How to use multi GPU to train？ #62

Open zmf2022 opened 4 months ago

lizhan17 commented 4 months ago

current code does not support mulit gpu training. if you meet gram issue, you can use int8 training. by adding "--gtisint8 1"

if you have large cpu memory (>40 GB), lazying loading is supported "--data_device cpu"

Hi @lizhan17, does using int8 training cause any performance degradation?

performance should be very close. int8 training just store ground truth image as int8 on gpu.
