模型介绍/Introduction
源2.0 是浪潮信息发布的新一代基础语言大模型。我们开源了全部的3个模型源2.0-102B，源2.0-51B和源2.0-2B。并且我们提供了预训练，微调，推理服务的相关脚本，以供研发人员做进一步的开发。源2.0是在源1.0的基础上，利用更多样的高质量预训练数据和指令微调数据集，令模型在语义、数学、推理、代码、知识等不同方面具备更强的理解能力。
Yuan2.0 is a new generation Fundamental Large Language Model developed by IEIT System. We have published all three models, Yuan 2.0-102B, Yuan 2.0-51B, and Yuan 2.0-2B. And we provide relevant scripts for pretraining, fine-tuning, and inference services for other developers. Yuan2.0 is based on Yuan1.0, utilizing a wider range of high-quality pre training data and instruction fine-tuning datasets to enhance the model's understanding of semantics, mathematics, reasoning, code, knowledge, and other aspects.
代码调用/Code Usage
可以通过如下代码调用 Yuan2-2B 模型来生成文本：
You can generate text by invoking the Yuan2-2B model with the following code:
1import torch, transformers
2import sys, os
3sys.path.append(
4 os.path.abspath(os.path.join(os.path.dirname(__file__), os.path.pardir)))
5from transformers import AutoModelForCausalLM,AutoTokenizer,LlamaTokenizer
6
7print("Creat tokenizer...")
8tokenizer = LlamaTokenizer.from_pretrained('IEITYuan/Yuan2-2B-Februa-hf', add_eos_token=False, add_bos_token=False, eos_token='<eod>')
9tokenizer.add_tokens(['<sep>', '<pad>', '<mask>', '<predict>', '<FIM_SUFFIX>', '<FIM_PREFIX>', '<FIM_MIDDLE>','<commit_before>','<commit_msg>','<commit_after>','<jupyter_start>','<jupyter_text>','<jupyter_code>','<jupyter_output>','<empty_output>'], special_tokens=True)
10
11print("Creat model...")
12model = AutoModelForCausalLM.from_pretrained('IEITYuan/Yuan2-2B-Februa-hf', device_map='auto', torch_dtype=torch.bfloat16, trust_remote_code=True)
13
14inputs = tokenizer("请问目前最先进的机器学习算法有哪些？", return_tensors="pt")["input_ids"].to("cuda:0")
15outputs = model.generate(inputs,do_sample=False,max_length=100)
16print(tokenizer.decode(outputs[0]))

Benchmark评估/Benchmark Evaluation
我们提供了
HumanEval，
AGIEval-GK-Math，
GSM8K和
TruthfulQA的评估脚本。在4个典型任务上，我们用源2.0不同版本模型上进行了性能测试。
We have provided evaluation scripts for
HumanEval,
AGIEval-GK-Math,
GSM8K and
TruthfulQA. Performance tests were conducted on different versions of the Yuan2.0 model for four typical tasks.
| Model | GSM8K | AGIEval-GK-Math-QA | AGIEval-GK-Math-Cloze | HumanEval | TurthfulQA |
|---|
| GPT-4 | 92% | 47.0% | 16.1% | 86.6% | 59% |
| ChatGPT | 68.6%* | 36.5% | 7.3% | 66.5%* | 34%* |
| Llama2 | 56.8% | - | - | 29.9% | - |
