FAQPage Schema
How do I set up reinforcement learning training with GRPO using Parquet data?

To set up GRPO training, you need to enforce strict Parquet data formatting and apply ready-to-use templates. This automates the reinforcement learning setup and policy optimization tasks for reproducible configurations.

What is the best way to prepare data for SFT on GSM8K-style datasets?

The best way to prepare data for SFT is by using Parquet-based data templates. This enforces strict data formatting and simplifies the data preparation workflow for Supervised Fine-Tuning tasks.

Do I need strict Parquet formatting for reinforcement learning experiments?

Yes, you need strict Parquet formatting for reinforcement learning experiments to ensure reproducibility. This structured approach enforces data formatting standards and provides ready-to-use templates for training pipelines.

Can I use these templates for end-to-end SFT and GRPO pipelines?

Yes, you can use these templates for end-to-end SFT and GRPO pipelines. They enable complete reinforcement learning training workflows with reproducible configurations from installation through data preparation and execution.

Why does my reinforcement learning setup require ready-to-use templates?

Your reinforcement learning setup requires ready-to-use templates to enforce strict data formatting and simplify installation. This structured approach ensures reproducible configurations across complex training workflows.
