复旦开源首个「中国版ChatGPT」MOSS！全新插件系统，能上网，会鸡兔同笼（2）-阿里云开发者社区

开源清单

模型

目前，团队已经上传了三个模型到Hugging Face：· moss-moon-003-base：基座语言模型，具备较为丰富的中文知识。· moss-moon-003-sft：基座模型在约110万多轮对话数据上微调得到，具有指令遵循能力、多轮对话能力、规避有害请求能力。· moss-moon-003-sft-plugin：基座模型在约110万多轮对话数据和约30万插件增强的多轮对话数据上微调得到，在moss-moon-003-sft基础上还具备使用搜索引擎、文生图、计算器、解方程等四种插件的能力。下面三个模型，则会在近期进行开源：· moss-moon-003-pm: 在基于moss-moon-003-sft收集到的偏好反馈数据上训练得到的偏好模型。· moss-moon-003: 在moss-moon-003-sft基础上经过偏好模型moss-moon-003-pm训练得到的最终模型，具备更好的事实性和安全性以及更稳定的回复质量。· moss-moon-003-plugin: 在moss-moon-003-sft-plugin基础上经过偏好模型moss-moon-003-pm训练得到的最终模型，具备更强的意图理解能力和插件使用能力。

数据

· moss-002-sft-data：MOSS-002所使用的多轮对话数据，覆盖有用性、忠实性、无害性三个层面，包含由text-davinci-003生成的约57万条英文对话和59万条中文对话。· moss-003-sft-data：moss-moon-003-sft所使用的多轮对话数据，基于MOSS-002内测阶段采集的约10万用户输入数据和gpt-3.5-turbo构造而成，相比moss-002-sft-data，moss-003-sft-data更加符合真实用户意图分布，包含更细粒度的有用性类别标记、更广泛的无害性数据和更长对话轮数，约含110万条对话数据。目前仅开源少量示例数据，完整数据将在近期开源。· moss-003-sft-plugin-data：moss-moon-003-sft-plugin所使用的插件增强的多轮对话数据，包含支持搜索引擎、文生图、计算器、解方程等四个插件在内的约30万条多轮对话数据。目前仅开源少量示例数据，完整数据将在近期开源。· moss-003-pm-data：moss-moon-003-pm所使用的偏好数据，包含在约18万额外对话上下文数据及使用moss-moon-003-sft所产生的回复数据上构造得到的偏好对比数据，将在近期开源。协议本项目所含代码采用Apache 2.0协议，数据采用CC BY-NC 4.0协议，模型权重采用GNU AGPL 3.0协议。如需将本项目所含模型用于商业用途或公开部署，请签署本文件并发送至robot@fudan.edu.cn取得授权。

单卡部署（A100/A800）

以下是一个简单的调用moss-moon-003-sft生成对话的示例代码。可在单张A100/A800或CPU运行，使用FP16精度时约占用30GB显存：

>>> from transformers import AutoTokenizer, AutoModelForCausalLM>>> tokenizer = AutoTokenizer.from_pretrained("fnlp/moss-moon-003-sft", trust_remote_code=True)>>> model = AutoModelForCausalLM.from_pretrained("fnlp/moss-moon-003-sft", trust_remote_code=True).half().cuda()>>> model = model.eval()>>> meta_instruction = "You are an AI assistant whose name is MOSS.\n- MOSS is a conversational language model that is developed by Fudan University. It is designed to be helpful, honest, and harmless.\n- MOSS can understand and communicate fluently in the language chosen by the user such as English and 中文.

多卡部署（两张或以上3090）

此外，也可以通过以下代码在两张NVIDIA 3090显卡上运行MOSS推理：

>>> import os >>> import torch>>> from huggingface_hub import snapshot_download>>> from transformers import AutoConfig, AutoTokenizer, AutoModelForCausalLM>>> from accelerate import init_empty_weights, load_checkpoint_and_dispatch>>> os.environ['CUDA_VISIBLE_DEVICES'] = "0,1">>> model_path = "fnlp/moss-moon-003-sft">>> if not os.path.exists(model_path):...     model_path = snapshot_download(model_path)>>> config = AutoConfig.from_pretrained("fnlp/moss-moon-003-sft", trust_remote_code=True)>>> tokenizer = AutoTokenizer.from_pretrained("fnlp/moss-moon-003-sft", trust_remote_code=True)>>> with init_empty_weights():...     model = AutoModelForCausalLM.from_config(config, torch_dtype=torch.float16, trust_remote_code=True)>>> model.tie_weights()>>> model = load_checkpoint_and_dispatch(model, model_path, device_map="auto", no_split_module_classes=["MossBlock"], dtype=torch.float16)>>> meta_instruction = "You are an AI assistant whose name is MOSS.\n- MOSS is a conversational language model that is developed by Fudan University.

命令行Demo

运行仓库中的moss_cli_demo.py，即可启动一个简单的命令行Demo：

>>> python moss_cli_demo.py

此时，可以直接与MOSS进行多轮对话，输入 clear 可以清空对话历史，输入 stop 终止Demo。
