| For NVIDIA cards install the CUDA toolkit | |
| Nvidia Maxwell or higher | |
| https://developer.nvidia.com/cuda-12-1-0-download-archive | |
| Nvidia Kepler or higher | |
| https://developer.nvidia.com/cuda-11-8-0-download-archive | |
| Restart your computer after installing the CUDA toolkit to make sure the PATH is set correctly. | |
| Visual Studio with desktop development for C++ is required. | |

| install the desktop development for C++ workload | |
| Make sure to have git and wget installed on your system. | |
| For Linux, install the build tools from your package manager. | |
| For example, on Ubuntu use: sudo apt-get install build-essential | |
| This may work with AMD cards but only on linux and possibly WSL2. I can't guarantee that it will work on AMD cards, I personally don't have one to test with. You may need to install stuff before starting. https://rocm.docs.amd.com/projects/install-on-linux/en/latest/tutorial/quick-start.html | |
| Only python 3.8 - 3.12 is known to work. If you have a higher/lower version of python, I can't guarantee that it will work. | |
| First setup your environment by using either windows.bat or linux.sh. If you want to upgrade your exllama version, you can run the setup script again. | |
| After setup is complete then you'll have a file called start-quant. Use this to run the quant script. | |
| Make sure that your storage space is 3x the amount of the model's size. To mesure this, take the number of billion parameters and mutliply by two, afterwards mutliply by 3 and that's the recommended storage. There's a chance you may get away with 2.5x the size as well. | |
| Make sure to also have a lot of RAM depending on the model. Have noticed gemma to use a lot. | |
| If you close the terminal or the terminal crashes, check the last BPW it was on and enter the remaining quants you wanted. It should be able to pick up where it left off. Don't type the BPW of completed quants as it will start from the beginning. You may also use ctrl + c to pause at any time during the quant process. | |
| To add more options to the quantization process, you can add them to line 199. All options: https://github.com/turboderp/exllamav2/blob/master/doc/convert.md | |
| Things may break in the future as it downloads the latest version of all the dependencies which may either change names or how they work. If something breaks, please open a discussion at https://huggingface.co/Anthonyg5005/hf-scripts/discussions | |
