## Exllama v2 Quantizations of Qwen2-7B-Instruct |
|
|
|
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.1.4">turboderp's ExLlamaV2 v0.1.4</a> for quantization. |
|
|
|
<b>The "main" branch only contains the measurement.json, download one of the other branches for the model (see below)</b> |
|
|
|
Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions. |
|
|
|
Original model: https://huggingface.co/Qwen/Qwen2-7B-Instruct |
|
|
|
## Prompt format |
|
|
|
``` |
|
<|im_start|>system |
|
{system_prompt}<|im_end|> |
|
<|im_start|>user |
|
{prompt}<|im_end|> |
|
<|im_start|>assistant |
|
|
|
``` |
|
|
|
## Available sizes |
|
|
|
|
|
| Branch | Bits | lm_head bits | VRAM (4k) | VRAM (16k) | VRAM (32k) | Description | |
|
| ----- | ---- | ------- | ------ | ------ | ------ | ------------ | |
|
| [8_0](https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2/tree/8_0) | 8.0 | 8.0 | 8.4 GB | 9.8 GB | 11.8 GB | Maximum quality that ExLlamaV2 can produce, near unquantized performance. | |
|
| [6_5](https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2/tree/6_5) | 6.5 | 8.0 | 7.2 GB | 8.6 GB | 10.6 GB | Very similar to 8.0, good tradeoff of size vs performance, **recommended**. | |
|
| [5_0](https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2/tree/5_0) | 5.0 | 6.0 | 6.0 GB | 7.4 GB | 9.4 GB | Slightly lower quality vs 6.5, but usable on 8GB cards. | |
|
| [4_25](https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2/tree/4_25) | 4.25 | 6.0 | 5.3 GB | 6.7 GB | 8.7 GB | GPTQ equivalent bits per weight, slightly higher quality. | |
|
| [3_5](https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2/tree/3_5) | 3.5 | 6.0 | 4.7 GB | 6.1 GB | 8.1 GB | Lower quality, only use if you have to. | |

## Download instructions |
|
|
|
With git: |
|
|
|
```shell |
|
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/Qwen2-7B-Instruct-exl2 Qwen2-7B-Instruct-exl2-6_5 |
|
``` |
|
|
|
With huggingface hub (credit to TheBloke for instructions): |
|
|
|
```shell |
|
pip3 install huggingface-hub |
|
``` |
|
|
|
To download a specific branch, use the `--revision` parameter. For example, to download the 6.5 bpw branch: |
|
|
|
Linux: |
|
|
|
```shell |
|
huggingface-cli download bartowski/Qwen2-7B-Instruct-exl2 --revision 6_5 --local-dir Qwen2-7B-Instruct-exl2-6_5 |
|
``` |
|
|
|
Windows (which apparently doesn't like _ in folders sometimes?): |
|
|
|
```shell |
|
huggingface-cli download bartowski/Qwen2-7B-Instruct-exl2 --revision 6_5 --local-dir Qwen2-7B-Instruct-exl2-6.5 |
|
``` |
