Phi-3-mini-128k-instruct-int4

• Orginal model : microsoft/Phi-3-mini-128k-instruct
• Quantized using intel/auto-round

Description

Phi-3-mini-128k-instruct-int4 is an int4 model with group_size 128 of the microsoft/Phi-3-mini-128k-instruct.

The above model was quantized using AutoRound(Advanced Weight-Only Quantization Algorithm for LLMs) released by intel.

you can find out more in detail through the the GitHub Repository.

Training details

Cloning a repository(AutoRound)

git clone https://github.com/intel/auto-round

Enter into the examples/language-modeling folder

cd auto-round/examples/language-modeling
pip install -r requirements.txt

Install FlashAttention-2

pip install flash_attn==2.5.8

Here's an simplified code for quantization. In order to save memory in quantization, we set the batch size to 1.

python main.py \
  --model_name "microsoft/Phi-3-mini-128k-instruct" \
  --bits 4 \
  --group_size 128 \
  --train_bs 1 \
  --gradient_accumulate_steps 8 \
  --deployment_device 'gpu' \
  --output_dir "./save_ckpt" 

Model inference

Install the necessary packages

pip install auto_gptq
pip install optimum
pip install -U accelerate bitsandbytes datasets peft transformers
