## Downloading using huggingface-cli
|
98 |
+
If you do not have hugginface-cli installed:
|
99 |
+
```
|
100 |
+
pip install -U "huggingface_hub[cli]"
|
101 |
+
```
|
102 |
+
Download the specific file you want:
|
103 |
+
```
|
104 |
+
huggingface-cli download legraphista/Qwen2-Math-1.5B-Instruct-IMat-GGUF --include "Qwen2-Math-1.5B-Instruct.Q8_0.gguf" --local-dir ./
|
105 |
+
```
|
106 |
+
If the model file is big, it has been split into multiple files. In order to download them all to a local folder, run:
|
107 |
+
```
|
108 |
+
huggingface-cli download legraphista/Qwen2-Math-1.5B-Instruct-IMat-GGUF --include "Qwen2-Math-1.5B-Instruct.Q8_0/*" --local-dir ./
|
109 |
+
# see FAQ for merging GGUF's
|

+
```

### Llama.cpp
|
143 |
+
```
|
144 |
+
llama.cpp/main -m Qwen2-Math-1.5B-Instruct.Q8_0.gguf --color -i -p "prompt here (according to the chat template)"

## FAQ
|
150 |
+
|
151 |
+
### Why is the IMatrix not applied everywhere?
|
152 |
+
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).
|
153 |
+
|
154 |
+
### How do I merge a split GGUF?
|
155 |
+
1. Make sure you have `gguf-split` available
|
156 |
+
- To get hold of `gguf-split`, navigate to https://github.com/ggerganov/llama.cpp/releases
|
157 |
+
- Download the appropriate zip for your system from the latest release
|
158 |
+
- Unzip the archive and you should be able to find `gguf-split`
|
159 |
+
2. Locate your GGUF chunks folder (ex: `Qwen2-Math-1.5B-Instruct.Q8_0`)
|
160 |
+
3. Run `gguf-split --merge Qwen2-Math-1.5B-Instruct.Q8_0/Qwen2-Math-1.5B-Instruct.Q8_0-00001-of-XXXXX.gguf Qwen2-Math-1.5B-Instruct.Q8_0.gguf`
|
161 |
+
- Make sure to point `gguf-split` to the first chunk of the split.
