Welcome to your one-stop guide for quantizing the CodeQwen1.5-7B-Chat model using ExLlama v2! In this article, we’ll break it down in an easy-to-understand approach, so let’s dive in!
What is ExLlama v2?
ExLlama v2 is a library designed for an efficient model quantization and allows practitioners to optimize their models while maintaining performance. Think of it like consolidating a large library of books into a more manageable and categorized shelves, without losing any vital information.
Getting Started with CodeQwen
To get the ball rolling, you need the CodeQwen model. It’s essential first to familiarize yourself with the available sizes and understand their implications.
Available Sizes
- 8_0: 8.0 bits – Maximum quality, near unquantized performance.
- 6_5: 6.5 bits – Recommended for a good trade-off of size vs performance.
- 5_0: 5.0 bits – Slightly lower quality but works on 8GB cards.
- 4_25: 4.25 bits – Slightly higher quality than GPTQ equivalent.
- 3_5: 3.5 bits – Lower quality; advisable to use only if necessary.
Download Instructions
You can download the specific branch of the model either via git or the Hugging Face Hub.
Using Git
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/CodeQwen1.5-7B-Chat-exl2
Using Hugging Face Hub
First, ensure that you have the Hugging Face Hub installed:
pip3 install huggingface-hub
Now, to download a specific branch:
- Linux:
huggingface-cli download bartowski/CodeQwen1.5-7B-Chat-exl2 --revision 6_5 --local-dir CodeQwen1.5-7B-Chat-exl2-6_5 --local-dir-use-symlinks False
- Windows:
huggingface-cli download bartowski/CodeQwen1.5-7B-Chat-exl2 --revision 6_5 --local-dir CodeQwen1.5-7B-Chat-exl2-6.5 --local-dir-use-symlinks False
Troubleshooting
If you encounter any issues during the quantization process, here are some troubleshooting tips:
- Ensure your git or Hugging Face Hub client is up-to-date.
- Verify that the branch names used for cloning or downloading are correct.
- Double-check your local directory permissions, especially on Windows.
