How to change the size of the dataset?

[CaffreyR]

Hi @ShengdingHu , thanks for sharing the code. May I ask that how to change the size of dataset. It seems that that the COPA have 400 train dataset, 50 val dataset, 50 test dataset. I want to change a little bit of the size, but change the "max_train_samples","max_val_samples","max_test_samples" seems not to work.
