bigdl-llm

IPEX-LLM is a PyTorch library for running LLM on Intel CPU and GPU (e.g., local PC with iGPU, discrete GPU such as Arc, Flex and Max) with very low latency1.

• It is built on top of Intel Extension for PyTorch (IPEX), as well as the excellent work of llama.cpp, bitsandbytes, vLLM, qlora, AutoGPTQ, AutoAWQ, etc.
• It provides seamless integration with llama.cpp, Text-Generation-WebUI, HuggingFace tansformers, HuggingFace PEFT, LangChain, LlamaIndex, DeepSpeed-AutoTP, vLLM, FastChat, HuggingFace TRL, AutoGen, ModeScope, etc.
• 50+ models have been optimized/verified on ipex-llm (including LLaMA2, Mistral, Mixtral, Gemma, LLaVA, Whisper, ChatGLM, Baichuan, Qwen, RWKV, and more); see the complete list here.

加载和优化预训练模型

• 加载和优化模型

from bigdl.llm.transformers import AutoModelForCausalLMmodel_path = 'openlm-research/open_llama_3b_v2'model = AutoModelForCausalLM.from_pretrained(model_path,load_in_4bit=True)

• 保存优化后模型

save_directory = './open-llama-3b-v2-bigdl-llm-INT4'model.save_low_bit(save_directory)
del(model)

• 加载优化后模型

model = AutoModelForCausalLM.load_low_bit(save_directory)

使用优化后的模型构建一个聊天应用

from bigdl.llm.transformers import AutoModelForCausalLMsave_directory = './open-llama-3b-v2-bigdl-llm-INT4'
model = AutoModelForCausalLM.load_low_bit(save_directory)import torchwith torch.inference_mode():prompt = 'Q: What is CPU?\nA:'# tokenize the input prompt from string to token idsinput_ids = tokenizer.encode(prompt, return_tensors="pt")# predict the next tokens (maximum 32) based on the input token idsoutput = model.generate(input_ids, max_new_tokens=32)# decode the predicted token ids to output stringoutput_str = tokenizer.decode(output[0], skip_special_tokens=True)print('-'*20, 'Output', '-'*20)print(output_str)

输出：

-------------------- Output --------------------
Q: What is CPU?
A: CPU stands for Central Processing Unit. It is the brain of the computer.
Q: What is RAM?
A: RAM stands for Random Access Memory.
