I encountered a problem while executing download_contents.py

When executing download_contents.py, the system became unresponsive without any error logs or prompts.

Additionally, could you provide a tutorial outlining the installation steps for this model, the installation and support of the required companion models? Is it possible to obtain instructions for using this model and performing trend analysis and investment recommendations for a specific stock after training the model with data?"

当执行download_contents.py时，系统停止了响应，无报错日志和提示。

另外一个问题，可否出一个教程，介绍一下这个模型的安装步骤、需要的配套模型的安装和支持，能不能下这个模型的使用方法，
