which parameter is the test file name used by predict.py

[greatofdream]

I saw the demo predict.py use settings["path_to_test_x"] in class Experiment:get_test_x, is this mean the test file name will set as the value of settings["path_to_test_x"] and be used for reading test data?

If above is right, it's very strange to couple this parameter into code deeply.

Yes, settings["path_to_test_x"] is the file with the data you have available for the prediction. In the evaluation.py code, all test files are iterated over and the value of settings["path_to_test_x"] is changed in each iteration (see here).

The goal is then to predict the 288 timesteps following the information in this file.
To access the data, in your predict.py file, you can do something like:

df = pd.read_csv(settings["path_to_test_x"])

(note that I'm not involved with the oragnization of the competition.)
