Fine-Tuning LLMs: Generating JSONL Files with FragenAntwortLLMCPU
Introduction
Fine-tuning Large Language Models (LLMs) involves adapting a pre-trained model to perform specific tasks more effectively by providing additional training data. The "FragenAntwortLLMCPU"
is an inexpensive library that does not need a GPU to facilitate the initial step of fine-tuning the LLM process by generating question-answer (QA) sets in JSON format. "FragenAntwortLLMCPU"
uses only CPUs. This tutorial will guide you through the library's installation, setup, and usage to generate the JSONL files required for fine-tuning LLMs.
Prerequisites
Before you begin, ensure you have the following:
- Basic understanding of Python programming and LLMs.
Understanding LLMs and QA Sets
Large Language Models (LLMs)
LLMs, like Mistral, can understand and generate human-like text by being trained on vast amounts of data. Fine-tuning these models involves providing them with additional specific data to improve their performance on particular tasks, such as answering questions from documents, summarizing text, or engaging in dialogue.
Question-Answer (QA) Sets
QA sets are pairs of questions and answers derived from a text. They are crucial for training and fine-tuning LLMs to understand and respond to queries based on document content. Generating high-quality QA sets is critical in creating an effective fine-tuned model.
Installation
To install the FragenAntwortLLMCPU
Library, use the following pip command:
pip install FragenAntwortLLMCPU
This command will also install the necessary dependencies, such as PyMuPDF
, tokenizers
, semantic-text-splitter
, langchain
, and others.
Basic Usage
Step 1: Import the Library
First, import the necessary components from the library
from FragenAntwortLLMCPU import DocumentProcessor
Step 2: Initialize the Document Processor
Create an instance of the DocumentProcessor
Class with the required parameters:
pythdeprocessor = DocumentProcessor(
book_path="path/to/your/document/", # Directory path without ".pdf" term
temp_folder="path/to/temp/folder",
output_file="path/to/output/QA.jsonl",
book_name="YourDocument.pdf",
start_page=2,
end_page=4,
number_Q_A="one", # This should be a written number like "one", "two", etc.
target_information="specific information you need",
max_new_tokens=1000,
temperature=0.1,
context_length=2100,
max_tokens_chunk=400,
arbitrary_prompt=""
)
Explanation of Parameters
book_path
: Directory path to the document without the ".pdf" extension.temp_folder
: Path to a temporary folder for intermediate processing.output_file
: Path where the output JSONL file will be saved.book_name
: Name of the document file.start_page
: Starting page number for processing.end_page
: Ending page number for processing.number_Q_A
: Number of question-answer pairs to generate (as a written number).target_information
: Specific information you want to extract QA pairs from the document.max_new_tokens
: Maximum number of new tokens to generate.temperature
: the temperature rate (creativity) for the language model.context_length
: Maximum context length for the model.max_tokens_chunk
: Maximum number of tokens per chunk.arbitrary_prompt
: Any additional prompt you want to use.
Step 3: Load and Process the Document
Load the document and process it to extract text:
processor.process_book()
Step 4: Generate Prompts
Generate prompts from the processed text:
prompts = processor.generate_prompts()
print(prompts)
Step 5: Save the Prompts to a File
Save the generated prompts to a JSONL file:
processor.save_to_jsonl()
Full Example
Here’s a complete example of putting all the steps together:
from FragenAntwortLLMCPU import DocumentProcessor
# Initialize the processor
processor = DocumentProcessor(
book_path="path/to/your/document/",
temp_folder="path/to/temp/folder",
output_file="path/to/output/QA.jsonl",
book_name="YourDocument.pdf",
start_page=2,
end_page=4,
number_Q_A="one",
target_information="locations and foods",
max_new_tokens=1000,
temperature=0.1,
context_length=2100,
max_tokens_chunk=400,
arbitrary_prompt=""
)
# Process the document
processor.process_book()
# Generate prompts
prompts = processor.generate_prompts()
print(prompts)
# Save prompts to a JSONL file
processor.save_to_jsonl()
Advanced Usage
