About visualization

[HuangZhe885]

It is an excellent work and a great contribution to the community, thank you for making it open-source. I have two questions：

• First, I successfully ran the ‘Run close-loop evaluation’, but I am not quite sure about the meaning of the files under the results directory—how should I interpret the results and how can I visualize them?

• Second, how can I retrain the model, and where can I find the dataset?

Thanks again
