CodeQwen1.5-7B-MG-Verilog

Introduction

This model is a 4-bit quantized, fine-tuned version of CodeQwen1.5-7B on the MG-Verilog dataset. This model has been fine-tuned with the aim of improving the accuracy and latency of Verilog based Code Generation tasks. Developed in collabortion with @nimeshpandey

Training Procedures

This model has been trained using the A100 GPU in a Google Colab environment. The training script and Colab notebook can be found on this GitHub repository (https://github.com/pranaydang/qwen-train-verilog) (repository still in progress).

Here are the specifications of the process used:

• The MG-Verilog dataset was downloaded from Gatech-EIC/MG-Verilog. I have copied this dataset to my GitHub repository used to train the model.

• The dataset and the training script was uploaded to my Google Drive for easy access on Colab.

• A 4-bit quantized version of the base model is loaded using a quantization configuration using BitsAndBytesConfig and AutoModelForCausalLM.from_pretrained. The follwing are the specifications of the quantization configuration:

  load_in_4bit=True,
  bnb_4bit_use_double_quant=True,
  bnb_4bit_quant_type="nf4",
  bnb_4bit_compute_dtype=torch.bfloat16
  

• The model is prepared for k-bit training using prepare_model_for_kbit_training.

• The PEFT configuartion is set and a PeftModel is created from the quantized model. Here are the specifications of the PEFT configuration:

  r=64,
  lora_alpha=16,
  target_modules=["q_proj", "v_proj"],
  lora_dropout=0.05,
  bias="none",
  task_type=TaskType.CAUSAL_LM
  

• The Data Collator class implemented in the training script has been taken directly from qlora.py from the MG-Verilog GitHub (https://github.com/GATECH-EIC/mg-verilog)
