## Exllama v2 Quantizations of SuperNova-Medius |
|
|
|
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.2.3">turboderp's ExLlamaV2 v0.2.3</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/arcee-ai/SuperNova-Medius |

## Download instructions |
|
|
|
With git: |
|
|
|
```shell |
|
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/SuperNova-Medius-exl2 SuperNova-Medius-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/SuperNova-Medius-exl2 --revision 6_5 --local-dir SuperNova-Medius-exl2-6_5 |
|
``` |
|
|
|
Windows (which apparently doesn't like _ in folders sometimes?): |
|
|
|
```shell |
|
huggingface-cli download bartowski/SuperNova-Medius-exl2 --revision 6_5 --local-dir SuperNova-Medius-exl2-6.5 |
|
``` |
