## Credits
|
|
||||||
|
|
||||||
Thank you kalomaze and Dampf for assistance in creating the imatrix calibration dataset
|
|
||||||
|
|
||||||
Thank you ZeroWw for the inspiration to experiment with embed/output
|
|
||||||
|
|
||||||
## Downloading using huggingface-cli
|
|
||||||
|
|
||||||
First, make sure you have hugginface-cli installed:
|
|
||||||
|
|
||||||
```
|
```
|
||||||
pip install -U "huggingface_hub[cli]"
|
#Git模型下载
|
||||||
|
git clone https://www.modelscope.cn/LLM-Research/gemma-2-9b-it-GGUF.git
|
||||||
```
|
```
|
||||||
|
|
||||||
Then, you can target the specific file you want:
|
<p style="color: lightgrey;">如果您是本模型的贡献者，我们邀请您根据<a href="https://modelscope.cn/docs/ModelScope%E6%A8%A1%E5%9E%8B%E6%8E%A5%E5%85%A5%E6%B5%81%E7%A8%8B%E6%A6%82%E8%A7%88" style="color: lightgrey; text-decoration: underline;">模型贡献文档</a>，及时完善模型卡片内容。</p>
|
||||||
|
|
||||||
```
|
|
||||||
huggingface-cli download bartowski/gemma-2-9b-it-GGUF --include "gemma-2-9b-it-Q4_K_M.gguf" --local-dir ./
|
|
||||||
```
|
|
||||||
|
|
||||||
If the model is bigger than 50GB, it will have been split into multiple files. In order to download them all to a local folder, run:
|
|
||||||
|
|
||||||
```
|
|
||||||
huggingface-cli download bartowski/gemma-2-9b-it-GGUF --include "gemma-2-9b-it-Q8_0.gguf/*" --local-dir gemma-2-9b-it-Q8_0
|
|
||||||
```
|
|
||||||
|
|
||||||
You can either specify a new local-dir (gemma-2-9b-it-Q8_0) or download them all in place (./)
|
|
||||||
|
|
||||||
## Which file should I choose?
|
|
||||||
|
|
||||||
A great write up with charts showing various performances is provided by Artefact2 [here](https://gist.github.com/Artefact2/b5f810600771265fc1e39442288e8ec9)
|
|
||||||
|
|
||||||
The first thing to figure out is how big a model you can run. To do this, you'll need to figure out how much RAM and/or VRAM you have.
|
|
||||||
|
|
||||||
If you want your model running as FAST as possible, you'll want to fit the whole thing on your GPU's VRAM. Aim for a quant with a file size 1-2GB smaller than your GPU's total VRAM.
|
|
||||||
|
|
||||||
If you want the absolute maximum quality, add both your system RAM and your GPU's VRAM together, then similarly grab a quant with a file size 1-2GB Smaller than that total.
|
|
||||||
|
|
||||||
Next, you'll need to decide if you want to use an 'I-quant' or a 'K-quant'.
|
|
||||||
|
|
||||||
If you don't want to think too much, grab one of the K-quants. These are in format 'QX_K_X', like Q5_K_M.
|
|
||||||
|
|
||||||
If you want to get more into the weeds, you can check out this extremely useful feature chart:
|
|
||||||
|
|
||||||
[llama.cpp feature matrix](https://github.com/ggerganov/llama.cpp/wiki/Feature-matrix)
|
|
||||||
|
|
||||||
But basically, if you're aiming for below Q4, and you're running cuBLAS (Nvidia) or rocBLAS (AMD), you should look towards the I-quants. These are in format IQX_X, like IQ3_M. These are newer and offer better performance for their size.
|
|
||||||
|
|
||||||
These I-quants can also be used on CPU and Apple Metal, but will be slower than their K-quant equivalent, so speed vs performance is a tradeoff you'll have to decide.
|
|
||||||
|
|
||||||
The I-quants are *not* compatible with Vulcan, which is also AMD, so if you have an AMD card double check if you're using the rocBLAS build or the Vulcan build. At the time of writing this, LM Studio has a preview with ROCm support, and other inference engines have specific builds for ROCm.
