Usage

from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
from peft import PeftModel

# Load 4-bit base model
bnb = BitsAndBytesConfig(load_in_4bit=True)
model = AutoModelForCausalLM.from_pretrained(
    "ljsysfurry/DeepSeek-R1-Distill-Qwen-7B",
    quantization_config=bnb,
    device_map="auto"
)
model = PeftModel.from_pretrained(model, "ljsysfurry/deepseek-r1-7b-novel-lora")

tok = AutoTokenizer.from_pretrained("ljsysfurry/DeepSeek-R1-Distill-Qwen-7B")
tok.pad_token = tok.eos_token

# Novel continuation example
text = "<|im_start|>system\n你是一位小说作者。请续写。<|im_end|>\n<|im_start|>user\n续写<|im_end|>\n<|im_start|>assistant\n他推开门，眼前是一条昏暗的走廊，"
inputs = tok(text, return_tensors="pt").to("cuda")
out = model.generate(**inputs, max_new_tokens=300, temperature=0.7, do_sample=True)
print(tok.decode(out[0], skip_special_tokens=True))

# Chat example

out = model.generate(**inputs, max_new_tokens=200, temperature=0.8, do_sample=True)
print(tok.decode(out[0], skip_special_tokens=True))
