Anyone able to successfully execute it with ade20k dataset? Please help!

Please can anyone let me know if they were able to train and evaluate (test) this code with ade20k dataset? If yes, could you kindly let me know how did you structure your dataset in the directory? (I mean what was the directory structure for the ade20k dataset, i.e. how did you arrange train, val and test dataset?)
Any help is highly appreciated. Thanks!
