**GGUF-IQ-Imatrix-Quantization-Script:** |
|
|
|
 |
|
|
|
Simple python script (`gguf-imat.py`) to generate various GGUF-IQ-Imatrix quantizations from a Hugging Face `author/model` input, for Windows and NVIDIA hardware. |
|
|
|
This is setup for a Windows machine with 8GB of VRAM, assuming use with an NVIDIA GPU. If you want to change the `-ngl` (number of GPU layers) amount, you can do so at [**line 120**](https://huggingface.co/FantasiaFoundry/GGUF-Quantization-Script/blob/main/gguf-imat.py#L120). This is only relevant during the `--imatrix` data generation. If you don't have enough VRAM you can decrease the `-ngl` amount or set it to 0 to only use your System RAM instead for all layers, this will make the imatrix data generation take longer, so it's a good idea to find the number that gives your own machine the best results. |

|
Your `imatrix.txt` is expected to be located inside the `imatrix` folder. I have already included a file that is considered a good starting option, [this discussion](https://github.com/ggerganov/llama.cpp/discussions/5263#discussioncomment-8395384) is where it came from. If you have suggestions or other imatrix data to recommend, please do so. |
|
|
|
Adjust `quantization_options` in [**line 133**](https://huggingface.co/FantasiaFoundry/GGUF-Quantization-Script/blob/main/gguf-imat.py#L133). |
|
|
|
**Hardware:** |
|
|
|
- NVIDIA GPU with 8GB of VRAM. |
|
- 32GB of system RAM. |
|
|
|
**Software Requirements:** |
|
- Git |
|
- Python 3.11 |
|
- `pip install huggingface_hub` |
|
|
|
**Usage:** |
|
``` |
|
python .\gguf-imat.py |
|
``` |
|
Quantizations will be output into the created `models\{model-name}-GGUF` folder. |
