How to use
Prompt 格式如下:
<|im_start|> {English Text} <|endoftext|>
Directly using transformers
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_path = 'Mxode/NanoTranslator-XXL'
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path)
def translate(text: str, model, **kwargs):
generation_args = dict(
max_new_tokens = kwargs.pop("max_new_tokens", 512),
do_sample = kwargs.pop("do_sample", True),
temperature = kwargs.pop("temperature", 0.55),
top_p = kwargs.pop("top_p", 0.8),
top_k = kwargs.pop("top_k", 40),
**kwargs
)
prompt = "<|im_start|>" + text + "<|endoftext|>"
model_inputs = tokenizer([prompt], return_tensors="pt").to(model.device)
generated_ids = model.generate(model_inputs.input_ids, **generation_args)
generated_ids = [
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
return response
text = "Each step of the cell cycle is monitored by internal."
response = translate(text, model, max_new_tokens=64, do_sample=False)
print(response)
ONNX
根据实际测试,使用 ONNX 模型推理会比直接使用 transformers 推理要快 2~10 倍。
如果希望使用 ONNX 模型,那么你需要手动切换到 onnx 分支并从本地加载。
参考文档:
Using ORTModelForCausalLM
from optimum.onnxruntime import ORTModelForCausalLM
from transformers import AutoTokenizer
model_path = "your/folder/to/onnx_model"
ort_model = ORTModelForCausalLM.from_pretrained(model_path)
tokenizer = AutoTokenizer.from_pretrained(model_path)
text = "Each step of the cell cycle is monitored by internal."
response = translate(text, ort_model, max_new_tokens=64, do_sample=False)
print(response)
Using pipeline
from optimum.pipelines import pipeline
model_path = "your/folder/to/onnx_model"
pipe = pipeline("text-generation", model=model_path, accelerator="ort")
text = "Each step of the cell cycle is monitored by internal."
response = pipe(text, max_new_tokens=64, do_sample=False)
response
