## Model

Llama-2-7b-qlora-moss-003-sft is fine-tuned from [Llama-2-7b](https://huggingface.co/meta-llama/Llama-2-7b-hf) with [moss-003-sft](https://huggingface.co/datasets/fnlp/moss-003-sft-data) dataset by [XTuner](https://github.com/InternLM/xtuner).


## Quickstart

### Usage with HuggingFace libraries

```python
import torch
from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig, StoppingCriteria
from transformers.generation import GenerationConfig

class StopWordStoppingCriteria(StoppingCriteria):
    def __init__(self, tokenizer, stop_word):
        self.tokenizer = tokenizer
        self.stop_word = stop_word
        self.length = len(self.stop_word)
    def __call__(self, input_ids, *args, **kwargs) -> bool:
        cur_text = self.tokenizer.decode(input_ids[0])
        cur_text = cur_text.replace('\r', '').replace('\n', '')
        return cur_text[-self.length:] == self.stop_word

tokenizer = AutoTokenizer.from_pretrained('meta-llama/Llama-2-7b-hf', trust_remote_code=True)
quantization_config = BitsAndBytesConfig(load_in_4bit=True, load_in_8bit=False, llm_int8_threshold=6.0, llm_int8_has_fp16_weight=False, bnb_4bit_compute_dtype=torch.float16, bnb_4bit_use_double_quant=True, bnb_4bit_quant_type='nf4')
model = AutoModelForCausalLM.from_pretrained('meta-llama/Llama-2-7b-hf', quantization_config=quantization_config, device_map='auto', trust_remote_code=True).eval()
model = PeftModel.from_pretrained(model, 'xtuner/Llama-2-7b-qlora-moss-003-sft')
gen_config = GenerationConfig(max_new_tokens=1024, do_sample=True, temperature=0.1, top_p=0.75, top_k=40)

# Note: In this example, we disable the use of plugins because the API depends on additional implementations.
# If you want to experience plugins, please refer to XTuner CLI!
