Yeah sure, I just saw your message. Each column shows some statistics, the columns are defined with the separators |. Forget the first one, it just shows the iteration number of the training and some other stuff. Starting from the second column | we have 4 numbers. All of them indicate a loss. The 1st is the rpn (region proposal network) loss, the 2nd is the mask loss, 3rd is the bounding box loss, 4th is the label/class loss. Let me know if that makes any sense or if you need any more info. Thanks again!
