About the acclerate problem with xpu

[K-Alex13]

After putting the model and inputs to xpu, the model is work now on intel laptop. But the inference time is about 588 seconds that is too long for me. I think maybe the gpu is not working right now, may I ask what is the problem here? Thank you very much for any response.

following is the code: `import torch import intel_extension_for_pytorch as ipex

from bigdl.llm.transformers import AutoModelForCausalLM, AutoModel from transformers import AutoTokenizer

import time import numpy as np

from gpu_benchmark_util import BenchmarkWrapper

model_path = r"D:\rag\test_api\Baichuan2-7B-Chat"

model_path = r"C:\Users\Administrator\yishuo\chatglm2-6b"

model = AutoModel.from_pretrained(model_path, trust_remote_code=True, optimize_model=True, load_in_4bit=True).eval()

input_ids = tokenizer.encode(prompt, return_tensors="pt") print("finish to load")

model = model.to('xpu')

model.model.embed_tokens.to('cpu')

model.transformer.embedding.to('cpu') input_ids = input_ids.to('xpu')

print("finish to xpu")

model = BenchmarkWrapper(model)

with torch.inference_mode():

wamup two times as use ipex

for i in range(7):

    print(f'Inference time: {end-st} s')
    output_str = tokenizer.decode(output[0], skip_special_tokens=True)

It seems that the model is not working on xpu right now, can you please help me to deal this problem? Thank you very much for any response.

see this section https://bigdl.readthedocs.io/en/latest/doc/LLM/Overview/install_gpu.html#best-known-configurations and follow it

model = AutoModelForCausalLM.from_pretrained(model_path, trust_remote_code=True, optimize_model=True, load_in_4bit=True).bfloat16().eval()

remove .bfloat16() for better performance and add cpu_embedding=True instead of model.transformer.embedding.to('cpu')

also see https://github.com/intel-analytics/BigDL/blob/main/python/llm/example/GPU/HF-Transformers-AutoModels/Model/baichuan2/generate.py, while this example is for linux, cpu_embedding=True is also required on Windows
