A simple example which demonstrates how to use callback during the inference. It simply prints to the console all operations and tensor data.
Usage:
llama-eval-callback \
--hf-repo ggml-org/models \
--hf-file phi-2/ggml-model-q4_0.gguf \
--model phi-2-q4_0.gguf \
--prompt hello \
--seed 42 \
-ngl 33Will print:
llm_load_tensors: offloaded 33/33 layers to GPU
