hi,all:
when I set data loader’s num_work > 0,I got this error

it look like out of cpu memory,but when I check memory, it only use 5% memory(but lots of virtual memory)
and I use free command to checkout the memory, i found free part keep decreasing，but buffer/cache part keep increase ,and finally  job will crash
I don’t find this problem when I use pytorch 1.0.0，how can I fix it？and by the way，why it use so many virtual memory？
