Order of fine-tuning and testing on the target city in test_model.py

[HQ-LV]

Thank you for sharing the code. I have a question about test_model.py. Why, in test_model.py, is testing done first on the test set of the target city (line28-39) and then fine-tuning on the training set of the target city(line49-60)? Shouldn't it be fine-tuning first and then testing?
