How to use a pre-trained model?

[YiFan1017]

The libcity is very nice! I met some problems. I have trained many models, however, I don't know how to use the pre-trained model to do prediction. For example, PeMSD4 dataset was used to train a model , and I just want to use the PeMSD8 to do test. I have tried the "--train false", but it seems still use the dataset to train, test and evaluate.
