Killed during training processing

[1998LIN]

Hello. When I run the experiments/fgfa_rfcn/fgfa_rfcn_end2end_train_test.py --cfg experiments/fgfa_rfcn/cfgs/resnet_v1_101_flownet_imagenet_vid_rfcn_end2end_ohem.yaml with python3, I meet the problem below. My workstation is configured with an NVIDIA GTX 2080 Ti (32G). Looking forward to your reply. Thank you.

I've tried to change KEY_FRAME_INTERVAL= 5, but it still doesn't work.
Does anyone face the problem?
