python基于循环神经网络的情感分类设计与实现

项目运行

需要先安装Python的相关依赖：requests，pymysql，Django3.2.8, jieba，torch1.8.1，transformers=4.27.1，tqdm使用pip install 安装

第一步：创建数据库

第二步：执行SQL语句，.sql文件，运行该文件中的SQL语句

第三步：修改源代码中的settings.py文件，改成自己的mysql数据库用户名和密码

第四步：运行命令：python manage.py runserver 8000

第五步：打开浏览器查看http://127.0.0.1:8000

毕设帮助，指导，本源码分享，调试部署(见文末)

系统介绍：

程序上交给用户进行使用时，需要提供程序的操作流程图，这样便于用户容易理解程序的具体工作步骤，现如今程序的操作流程都有一个大致的标准，即先通过登录页面提交登录数据，通过程序验证正确之后，用户才能在程序功能操作区页面操作对应的功能。

编程人员在搭建的开发环境中，会让各种编程技术一起呈现出最终效果。本节就展示关键部分的页面效果。

总结：

主要功能是自动识别留言的情感倾向，使用了Python语言、GRU框架和MySQL数据库进行开发。在实验中，证明了该软件的准确性和实用性，可以有效地帮助用户对留言进行分类。
