Signature adapted from https://github.com/ml-explore/mlx-examples/blob/4872727/llms/mlx_lm/utils.py#L422 Parameters ---------- Args: path_or_hf_repo (Path): The path or the huggingface repository to load the model from. tokenizer_config (dict, optional): Configuration parameters specifically for the tokenizer. Defaults to an empty dictionary. model_config(dict, optional): Configuration parameters specifically for the model. Defaults to an empty dictionary. adapter_path (str, optional): Path to the LoRA adapters. If provided, applies LoRA layers to the model. Default: ``None``. lazy (bool): If False eval the model parameters to make sure they are loaded in memory before returning, otherwise they will be loaded when needed.
