<|User|>You are an expert Python programmer. You will be given a question (problem specification) and will generate a correct Python program that matches the specification and passes all tests. ### Question: There are three cards with letters $\texttt{a}$, $\texttt{b}$, $\texttt{c}$ placed in a row in some order. You ...
There are three cards with letters $\texttt{a}$, $\texttt{b}$, $\texttt{c}$ placed in a row in some order. You can do the following operation at most once: - Pick two cards, and swap them. Is it possible that the row becomes $\texttt{abc}$ after the operation? Output "YES" if it is possible, and "NO" otherwise. ...

AReaL-boba-2-RL-Code Dataset

This dataset contains the training and testing data used for reinforcement learning in the AReaL-boba-2 model on coding tasks.

Dataset Structure

  • train/: Contains the training data for RL fine-tuning.
  • code_benchmark/: Contains the evaluation benchmark, organized into multiple subfolders, each corresponding to a specific coding benchmark suite, Codeforces, Code Contests and LiveCodeBench (v5) are supported now.

How to Use

To train and evaluate models using this dataset with AReaL:

  1. Download the dataset from this page.
  2. Train the model by following the AReaL training guideline.
  3. Prepare the evaluation data:
    • Move each subfolder inside code_benchmark/ to the evaluation/data/ directory in the AReaL repository.
  4. Run evaluation according to the AReaL evaluation guideline.
