About the task split when training the proposed method

[APushingBoy]

In the paper, you mentiond that MNIST and CIFAR10 are both split into 5 tasks, but I can't find the argument for the number of tasks (i.e., something like add_argument("--tasks", type=int....)) in the file options_gen_classifier.py,

but I did find an argument called --tasks in the file options.py .

Could you please tell me the reason~? Thank you.
