## Examples
|
|
|
|
```sh
|
|
# CPU only
|
|
./cvector-generator -m ./llama-3.Q4_K_M.gguf
|
|
|
|
# With GPU
|
|
./cvector-generator -m ./llama-3.Q4_K_M.gguf -ngl 99
|
|
|
|
# With advanced options
|
|
./cvector-generator -m ./llama-3.Q4_K_M.gguf -ngl 99 --pca-iter 2000 --pca-batch 100
|
|
|
|
# Using mean value instead of PCA
|
|
./cvector-generator -m ./llama-3.Q4_K_M.gguf --method mean
|
|
|
|
# To see help message
|
|
./cvector-generator -h
|
|
# Then, have a look at "cvector" section
|
|
```

## Tips and tricks
|
|
|
|
If you have multiple lines per prompt, you can escape the newline character (change it to `\n`). For example:
|
|
|
|
```
|
|
<|im_start|>system\nAct like a person who is extremely happy.<|im_end|>
|
|
<|im_start|>system\nYou are in a very good mood today<|im_end|>
|
|
```
|
|
|
|
Example to use output file with `llama-cli`:
|
|
|
|
(Tips: The control vector works better when apply to layers higher than 10)
|
|
|
|
```sh
|
|
./llama-cli -m ./llama-3.Q4_K_M.gguf -p "<|start_header_id|>system<|end_header_id|>\n\nYou are a helpful assistant<|eot_id|><|start_header_id|>user<|end_header_id|>\n\nSing a song<|im_end|><|eot_id|><|start_header_id|>assistant<|end_header_id|>\n\n" --special --control-vector-scaled ./control_vector.gguf 0.8 --control-vector-layer-range 10 31

|
```
