self.dump_iteration_state(main_loop)

[ayanamongol]

During the training, the self.dump_iteration_state(main_loop) is not working, and the messages are as follows:

struct.error: 'i' format requires -2147483648 <= number <= 2147483647

Original exception:
error: 'i' format requires -2147483648 <= number <= 2147483647`

The parameters and log can be dumped correctly
What can I do to solve this ?
