Several questions

[yusupeng]

Dear teacher, I have read your paper and downloaded the code. I have some questions.

1. train_ssl.sh mentioned in readme was not found in the project.

2. Would you like to know why each train instruction of sh file needs to be entered five times?

3. Can the project use other data sets like road extraction data sets for experiments? What does scribbles_generator.py do？
