training error, cannot start about fcos

[tianzhi0549]

@song6299 I suggest that you try to train it with a single GPU to see what happends, using the following command line.

python tools/train_net.py \
    --skip-test \
    --config-file configs/fcos/fcos_R_50_FPN_1x.yaml \
    DATALOADER.NUM_WORKERS 2 \
    OUTPUT_DIR training_dir/fcos_R_50_FPN_1x \
    SOLVER.IMS_PER_BATCH 1

Thank you for your reply, I have run that command line, now raise error as following:
2019-05-15 15:47:24,208 maskrcnn_benchmark.trainer INFO: Start training
Segmentation fault
What is the reason of segmentation fault? Another question is I install the environment as INSTALL.md, why the version of pytorch is 1.1.0, does it will influence the experiment?

@song6299 Please check https://github.com/tianzhi0549/FCOS/blob/master/TROUBLESHOOTING.md. It might result from your lower GCC version. Pytorch 1.1.0 should not be the reason.

Thanks, I will install higher gcc~~~
