program paused and need some input from the keyboard during the training process

[LeZhengThu]

Hi Bethany @BethanyL ,
I'm using the code with my own system. However, when I ran the training code, something very strange happened. When the best error was larger than the pre-defined threshold, the program was kept there and needed some input from the keyboard. After I hit space from the keyboard, it finally went to execute the next round and print too slowly improving in first 20 minutes. And when I look into the code in the function check_progress from helperfns.py, there is no 'pause' command there. So I feel this is very strange. Have you faced the same issue before?
