通义千问开源模型免费部署使用

首先可以参考modelScope社区给出的使用文档，已经足够全面

https://modelscope.cn/models/qwen/Qwen-7B-Chat/quickstart

但在按照文档中步骤部署时，还是有些错误问题发生，可以搜索参考的解决方式不多，所以记录下来

个人电脑部署

这里不太建议使用自己的笔记本部署通义千问模型，因为实在是太耗资源，我使用的M2芯片的MacBook Pro即使运行起来了，但模型回答一个问题都需要四五分钟的时间，内存全部占满，其他应用程序也都强制退出了。所以还是使用社区提供的免费资源，或者有更高配置的服务器来部署模型。而且期间还有各种问题，搜了很多github上的问答才解决，耗时耗力，这里就不记录了，很不推荐这种方式。

免费算力服务器

打开modelScope社区后，点击登录注册可以看到免费赠送算力的活动

注册完成后在对应模型里可以看到，随时都能启用的服务器

这里CPU环境的服务器勉强可以跑起来模型，但运行效果感人，而且配置过程中有各种问题需要修改，而GPU环境启动模型可以说是非常流畅，体验效果也很好

CPU环境启动

社区提供的服务器配置已经很高了，8核32G，但因为是纯CPU环境，启动过程中还是有些问题

安装依赖包

第一行命令不需要运行，服务器已经自带了modelscope包

只需要新建一个Terminal窗口来执行第二条命令

启动代码

直接运行文档提供的代码会报错，这里是因为纯CPU环境导致的

错误 1

解决方式

首先确保torch 2.0.1版本，然后在代码中添加这两行，即可运行

model.float()

offload_folder="offload_folder",

from modelscope import AutoModelForCausalLM, AutoTokenizer
from modelscope import GenerationConfig
import datetime
print("启动时间：" + str(datetime.datetime.now()))
tokenizer = AutoTokenizer.from_pretrained("qwen/Qwen-7B-Chat", revision = 'v1.0.5',trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("qwen/Qwen-7B-Chat", revision = 'v1.0.5',device_map="auto",offload_folder="offload_folder", trust_remote_code=True,fp16 = True).eval()
model.generation_config = GenerationConfig.from_pretrained("Qwen/Qwen-7B-Chat",revision = 'v1.0.5', trust_remote_code=True) # 可指定不同的生成长度、top_p等相关超参
model.float()

print("开始执行：" + str(datetime.datetime.now()))
response, history = model.chat(tokenizer, "你好", history=None)
print(response)
print("第一个问题处理完毕：" + str(datetime.datetime.now()))
response, history = model.chat(tokenizer, "浙江的省会在哪里？", history=history) 
print(response)
print("第二个问题处理完毕：" + str(datetime.datetime.now()))
response, history = model.chat(tokenizer, "它有什么好玩的景点", history=history)
print(response)
print("第三个问题处理完毕：" + str(datetime.datetime.now()))

运行起来之后速度实在感人，没回答一个问题都需要 5 分钟左右，还有一定概率直接启动失败

启动模型过程中会出现这种报错，点击OK重新执行就好了，可能是服务器负载太高
