How can we define a list of integers?

[llan-ml]

In many cases, we need pass a list integers to a program, such as a list containing the number of units per layer in a neural network.

For now, with DEFINE_list, we have to manually change the type of each element from string to int. And DEFINE_multi_integer may lead to a very long command line string since the argument name needs to appear multiple times.

Is it possible or easy to declare a default type of each element for DEFINE_list, like argparse?

We currently don't support such flag type, and you need to use DEFINE_list and use a helper function to do the conversion as you mentioned.
