## Downloading using huggingface-cli
If you do not have hugginface-cli installed:
```
pip install -U "huggingface_hub[cli]"
```
Download the specific file you want:
```
huggingface-cli download legraphista/shieldgemma-27b-IMat-GGUF --include "shieldgemma-27b.Q8_0.gguf" --local-dir ./
```
If the model file is big, it has been split into multiple files. In order to download them all to a local folder, run:
```
huggingface-cli download legraphista/shieldgemma-27b-IMat-GGUF --include "shieldgemma-27b.Q8_0/*" --local-dir ./
# see FAQ for merging GGUF's
```

## Inference
### Simple chat template
```
<bos>You are a policy expert trying to help determine whether a user prompt is in violation of the defined safety policies.
<start_of_turn>
Human Question: {next_user_prompt}
<end_of_turn>
Our safety principle is defined in the below:
* {guideline}
===
Does the human question violate the above principle? Your answer must start with 'Yes' or 'No'. And then walk through step by step to be sure we answer correctly.
```
### Llama.cpp
```
llama.cpp/main -m shieldgemma-27b.Q8_0.gguf --color -i -p "prompt here (according to the chat template)"
```

## FAQ
### Why is the IMatrix not applied everywhere?
According to [this investigation](https://www.reddit.com/r/LocalLLaMA/comments/1993iro/ggufs_quants_can_punch_above_their_weights_now/), it appears that lower quantizations are the only ones that benefit from the imatrix input (as per hellaswag results).
### How do I merge a split GGUF?
1. Make sure you have `gguf-split` available
- To get hold of `gguf-split`, navigate to https://github.com/ggerganov/llama.cpp/releases
- Download the appropriate zip for your system from the latest release
- Unzip the archive and you should be able to find `gguf-split`
2. Locate your GGUF chunks folder (ex: `shieldgemma-27b.Q8_0`)
3. Run `gguf-split --merge shieldgemma-27b.Q8_0/shieldgemma-27b.Q8_0-00001-of-XXXXX.gguf shieldgemma-27b.Q8_0.gguf`
- Make sure to point `gguf-split` to the first chunk of the split.
