Fine-tuning machine learning models requires well-prepared datasets. The guide outlines the process of creating these datasets, from gathering data to making instruction files. It emphasizes the importance of having a comprehensive and efficient data collection process, using methods such as web scraping, extracting documents from Confluence, and retrieving relevant files from Git repositories. The guide also covers text content extraction using libraries like BeautifulSoup and PyPDF2, generating instructions using functions like `generate_content()` and `generate_instructions()`, and loading and saving domain knowledge. Additionally, it provides a main function that coordinates dataset generation, including querying Ollama's Llama 2 model to get model answers and follow-up questions, formatting results in JSONL format, and creating train, test, and validation files. The guide concludes by emphasizing the importance of refining machine learning models like Mistral 7B with Ollama's Llama 2 and providing tools to develop datasets that optimize performance and accuracy for advanced applications.
