自己做剧本网站网络营销推广的优势

我们需要在现有的代码基础上增加网络搜索功能，并在大模型无法提供满意答案时调用网络搜索。以下是完整的代码和文件结构说明，我们创建一个完整的项目结构，包括多个文件和目录。这个项目将包含以下部分：

主文件 (main.py)：包含GUI界面和模型加载、训练、评估等功能。
网络请求模块 (web_search.py)：用于从互联网获取信息。
日志配置文件 (logging.conf)：用于配置日志记录。
模型文件 (xihua_model.pth)：训练好的模型权重文件。
数据文件 (train_data.jsonl, test_data.jsonl)：训练和测试数据文件。
项目结构：包括上述文件和目录。

说明
main.py：主文件，包含GUI界面和模型加载、训练、评估等功能。
web_search.py：用于从百度搜索信息的模块。
logging.conf：日志配置文件，用于配置日志记录。
data/：存放训练和测试数据文件。
logs/：存放日志文件。
models/：存放训练好的模型权重文件。
通过以上结构和代码，你可以实现一个具有GUI界面的聊天机器人，该机器人可以在本地使用训练好的模型回答问题，如果模型中没有相关内容，则会联网搜索并返回相关信息。
