今天中午吃饭的时候无意间看到一则新闻说的就是复旦大学开发的MOSS也就是国产版的类chatGPT对话模型已经发布了最新版本0。0.3，目前公测期间是完全开源免费的，还是可以上手体验一下的。

官方的博客介绍在这里，首页如下所示：

 如果想要尝鲜使用的话可以访问这里，如下：

 这里是需要先填写申请问卷的，之后可以收到一个邀请码，然后点击登录注册如下：

 完成后就可以登录体验了，如下：

 我中午注册的目前还没有收到邀请码，不知道是不是申请的人太多了。。。

官方项目在这里，如下：

 厉害了，3分钟前才提交的代码。。。。。。

 看README里面比较有意思的一点就是能够文本生成图像，官方给的实例如下：

 官方也一同给出来了本地部署的方案如下：

1、下载本仓库内容至本地/远程服务器
git clone https://github.com/OpenLMLab/MOSS.git
cd MOSS


2、创建conda环境
conda create --name moss python=3.8
conda activate moss


3、安装依赖
pip install -r requirements.txt

官方介绍说的单卡部署使用FP16精度计算就需要30GB的显存，这个我是够不到这个资格的。。。

好的，以下是我为您推荐的五部科幻电影：
1. 《星际穿越》
2. 《银翼杀手2049》
3. 《黑客帝国》
4. 《异形之花》
5. 《火星救援》
希望这些电影能够满足您的观影需求。

多卡部署（适用于两张或以上NVIDIA 3090）实例如下：

>>> 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.

Star历史曲线如下：

 距今差不多正好两个月的时间吧。

等后面收到邀请码了实测一下看看效果怎么样。

当然了如果自己有本地部署的硬件实力的话可以自己把玩一下哈，项目如下：

 安装官方知道部署就行了，我就只能等线上使用体验了。
