Description

I attempted to run a low-level API in version 0.2.11, but both installing from pypi and compiling from source failed. python: 3.10.12 llama_cpp_python: 0.2.11

{llama-cpp-python/examples/low_level_api}$ python low_level_api_llama_cpp.py
Traceback (most recent call last):
  File ".../llama-cpp-python/examples/low_level_api/low_level_api_llama_cpp.py", line 15, in <module>
    model = llama_cpp.llama_load_model_from_file(MODEL_PATH.encode('utf-8'), lparams)
  File ".../llama-cpp-python/llama_cpp/llama_cpp.py", line 498, in llama_load_model_from_file
    return _lib.llama_load_model_from_file(path_model, params)
ctypes.ArgumentError: argument 2: TypeError: expected llama_model_params instance instead of llama_context_params

Contributor guide

Research direction
Inspect the function signature in `llama cpp.py` to ensure `llama load model from file` receives `llama model params` instead of `llama context params`. Check the ctypes binding and the call site in the example.
