Mistral-7B-v0.1-AWQ-G128-INT4-SYM-BF16

• Introduction

  This model was created by applying Quark with calibration samples from Pile dataset.

• Quantization Stragegy

  • Quantized Layers: All linear layers excluding "lm_head"
  • Weight: INT4 symmetric per-group, group_size=128
  • Pre-trained Model data type: BFloat16

• Quick Start

1. Download and install Quark
2. Run the quantization script in the example folder using the following command line:

   export MODEL_DIR = [local model checkpoint folder] or mistralai/Mistral-7B-v0.1 
   # single GPU
   python3 quantize_quark.py --model_dir $MODEL_DIR \
                             --data_type bfloat16 \
                             --quant_scheme w_int4_per_group_sym \
                             --num_calib_data 128 \
                             --quant_algo awq \
                             --dataset pileval_for_awq_benchmark \
                             --seq_len 512 \
                             --output_dir Mistral-7B-v0.1-AWQ-G128-INT4-SYM-BF16 \
                             --model_export quark_safetensors
   # cpu
   python3 quantize_quark.py --model_dir $MODEL_DIR \
                             --data_type bfloat16 \
                             --quant_scheme w_int4_per_group_sym \
                             --num_calib_data 128 \
                             --quant_algo awq \
                             --dataset pileval_for_awq_benchmark \
                             --seq_len 512 \
                             --output_dir Mistral-7B-v0.1-AWQ-G128-INT4-SYM-BF16 \
                             --model_export quark_safetensors \
                             --device cpu
   

Deployment

Quark has its own export format, quark_safetensors, which is compatible with autoAWQ exports.

Evaluation

Quark currently uses perplexity(PPL) as the evaluation metric for accuracy loss before and after quantization.The specific PPL algorithm can be referenced in the quantize_quark.py. The quantization evaluation results are conducted in pseudo-quantization mode, which may slightly differ from the actual quantized inference accuracy. These results are provided for reference only.
