While the current version of [llama.cpp](https://github.com/ggerganov/llama.cpp) already supports such large context lengths, it requires quantized files in the new GGUF format - and that's where this repo comes in: it contains the following quantizations of the original weights from Together's fined-tuned model * [Q2_K](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q2_K.gguf) * [Q3_K_S](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q3_K_S.gguf), [Q3_K_M](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q3_K_M.gguf) (aka Q3_K) and [Q3_K_L](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q3_K_L.gguf) * [Q4_0](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q4_0.gguf), [Q4_1](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q4_1.gguf), [Q4_K_S](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q4_K_S.gguf) and [Q4_K_M](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q4_K_M.gguf) (aka Q4_K) * [Q5_0](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q5_0.gguf), [Q5_1](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q5_1.gguf), [Q5_K_S](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q5_K_S.gguf) and [Q5_K_M](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q5_K_M.gguf) (aka Q5_K) * [Q6_K](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q6_K.gguf), * [Q8_0](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-Q8_0.gguf) and * [F16](https://huggingface.co/rozek/LLaMA-2-7B-32K_GGUF/blob/main/LLaMA-2-7B-32K-f16.gguf) (unquantized) > Nota bene: while RoPE makes inferences with large contexts possible, you still need an awful lot of RAM > when doing so. And since "32K" does not mean that you always have to use a context size of 32768 (only that > the model was fine-tuned for that size), it is recommended that you keep your context as small as possible ## How Quantization was done ## Since the author does not want arbitrary Python stuff to loiter on his computer, the quantization was done using [Docker](https://www.docker.com/). Assuming that you have the [Docker Desktop](https://www.docker.com/products/docker-desktop/) installed on your system and also have a basic knowledge of how it is used, you may just follow the instructions shown below in order to generate your own quantizations: > Nota bene: you will need 30+x GB of free disk space, at least - depending on your quantization 1. create a new folder called `llama.cpp_in_Docker`
this folder will later be mounted into the Docker container and store the quantization results 2. download the weights for the fine-tuned LLaMA-2 model from [Hugging Face](https://huggingface.co/togethercomputer/LLaMA-2-7B-32K) into a subfolder of `llama.cpp_in_Docker` (let's call the new folder `LLaMA-2-7B-32K`) 3. within the Docker Desktop, search for and download a `basic-python` image - just use one of the most popular ones 4. from a terminal session on your host computer (i.e., not a Docker container!), start a new container for the downloaded image which mounts the folder we created before:
``` docker run --rm \ -v ./llama.cpp_in_Docker:/llama.cpp \ -t basic-python /bin/bash ``` (you may have to adjust the path to your local folder) 5. back in the Docker Desktop, open the "Terminal" tab of the started container and enter the following commands:
``` apt update apt-get install software-properties-common -y apt-get update apt-get install g++ git make -y cd /llama.cpp git clone https://github.com/ggerganov/llama.cpp cd llama.cpp ``` 6. now open the "Files" tab and navigate to the file `/llama.cpp/llama.cpp/Makefile`, right-click on it and choose "Edit file" 7. search for `aarch64`, and - in the line found (which looks like `ifneq ($(filter aarch64%,$(UNAME_M)),)`) - change `ifneq` to `ifeq` 8. save your change using the disk icon in the upper right corner of the editor pane and open the "Terminal" tab again 9. now enter the following commands:
``` make python3 -m pip install -r requirements.txt python3 convert.py ../LLaMA-2-7B-32K ``` 10. you are now ready to run the actual quantization, e.g., using
``` ./quantize ../LLaMA-2-7B-32K/ggml-model-f16.gguf \ ../LLaMA-2-7B-32K/LLaMA-2-7B-32K-Q4_0.gguf Q4_0 ``` 11. run any quantizations you need and stop the container when finished (the container will automatically be deleted deleted but the generated files will remain available on your host computer) 12. the `basic-python` image may also be deleted (manually) unless you plan to use it again in the near future You are now free to move the quanitization results to where you need them and run inferences with context lengths up to 32K (depending on the amount of memory you will have available - long contexts need an awful lot of RAM) ## License ## Concerning the license(s): * the [original model](https://ai.meta.com/llama/) (from Meta AI) was released under a rather [permissive license](https://ai.meta.com/llama/license/) * the fine tuned model from Together Computer uses the [same license](https://huggingface.co/togethercomputer/LLaMA-2-7B-32K/blob/main/README.md) * as a consequence, this repo does so as well
