RD-Agent will generate some logs during the R&D process. These logs are very useful for debugging and understanding the R&D process. However, just viewing the terminal log is not intuitive enough. RD-Agent provides a web app as UI to visualize the R&D process. You can easily view the R&D process and understand the R&D process better.
This will start a web app on `http://localhost:<port>`.
**NOTE**: The log_dir parameter is not required. You can manually enter the log_path in the web app. If you set the log_dir parameter, you can easily select a different log_path in the web app.
