Model Card for RigoChat-7b-v2-GGUF
Introduction
This repo contains IIC/RigoChat-7b-v2 model in the GGUF Format, with the original weights and quantized to different precisions.
The llama.cpp library has been used to transform the parameters into GGUF format, as well as to perform the quantizations. Specifically, the following command has been used to obtain the model in full precision:
- To download the weights:
from huggingface_hub import snapshot_download
import os
model_id="IIC/RigoChat-7b-v2"
os.environ["MODEL_DIR"] = snapshot_download(
repo_id=model_id,
local_dir="model",
local_dir_use_symlinks=False,
revision="main",
)
- To transform to
FP16:
python ./llama.cpp/convert_hf_to_gguf.py $MODEL_DIR --outfile rigochat-7b-v2-F16.gguf --outtype f16
Nevertheless, you can download this weights here.
To quantize rigochat-7b-v2-F16.gguf into diferent sizes, first, we calculates an importance matrix as follows:
./llama.cpp/llama-imatrix -m ./rigochat-7b-v2-fp16.gguf -f train_data.txt -c 1024
where train_data.txt is an spanish raw-text dataset for calibration. This generates an imatrix.dat file that we can use to quantize the original model. For example, to get the Q4_K_M precision with this config, do:
./llama.cpp/llama-quantize --imatrix imatrix.dat ./rigochat-7b-v2-fp16.gguf ./quantize_models/rigochat-7b-v2-Q4_K_M.gguf Q4_K_M
and so on. Yo can do:
./llama.cpp/llama-quantize --help
to see all the quantization options. To check how imatrix works, this example can be usefull. For more information on the quantization types, see this link.
Disclaimer
The train_data.txt dataset is optional for most quantizations. We have used an experimental dataset to obtain all possible quantizations. However, we highly recommend downloading the weights in full precision: rigochat-7b-v2-fp16.gguf and trying to quantize the model with your own datasets, adapted to the use case you want to use.
How to Get Started with the Model
You can do, for example
./llama.cpp/llama-cli -m ./rigochat-7b-v2-Q8_0.gguf -co -cnv -p "your system." -fa -ngl -1 -n 512
or
./llama.cpp/llama-server -m ./rigochat-7b-v2-Q8_0.gguf -co -cnv -p "your system." -fa -ngl -1 -n 512
Evaluation
The evaluations are discussed in greater detail in the paper and the official repository. Here, we present only the graph illustrating how the model's performance improves as precision increases.
