Hi @Manivannan Murugavel, actually its a nice tutorial and helped me lot to train YOLO v2 for custom dataset. While Training, it throws a “Segmentation fault (core dumped)” issue . I followed what you said in the tutorial, additionally i installed Opencv, supported lib files for Opencv and OpenMP for Multiprocessing. I am using Ubuntu 16.04 Server Edition. Kindly help me to resolve this issue.
