out of memory error

Hi, I train 3D network using 3D images and before train I face with out of memory error, so how can I solve this error?

Seems pretty clear. Get more memory. Or solve smaller problems. We don't see your code. We don't know what you are actually doing, and the error arises 22 lines into a function or script of your own creation (not shown) so how can we tell you more?
