# RLinf

[RLinf](https://github.com/RLinf/RLinf) is an open-source framework for Reinforcement Learning training, focused on supporting the reinforcement learning training of large language models (LLMs) and vision-language models (VLAs). RLinf provides advanced features such as unified programming interfaces, flexible execution modes, automatic scheduling, and elastic communication, supporting various reinforcement learning algorithms like PPO and GRPO.

RLinf supports real-time experiment tracking, allowing you to stream loss curves, accuracy, GPU utilization, and any custom metrics to **SwanLab**.

You can use RLinf to quickly conduct reinforcement learning model training while using SwanLab for experiment tracking and visualization.

## Quick Integration with SwanLab

RLinf supports enabling SwanLab as a logging backend in the YAML configuration file. Simply add `"swanlab"` to the `runner.logger.logger_backends` in the configuration file.

Add the following configuration to your YAML configuration file:

```yaml
runner:
  task_type: math # or "embodied", etc.
  logger:
    log_path: ${runner.output_dir}/${runner.experiment_name}
    project_name: rlinf
    experiment_name: ${runner.experiment_name}
    logger_backends: ["swanlab"] # [!code ++]
  experiment_name: grpo-1.5b
  output_dir: ./logs
```

After running the training, RLinf will create a subdirectory for the enabled SwanLab backend:

```
logs/grpo-1.5b/
├── checkpoints/
├── converted_ckpts/
├── log/
├── swanlab/            # SwanLab runtime directory
```

## Setting Project Name and Experiment Name

You can set the project name and experiment name by configuring `project_name` and `experiment_name` in the YAML configuration file:

```yaml
runner:
  project_name: rlinf
  experiment_name: grpo-1.5b
```

## Setting Log File Save Location

You can set the log file save location by configuring `log_path` in the YAML configuration file:

```yaml
runner:
  log_path: ./logs
```
