## Description: |
|
|
|
_This repository contains EXL2 model files for [WizardLM's WizardLM 70B V1.0](https://huggingface.co/WizardLM/WizardLM-70B-V1.0)._ |
|
|
|
EXL2 is a new format used by ExLlamaV2 – https://github.com/turboderp/exllamav2. EXL2 is based on the same optimization method as GPTQ. The format allows for mixing quantization |
|
levels within a model to achieve any average bitrate between 2 and 8 bits per weight. |

## Quantization process: |
|
|
|
| Original Model | → | (optional) float16 or bfloat16 Model* | → | Safetensors Model** | → | EXL2 Model | |
|
| -------------- | --- | ------------- | --- | ---------------- | --- | ---------- | |
|
| [WizardLM 70B V1.0](https://huggingface.co/WizardLM/WizardLM-70B-V1.0) | → | [WizardLM 70B V1.0-HF](https://huggingface.co/simsim314/WizardLM-70B-V1.0-HF)* | → | Safetensors** | → | EXL2 | |
|
|
|
Example to convert WizardLM-70B-V1.0-HF to EXL2 4.0 bpw with 6-bit head: |
|
|
|
``` |
|
mkdir -p ~/EXL2/WizardLM-70B-V1.0-HF_4bit # Create the output directory |
|
python convert.py -i ~/float16_safetensored/WizardLM-70B-V1.0-HF -o ~/EXL2/WizardLM-70B-V1.0-HF_4bit -c ~/EXL2/0000.parquet -b 4.0 -hb 6 |
|
``` |
|
|
|
\* Use the following script to convert your local pytorch_model bin files to float16 (you can also choose bfloat16) + safetensors all in one go: |
|
|
|
- https://github.com/oobabooga/text-generation-webui/blob/main/convert-to-safetensors.py |
|
(best for sharding and float16/FP16 or bfloat16/BF16 conversion) |
|
|
|
Example to convert [WizardLM 70B V1.0](https://huggingface.co/WizardLM/WizardLM-70B-V1.0) directly to float16 safetensors in 10GB shards: |
|
|
|
``` |
|
python convert-to-safetensors.py ~/original/WizardLM-70B-V1.0 --output ~/float16_safetensored/WizardLM-70B-V1.0 --max-shard-size 10GB |
|
``` |
|
|
|
Use `--bf16` if you'd like to try bfloat16 instead, but note that there are concerns about quantization quality – https://github.com/turboderp/exllamav2/issues/30#issuecomment-1719009289 |
|
|
|
\*\* Use any one of the following scripts to convert your local pytorch_model bin files to safetensors: |
|
|
|
- https://github.com/turboderp/exllamav2/blob/master/util/convert_safetensors.py (official ExLlamaV2) |
|
- https://huggingface.co/Panchovix/airoboros-l2-70b-gpt4-1.4.1-safetensors/blob/main/bin2safetensors/convert.py (recommended) |
|
