Description

When I trained the face detection model, I found that if there are more than one GPU visible, the training would encounter error：

*** Aborted at 1544374351 (unix time) try "date -d @1544374351" if you are using GNU date *** PC: @ 0x0 (unknown) *** SIGSEGV (@0x0) received by PID 32735 (TID 0x7f5aa0848700) from PID 0; stack trace: *** @ 0x7f5aa0440390 (unknown) @ 0x0 (unknown)
