How to test the result?

[EchoAmor]

Hello , I have trained this code on cityscapes dataset, I got 0.69 on trainval, but I found there is nothing in the Results and Pretrained_weights directory. And the global_config.py is empty,so How to test your code ?I run the test.py but keep meeting errors:
ImportError: cannot import name 'cfg'

I will really appreciate if you can give me some advice, because your readme.txt doesn't mention it .Thank you very much!
