--smoothquant	None	Set the α parameter for Smoothquant quantization (float value)
--per_channel	False	Use per-channel static scaling factor for GEMM's result
--per_token	False	Use per-token dynamic scaling factor for activations
--int8_kv_cache	False	Use INT8 quantization for KV cache
--ammo_quant_ckpt_path	None	Path to a quantized model checkpoint in .npz format

--load_model_on_cpu	False	Load the model on CPU
--use_parallel_embedding	False	Enable embedding parallelism
--embedding_sharding_dim	0	Dimension for sharding the embedding lookup table (0: vocab dimension, 1: hidden dimension)
--use_embedding_sharing	False	Try to reduce the engine size by sharing the embedding lookup table between two layers
--output_dir	'tllm_checkpoint'	Path to save the TensorRT-LLM checkpoint
--workers	1	Number of workers for converting checkpoint in parallel
--moe_num_experts	0	Number of experts to use for MOE layers
--moe_top_k	0	Top_k value to use for MOE layers (defaults to 1 if --moe_num_experts is set)
--moe_tp_mode	MoeConfig.ParallelismMode.TENSOR_PARALLEL	Controls how to distribute experts in TP (check layers/moe.py for accepted values)
--moe_renorm_mode	MoeConfig.ExpertScaleNormalizationMode.RENORM	Controls renormalization after gate logits (check layers/moe.py for accepted values)
--save_config_only	False	Only save the model config without reading and converting weights (for debugging)

These arguments allow you to customise the behavior of the **`convert_checkpoint.py`** script according to your specific requirements. You can provide the desired values for these arguments when running the script.
