How to reduce memory usage

[xuwuzhou]

My device: cpu: i710700+32GB memory+2080ti(10GBmemory)
My problem: when I run big dataset, such as kitti Seq,00(the number of images is 4541), 32GB memory is out of use. I think there must be a problem, and I locate the specific function that occupies a large memory in MaskRCNN.py(Line 64, function GetDynSeg). Because I am not familar with MaskRCNN, I can not debug more.

What can I do to reduce the usage of memory?

Thanks for your reply
