Low GPU utilization but laptop hangs

Hello !
I am issue, that whenever I run any model it takes very less memory like 1.3 gb out of 6 gb ( GTX 1060 ), but volatile gpu utility is 100 %. Please tell me why my laptop is hanging even I have 5 GB of free memory.


Thanks

How many worker threads do you use with your dataloader? Can you try to reduce the num workers?

Have you stored the data in the internal hard drive or external one?
