Well, I create d a test data set which contains 13 different objects. After the training I want to use those 13 objects to test my model. I printed confusion matrix for each test data, so I need to get the name of each test data. However I used shuffle in dataloader, which called data_loader_test, when I read test data set. I used data_loader_test.dataset.training_files inside epoch loop to get the file name in each epoch. But it looks like the file name is the same order which all those test data sorted in the file. How can I get the file name order after shuffle?
