering` to the generator config, and provides a generator utility method `apply_overlong_filtering()` for post-processing the loss mask. I originally implemented this using the `stop_reasons` to determine whether the sequence was truncated, but instead switched to looking for `eos_token` in the response IDs for a more general approach. ## Tests Added CPU tests for the utility method and for SkyRL Gym Generator's use of the utility method. * [skyrl-gym] GSM8k - LLM Judge example (NovaSky-AI#74) * Fix MLFlow logging (NovaSky-AI#121) This is a small change to make the MLFlow integration work. Currently this fails with a Pandas error when trying to flatten an Omega dict; we need to convert to a regular Python dictionary. Can confirm this works on our MLFlow setup: <img width="1406" height="683" alt="image" src="https://github.com/user-attachments/assets/fcee526a-815e-4f08-bf25-d2709779ced7" /> * [Trainer] Support registering custom advantage estimators (NovaSky-AI#115) ## What does this PR do? Adds an `AdvantageEstimatorRegistry` to support custom advantage estimation methods without modifying the skyrl-train package. Added `examples/algorithm/custom_advantage_estimator` folder to give quick example of how to register a custom adv est function. ## Tests Adding cpu test to ensure registration works. * [checkpointing] Add HF model config and tokenizer config to checkpoint folder (NovaSky-AI#124) # Overview Adds the HF model config and tokenizer config to `ckpt_path/huggingface` for deepspeed and fsdp. So now the checkpoint directory will be: ``` {ckpt_path}/ ├── latest_ckpt_global_step.txt # Holds the global step of the latest checkpoint ├── global_step_10/ # Checkpoint at training step 10 │ ├── policy/ # Policy model checkpoint directory │ │ ├── fsdp_config.json # stores fsdp version and world size │ │ ├── huggingface/ │ │ ├── config.json # model config │ │ ├── tokenizer_config.json # tokenizer config │ │ ├── generation_config.json # generation config │ │ ├── ... # other tokenizer config files │ │ ├── model_state.pt # Model parameters │ │ ├── optimizer_state.pt # Optimizer state │ │ └── lr_scheduler_state.pt # Learning rate scheduler state ``` For deepspeed it will be similar but without `fsdp_config.json` ``` {ckpt_path}/ ├── latest_ckpt_global_step.txt # Holds the global step of the latest checkpoint ├── global_step_10/ # Checkpoint at training step 10 │ ├── policy/ # Policy model checkpoint directory │ │ ├── huggingface/ │ │ ├── config.json # model config │ │ ├── tokenizer_config.json # tokenizer config │ │ ├── generation_config.json # generation config │ │ ├── ... # other tokenizer config files │ │ ├── ... # deepspeed checkpointing files ``` * Fix discord link (NovaSky-AI#125) * Fix broken link (NovaSky-AI#128) * [Trainer/Algorithm] Support registering custom policy loss functions + refactor adv estimator registry to allow registration outside ray workers (NovaSky-AI#126) # Overview - Adds support for registering custom policy loss functions, similar to NovaSky-AI#115, - Refactors the policy loss to be a function in `ppo_utils.py` instead of a (`nn.Module` in `worker.py`) - Introduces a breaking change in renaming `trainer.algorithm.ppo_loss_type` to `trainer.algorithm.policy_loss_type` - Addresses Issue NovaSky-AI#116 by creating a new `BaseFunctionRegistry` class that uses a [named actor](https://docs.ray.io/en/latest/ray-core/actors/named-actors.html) to support the following pattern: ```python # Example of custom policy loss: "simple_baseline" def compute_simple_baseline_policy_loss( log_probs: torch.Tensor, ... ): return torch.randn(1, device=log_probs.device), 0.0 # Register the custom policy loss - outside of the ray worker PolicyLossRegistry.register("simple_baseline", compute_simple_baseline_policy_loss) @ray.remote(num_cpus=1) def skyrl_entrypoint(cfg: DictConfig): exp = BasePPOExp(cfg) exp.run() @hydra.main(config_path=config_dir, config_name="ppo_base_config", version_base=None) def main(cfg: DictConfig) -> None: # validate the arguments validate_cfg(cfg) initialize_ray(cfg) ray.get(skyrl_entrypoint.remote(cfg)) ``` this change was necessary for `PolicyLossRegistry` to be accessible, since the worker `actor_loss_fn` attribute is set in `init_model` within the `worker` actor, which is a ray actor created from within the skyrl_entrypoint ray task (and registering within the entrypoint wouldn't propagate down another layer). - updates AdvantageEstimatorRegistry to extend the same `BaseFunctionRegistry` class Example runs: Custom advantage (mean of reward) <img width="956" height="326" alt="image" src="https://github.com/user-attachments/assets/1b7222bc-fbb9-49b1-876d-265b71201087" /> Custom policy loss (reinforce - just (-logprobs * advantages).mean()) <img width="939" height="330" alt="image" src="https://github.com/user-attachments/assets/cbed7ef5-b3e7-4e32-beba-b52b80879f47" /> * [SkyAgent] Upload initial refactored code (NovaSky-AI#131) # What does this PR do? Uploading our initial refactored code for SkyAgent --------- Signed-off-by: SumanthRH <[email protected]> Co-authored-by: Shiyi Cao <[email protected]> Co-authored-by: Dacheng Li <[email protected]> * [trainer] add more robust generation output validation (NovaSky-AI#132) # Overview Adds a `validate_generation_output` function in `trainer_utils.py` with more robust validation of generation