 You can load pre-quantized 4bit models with the argument `--load_quantized_model`.
 Currently, uint4 checkpoints and single device are supported.
 More information on enabling 4 bit inference in SynapseAI is available here:

 Below is an example to load a model with 4bit checkpoints from Hugging Face.
 Please note that model name is denoted as `<model_path_in_hugging_face>`.
