How to use this GPTQ model from Python code

First make sure you have AutoGPTQ installed:

pip install auto-gptq

Then try the following example code:

from transformers import AutoTokenizer, pipeline, logging
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig
import argparse

model_name_or_path = "TheBloke/WizardCoder-15B-1.0-GPTQ"
# Or to load it locally, pass the local download path
# model_name_or_path = "/path/to/models/TheBloke_WizardCoder-15B-1.0-GPTQ"

use_triton = False

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True)

model = AutoGPTQForCausalLM.from_quantized(model_name_or_path,
        use_safetensors=True,
        device="cuda:0",
        use_triton=use_triton,
        quantize_config=None)

# Prevent printing spurious transformers error when using pipeline with AutoGPTQ
logging.set_verbosity(logging.CRITICAL)

pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)

prompt_template = '''Below is an instruction that describes a task. Write a response that appropriately completes the request

### Instruction: {prompt}

### Response:'''
prompt = prompt_template.format(prompt="How do I sort a list in Python?")

outputs = pipe(prompt, max_new_tokens=256, do_sample=True, temperature=0.2, top_k=50, top_p=0.95)

print(outputs[0]['generated_text'])

Provided files

gptq_model-4bit--1g.safetensors

This will work with AutoGPTQ and CUDA versions of GPTQ-for-LLaMa. There are reports of issues with Triton mode of recent GPTQ-for-LLaMa. If you have issues, please use AutoGPTQ instead.

It was created without group_size to lower VRAM requirements, and with --act-order (desc_act) to boost inference accuracy as much as possible.

• gptq_model-4bit--1g.safetensors
  • Works with AutoGPTQ in CUDA or Triton modes.
  • Works with text-generation-webui, including one-click-installers.
  • Does not work with GPTQ-for-LLaMa.
  • Parameters: Groupsize = -1. Act Order / desc_act = True.

WizardCoder: Empowering Code Large Language Models with Evol-Instruct

To develop our WizardCoder model, we begin by adapting the Evol-Instruct method specifically for coding tasks. This involves tailoring the prompt to the domain of code-related instructions. Subsequently, we fine-tune the Code LLM, StarCoder, utilizing the newly created instruction-following training set.

News

• ? Our WizardCoder-15B-v1.0 model achieves the 57.3 pass@1 on the HumanEval Benchmarks , which is 22.3 points higher than the SOTA open-source Code LLMs.
• ? We released WizardCoder-15B-v1.0 trained with 78k evolved code instructions. Please checkout the Model Weights , and Paper .
• ? Please refer to our Twitter account https://twitter.com/WizardLM_AI and HuggingFace Repo https://huggingface.co/WizardLM . We will use them to announce any new release at the 1st time.

Comparing WizardCoder with the Closed-Source Models.

? The following figure shows that our WizardCoder attains the third position in this benchmark , surpassing Claude-Plus (59.8 vs. 53.0) and Bard (59.8 vs. 44.5). Notably, our model exhibits a substantially smaller size compared to these models.

❗ Note: In this study, we copy the scores for HumanEval and HumanEval+ from the LLM-Humaneval-Benchmarks . Notably, all the mentioned models generate code solutions for each problem utilizing a single attempt , and the resulting pass rate percentage is reported. Our WizardCoder generates answers using greedy decoding and tests with the same code .

Comparing WizardCoder with the Open-Source Models.

The following table clearly demonstrates that our WizardCoder exhibits a substantial performance advantage over all the open-source models. ❗ If you are confused with the different scores of our model (57.3 and 59.8), please check the Notes.

Model	HumanEval Pass@1	MBPP Pass@1
CodeGen-16B-Multi	18.3	20.9
CodeGeeX	22.9	24.4
LLaMA-33B	21.7	30.2
LLaMA-65B	23.7	37.7
PaLM-540B	26.2	36.8
PaLM-Coder-540B	36.0	47.0
PaLM 2-S	37.6	50.0
CodeGen-16B-Mono	29.3	35.3
Code-Cushman-001	33.5	45.9
StarCoder-15B	33.6	43.6*
InstructCodeT5+	35.0	--
WizardLM-30B 1.0	37.8	--
WizardCoder-15B 1.0	57.3	51.8

❗ Note: The reproduced result of StarCoder on MBPP.

