Installing a Local Language Model on Apple Silicon Mac M1 or M2 Max

Introduction

In this tutorial, we will guide You through the process of installing a local language model on an Apple Silicon Mac machine, specifically the M1 or M2 Max. Language models such as Chat GPT have gained popularity, and there are several open-source models available, including Facebook's Llama and Falcon. We will be using a project called Lamma.cpp, which supports local installation of large language models. Let's get started!

Installing Homebrew on Mac

To begin, we need to install Homebrew on your Mac. Homebrew is a Package manager for macOS that allows us to easily install and manage software packages. Follow these steps to install Homebrew:

  1. Open the Terminal on your Mac.
  2. Run the following command: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  3. Press Enter and follow the instructions to complete the installation.

Installing Required Packages

Now that Homebrew is installed, we need to install the required packages for the Lamma.cpp project. Execute the following commands in the Terminal:

  1. brew install gcc@9 llvm cmake boost
  2. brew install nano tree

Cloning Lama.cpp Project

Next, we will clone the Lamma.cpp project into your Mac. This project is hosted on GitHub and provides support for installing local language models. Follow these steps:

  1. Open the Terminal on your Mac.
  2. Navigate to the folder where you want to clone the project using the cd command.
  3. Run the following command: git clone https://github.com/facebookresearch/lama.cpp.git

Downloading the Lamma Model

Now, let's download the Lamma model for our local installation. The Lamma model was initially released by Facebook for researchers, but the weights have been leaked, leading to multiple implementations of open Lamma-like models. We will be using the popular model available on Hugging Face. Follow these steps:

  1. Visit huggingface.co in your web browser.
  2. Search for the Lamma model.
  3. Click on the most popular model among users.
  4. Inside the "Files and Versions" section, locate the PyTorch model files.
  5. Download all 33 PyTorch model files, as well as the "special_tokens_map.json" and "tokenizer.model" files.

Moving Files to the Project Folder

Once you have downloaded the necessary files, let's move them to the project folder. Follow these steps:

  1. Open the Finder on your Mac.
  2. Navigate to the cloned "lama.cpp" project folder.
  3. Create a folder named "7b" inside the "models" folder.
  4. Move all the downloaded files into the newly created "7b" folder.

Setting Up Python 3.10 and Virtual Environment

Now, let's ensure we have Python 3.10 and set up a virtual environment for our project. Execute the following commands in the Terminal:

  1. Check your Python version by running: python --version
    • If you have Python 3.10 installed, proceed to the next step.
    • If you don't have Python 3.10, you can install it using Homebrew with the command: brew install python@3.10
  2. Create a virtual environment by running: python3.10 -m venv venv
  3. Activate the virtual environment: source venv/bin/activate

Converting Model Files to GDML Format

To prepare the model files for our project, we need to convert them to the GDML format. Execute the following command in the Terminal:

  • cd models/7b && python3.10 ../conv.py --model=ddgpt

Quantizing the Model to 4-bit

Quantization is a technique that reduces the precision of model weights, making the models faster and smaller. Let's quantize the model to 4-bit using the following command:

  • ./quantize.sh

Testing the Model

Now, let's test if the model is working properly. Execute the following command in the Terminal:

  • ./test-run.sh

If the test run is successful, you should see some random text generated by the model. Each run will produce different output, but as long as it generates coherent text, everything is set up correctly.

Running the Chat Implementation

Finally, let's run the chat implementation using the installed local language model. Execute the following command in the Terminal:

  • ./run_chat_local.sh

This will launch a chat-like interface where you can Interact with the language model. You will see a user prompt and responses generated by the model. Feel free to ask questions or provide input and observe the model's responses.

Conclusion

Congratulations! You have successfully installed a local language model on your Apple Silicon Mac M1 or M2 Max machine. We have covered the necessary steps, including installing Homebrew, cloning the Lamma.cpp project, downloading the Lamma model, and running the chat implementation. Remember, you can also explore larger models with billions of parameters if your machine supports them. Enjoy experimenting with local language models and stay tuned for more tutorials in the future!


Highlights

FAQ

Q: Can I install a larger language model with more parameters?

A: Yes, you can search for model files with 30 billion or 65 billion parameters if your machine supports them. Keep in mind that larger models may be slower in generating responses.
