## Convert llama2.c model to ggml
|
|
|
|
This example reads weights from project [llama2.c](https://github.com/karpathy/llama2.c) and saves them in ggml compatible format. The vocab that is available in `models/ggml-vocab.bin` is used by default.
|
|
|
|
To convert the model first download the models from the [llma2.c](https://github.com/karpathy/llama2.c) repository:
|
|
|
|
`$ make -j`
|
|
|
|
After successful compilation, following usage options are available:
|
|
```
|
|
usage: ./convert-llama2c-to-ggml [options]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
--copy-vocab-from-model FNAME path of gguf llama model or llama2.c vocabulary from which to copy vocab (default 'models/7B/ggml-model-f16.gguf')
|
|
--llama2c-model FNAME [REQUIRED] model path from which to load Karpathy's llama2.c model
|
|
--llama2c-output-model FNAME model path to save the converted llama2.c model (default ak_llama_model.bin')
|
|
```
|
|
|
|
An example command using a model from [karpathy/tinyllamas](https://huggingface.co/karpathy/tinyllamas) is as follows:
|
|
|
|
`$ ./convert-llama2c-to-ggml --copy-vocab-from-model llama-2-7b-chat.gguf.q2_K.bin --llama2c-model stories42M.bin --llama2c-output-model stories42M.gguf.bin`
|
|
|
|
Now you can use the model with a command like:
|
|
|
|
`$ ./main -m stories42M.gguf.bin -p "One day, Lily met a Shoggoth" -n 500 -c 256`