❗ Note: The above table conducts a comprehensive comparison of our WizardCoder with other models on the HumanEval and MBPP benchmarks. We adhere to the approach outlined in previous studies by generating 20 samples for each problem to estimate the pass@1 score and evaluate with the same code . The scores of GPT4 and GPT3.5 reported by OpenAI are 67.0 and 48.1 (maybe these are the early version GPT4&3.5).

Call for Feedbacks

We welcome everyone to use your professional and difficult instructions to evaluate WizardCoder, and show us examples of poor performance and your suggestions in the issue discussion area. We are focusing on improving the Evol-Instruct now and hope to relieve existing weaknesses and issues in the the next version of WizardCoder. After that, we will open the code and pipeline of up-to-date Evol-Instruct algorithm and work with you together to improve it.

Online Demo

We will provide our latest models for you to try for as long as possible. If you find a link is not working, please try another one. At the same time, please try as many real-world and challenging code-related problems that you encounter in your work and life as possible. We will continue to evolve our models with your feedbacks.

Fine-tuning

We fine-tune WizardCoder using the modified code train.py from Llama-X . We fine-tune StarCoder-15B with the following hyperparameters:

Hyperparameter	StarCoder-15B
Batch size	512
Learning rate	2e-5
Epochs	3
Max length	2048
Warmup step	30
LR scheduler	cosine

To reproduce our fine-tuning of WizardCoder, please follow the following steps:

According to the instructions of Llama-X , install the environment, download the training code, and deploy. (Note: deepspeed==0.9.2 and transformers==4.29.2 )

Replace the train.py with the train_wizardcoder.py in our repo ( src/train_wizardcoder.py )

Login Huggingface:

huggingface-cli login

Execute the following training command:

deepspeed train_wizardcoder.py \
    --model_name_or_path "bigcode/starcoder" \
    --data_path "/your/path/to/code_instruction_data.json" \
    --output_dir "/your/path/to/ckpt" \

    --fp16 True

Inference

We provide the decoding script for WizardCoder, which reads a input file and generates corresponding responses for each sample, and finally consolidates them into an output file.

You can specify base_model , input_data_path and output_data_path in src\inference_wizardcoder.py to set the decoding model, path of input file and path of output file.

pip install jsonlines

The decoding command is:

python src\inference_wizardcoder.py \
    --base_model "/your/path/to/ckpt" \
    --input_data_path "/your/path/to/input/data.jsonl" \
    --output_data_path "/your/path/to/output/result.jsonl"

The format of data.jsonl should be:

{"idx": 11, "Instruction": "Write a Python code to count 1 to 10."}
{"idx": 12, "Instruction": "Write a Jave code to sum 1 to 10."}

The prompt for our WizardCoder in src\inference_wizardcoder.py is:

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
{instruction}

### Response:

Evaluation

We provide the evaluation script on HumanEval for WizardCoder.

According to the instructions of HumanEval , install the environment.

Run the following script to generate the answer.

model="/path/to/your/model"
temp=0.2
max_len=2048
pred_num=200
num_seqs_per_iter=2

output_path=preds/T${temp}_N${pred_num}

mkdir -p ${output_path}
echo 'Output path: '$output_path
echo 'Model to eval: '$model

# 164 problems, 21 per GPU if GPU=8
index=0
gpu_num=8
for ((i = 0; i < $gpu_num; i++)); do
  start_index=$((i * 21))
  end_index=$(((i + 1) * 21))

  gpu=$((i))
  echo 'Running process #' ${i} 'from' $start_index 'to' $end_index 'on GPU' ${gpu}
  ((index++))
  (
    CUDA_VISIBLE_DEVICES=$gpu python humaneval_gen.py --model ${model} \
      --start_index ${start_index} --end_index ${end_index} --temperature ${temp} \
      --num_seqs_per_iter ${num_seqs_per_iter} --N ${pred_num} --max_len ${max_len} --output_path ${output_path}
  ) &
  if (($index % $gpu_num == 0)); then wait; fi
done

Run the post processing code src/process_humaneval.py to collect the code completions from all answer files.

output_path=preds/T${temp}_N${pred_num}

echo 'Output path: '$output_path
python process_humaneval.py --path ${output_path} --out_path ${output_path}.jsonl --add_prompt
