MLWizards

MLWizards is a Python library designed to simplify the process of creating chatbots and fine-tuning models using OpenAI. It also includes features for extracting and processing text from PDFs.

Features

• ChatBot: Easily create and interact with chatbots using OpenAI's GPT models.
• Model Fine-Tuning: Fine-tune OpenAI models with your own data.
• PDF Text Extraction: Extract and preprocess text from PDF files using OCR.

Installation

1. Install the required Python packages:

pip install pytesseract pdf2image pillow requests-html openai beautifulsoup4

2. Install Poppler:

Windows

• Download Poppler from here.
• Extract the contents to a directory, e.g., C:\poppler.
• Add C:\poppler\bin to your system's PATH.

macOS

• Use Homebrew to install Poppler:

  brew install poppler

Linux

• Use the package manager to install Poppler:

  sudo apt-get install poppler-utils

3. Install Tesseract OCR:
   • Follow the instructions here to install Tesseract OCR on your operating system.

Usage

ChatBot

Create and interact with a chatbot using OpenAI's GPT models.

from mlwizards import ChatBot

api_key = "your_openai_api_key"
bot = ChatBot(api_key=api_key)

while True:
    user_input = input("You: ")
    if user_input.lower() in ['exit', 'quit']:
        break
    response = bot.generate(user_input)
    bot.add_to_history('user', user_input)
    bot.add_to_history('assistant', response)
    print("Bot:", response)

Model Fine-Tuning

Fine-tune OpenAI models with your own data.

from mlwizards import fine_tune_model, upload_file

api_key = "your_openai_api_key"
training_file_path = "path/to/your/training_data.jsonl"

# Upload the training file
upload_response = upload_file(api_key, training_file_path)
training_file_id = upload_response['id']

# Fine-tune the model
fine_tune_response = fine_tune_model(api_key, training_file_id)
print(f"Fine-tuning job started. Response: {fine_tune_response}")

PDF Text Extraction

Extract and preprocess text from PDF files using OCR.

from mlwizards import extract_text_from_pdf

pdf_path = "path/to/your/file.pdf"
tesseract_cmd = "/usr/local/bin/tesseract"  # Update this path to your tesseract executable if needed
extracted_text = extract_text_from_pdf(pdf_path, tesseract_cmd)
print(extracted_text)

Functions

ChatBot Class

• __init__(self, api_key, model='gpt-3.5-turbo', organization=None, project=None): Initialize the ChatBot with API key and model.
• generate(self, prompt): Generate a response from the chatbot.
• add_to_history(self, role, content): Add a message to the conversation history.
• reset_conversation(self): Reset the conversation history.
• search_internet(self, query, num_results=5): Search the internet and generate a response based on search results.

Fine-Tuning Functions

• fine_tune_model(api_key, training_file_id, model='gpt-3.5-turbo', organization=None, project=None, suffix=None, hyperparameters=None): Fine-tune a model with the given training file.
• upload_file(api_key, file_path, purpose='fine-tune', organization=None, project=None): Upload a file to OpenAI.

PDF Text Extraction Functions

• extract_text_from_pdf(pdf_path, tesseract_cmd=None): Extract text from a PDF file using OCR.
• preprocess_text(text): Preprocess extracted text by removing unnecessary whitespace and newlines.