output format. Specifically, given ``` class GeneratorOutput(TypedDict): prompt_token_ids: List[List[int]] response_ids: List[List[int]] rewards: Union[List[float], List[List[float]]] loss_masks: List[List[int]] stop_reasons: Optional[List[str]] rollout_metrics: Optional[Dict[str, Any]] ``` We expect - all list attributes should have the same length and be the same length as the input batch of prompts at dim=0 - non zero length lists - response_ids, loss masks, and rewards (if token level rewards) should be the same length - the sum of loss masks should be non-zero (logging a warning if it is not) verified gsm8k run still works: <img width="563" height="330" alt="image" src="https://github.com/user-attachments/assets/eeefebcb-d5fc-486d-b906-f4344b1e2779" /> --------- Co-authored-by: Sumanth R Hegde <[email protected]> * [Trainer] GSPO support (NovaSky-AI#120) This PR adds support for [Group Sequence Policy Optimization (GSPO)](https://arxiv.org/abs/2507.18071), the hotness du jour from Alibaba Qwen. The implementation in this PR is loosely based on [this one](huggingface/trl#3775) from TRL. It adds an `importance_sampling_level` config option which can be `token` (PPO/GRPO) or `sequence` (GSPO). I ran a short/small GSM8k run with Qwen2.5-0.5B and the loss curves look okay: <img width="314" height="240" alt="image" src="https://github.com/user-attachments/assets/f52d7c64-416c-4419-aa96-4a03c9048007" /> However, I had to hack a few things to get this to run on Datadog's cloud infra (including changing some dependency versions) so I'd encourage one of the maintainers to reproduce these results locally before merging. * [SkyAgent] Add initial docs (NovaSky-AI#134) # What does this PR do? Adds initial documentation for SkyAgent. We are still actively cleaning this package up, but I thought initial documentation will be helpful for anyone who stumbles across this. The documentation folder is still in `skyrl-train`, and much of the docs also refer to "SkyRL" when they are really referring to "SkyRL-train", so to avoid any confusion, I have just added this as a simple page on the sidebar. We need to make the docs be mono-repo wide and structure it better but I'm leaving it for a future PR. --------- Signed-off-by: SumanthRH <[email protected]> * [trainer/algorithm] Implement DAPO and Polaris style dynamic sampling + add DAPO docs + example (NovaSky-AI#130) # Overview This PR introduces filter (DAPO) and replace (Polaris/WebSailor) style dynamic sampling strategies. The dynamic sampling strategy can be configured as below: ```yaml # dynamic sampling parameters dynamic_sampling: type: null # filter (DAPO), replace (POLARIS/WebSailor), or null max_sample_batches: 30 # sample at most this many batches before stopping, -1 to sample forever min_replace_ratio: 0.3 # minimum proportion of good samples with which to replace bad samples (for replace strategy only) ``` This PR also adds a docs page describing how to enable all DAPO features, and adds an example GSM8K script where all these features are used. ## Minor Changes Some minor changes to make this dynamic sampling implementation clean: - the utils `Timer` class now updates the dict instead of overwriting in order to correctly track generation time w/ dynamic sampling, which means we need to make sure to reset `all_timings` in any trainer - The use of `self.weights_manager` is a little tricky for the dynamic sampling - introduced the the `ConditionalWeightsManager` to make the added code in the training loop as clean as possible ## Example runs <img width="413" height="264" alt="image" src="https://github.com/user-attachments/assets/072f716a-3632-42bb-a5f7-5f9d6064bd93" /> Generation time for dapo style filtering increases as the training run goes on, while it is stable for polaris and the baseline. <img width="419" height="265" alt="image" src="https://github.com/user-attachments/assets/887df550-e4b9-4623-b578-b4809a9f403f" /> We can see that the training pass @ n metric is 1 for both polaris and dapo style filtering as expected. <img width="421" height="259" alt="image" src="https://github.com/user-attachments/assets/bb63af77-1fbb-4d89-9216-b028f1551ea7" /> For GSM8k + Qwen 1.5B, the sampling strategy (as well as the full DAPO run) results in minimal gains - need larger models/harder dataset to test more fully DAPO sampling Example Run: ```bash (skyrl_entrypoint pid=222117) 2025-08-04 23:13:13.439 | INFO | skyrl_train.trainer:train:245 - Started: 'step' (skyrl_entrypoint pid=222117) 2025-08-04 23:13:13.737 | INFO | skyrl_train.weights_manager:__enter__:76 - Started: 'sync_weights_to_inference_engines' (skyrl_entrypoint pid=222117) 2025-08-04 23:13:16.401 | INFO | skyrl_train.weights_manager:__enter__:76 - Finished: 'sync_weights_to_inference_engines', time cost: 2.66s (skyrl_entrypoint pid=222117) 2025-08-04 23:13:16.401 | INFO | skyrl_train.weights_manager:__enter__:80 - Started: 'offload_policy_model_to_cpu' (skyrl_entrypoint pid=222117) 2025-08-04 23:13:16.842 | INFO | skyrl_train.weights_manager:__enter__:80 - Finished: 'offload_policy_model_to_cpu', time cost: 0.44s (skyrl_entrypoint pid=222117) 2025-08-04 23:13:16.888 | INFO | skyrl_train.trainer:train:261 - Started: 'generate' (AsyncVLLMInferenceEngine pid=223856) INFO 08-04 23:13:13 [executor_base.py:227] It took 0.243244 seconds to wake up tags ['weights'].
