Welcome to the world of SuperCorrect! In this blog post, we will walk you through implementing a novel two-stage fine-tuning method designed to enhance the reasoning accuracy and self-correction capabilities of Large Language Models (LLMs). Whether you’re a seasoned developer or a curious newcomer, this user-friendly guide will help you get started with this cutting-edge technology.
Understanding the Concept
Before we dive into the implementation, let’s clarify the analogy: imagine you are training a young student to solve math problems. Initially, they might solve problems using trial and error, which can lead to mistakes. However, by introducing a structured approach, like a step-by-step guide, they learn not only the correct answers but the reasoning behind them. SuperCorrect functions similarly by integrating a pre-defined hierarchical thought template called the Buffer of Thought (BoT) to guide LLMs through deliberate reasoning.
Quick Start
Requirements
- Ensure you have the transformers library version 4.37.0 or higher installed. This is essential since it includes the necessary code for Qwen2.5 models.
- Python installed on your machine.
- A compatible CUDA-enabled device for optimal performance.
Inference Setup
Follow the steps below to set up your inference environment easily:
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "BitStarWalkin/SuperCorrect-7B"
device = "cuda"
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype='auto',
device_map='auto'
)
tokenizer = AutoTokenizer.from_pretrained(model_name)
prompt = "Find the distance between the foci of the ellipse [9x^2 + frac{y^2}{29} = 99.]"
hierarchical_prompt = "Solve the following math problem in a step-by-step XML format. Each step should be enclosed within tags like ... . " \
"For each step enclosed within the tags, determine if this step is challenging. If so, provide annotations enclosed within ... ."
messages = [
{"role": "system", "content": hierarchical_prompt},
{"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
model_inputs = tokenizer([text], return_tensors='pt').to(device)
generated_ids = model.generate(**model_inputs, max_new_tokens=1024)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
Performance Evaluation
After implementing the SuperCorrect model, it’s time to evaluate its performance. The SuperCorrect-7B model has shown significant improvements on popular benchmarks such as GSM8K and MATH.
Troubleshooting Tips
- If your model does not load properly, double-check that you are using the correct version of the transformers library.
- Ensure that your CUDA device is set up correctly and is compatible with the installed packages.
