mask RCNN training takes too much time

[jackhyggrh]

hi,
im trying to train my custom dataset of over 1500 images for a multiple class object detection and segmentation but the training is
taking too much time i left it for over 7 hours to train. At this point, it is difficult to know what went wrong as it does not show any error message. Therefore, I would like to ask for help to resolve this situation . The training completes up to 100 epochs before repeating the same operation as shown in the screenshot below. would really appreciate any help.
Thanks.
