* Set C locale for consistent float formatting across all binaries. * Add C locale setting to all tools binaries Add std::setlocale(LC_NUMERIC, "C") to all 16 binaries in the tools/ directory to ensure consistent floating-point formatting. * Apply suggestion from @JohannesGaessler --------- Co-authored-by: Johannes Gäßler <johannesg@5d6.de> |

cvector-generator
This example demonstrates how to generate a control vector using gguf models.

Examples
# 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)
./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
