If you’re a developer or data scientist looking to optimize your machine learning models, you’re in the right place! In this guide, we’ll explore how to quantize the Exllama v2 Magnum-12B model using the available resources, specifically focusing on the ExLlamaV2 v0.1.8 release for this task. Let’s get started!

Understanding the Quantization Process

Quantization is like preparing a fine meal. Imagine you have a complex recipe (our model) that uses a lot of ingredients (data). When you quantize, you’re simplifying that recipe by reducing the number of ingredients while still maintaining its essence. In our case, we aim to reduce the bits used per weight in the model, which helps in speeding up inference and reducing memory usage without significantly impacting performance.

Model and Branch Information

• The main branch contains the measurement.json file.
• Other branches contain individual bits per weight. Check them out for further conversions.

Download Instructions

Follow these instructions to download your desired model branch:

1. Using Git

git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/magnum-12b-v2.5-kto-exl2

2. Using Hugging Face Hub

This method is credited to TheBloke:

pip3 install huggingface-hub

To download the main branch to a folder:

mkdir magnum-12b-v2.5-kto-exl2

huggingface-cli download bartowski/magnum-12b-v2.5-kto-exl2 --local-dir magnum-12b-v2.5-kto-exl2

To download from another branch, add the revision parameter:

For Linux:

mkdir magnum-12b-v2.5-kto-exl2-6_5

huggingface-cli download bartowski/magnum-12b-v2.5-kto-exl2 --revision 6_5 --local-dir magnum-12b-v2.5-kto-exl2-6_5

For Windows:

mkdir magnum-12b-v2.5-kto-exl2-6.5

huggingface-cli download bartowski/magnum-12b-v2.5-kto-exl2 --revision 6_5 --local-dir magnum-12b-v2.5-kto-exl2-6.5

Troubleshooting

If you run into any issues during the quantization or downloading process, here are a few troubleshooting steps:

• Ensure you have the latest version of Python and Hugging Face CLI installed.
• Check your internet connection, as interruptions can cause download failures.
• If a command doesn’t work, try running your terminal or command prompt as an administrator.
