demo/Mask_R-CNN_demo.ipynb bug

❓ Questions and Help

ubuntu 18.04
cuda 9.0
cudnn 7.1.3

I test the demo/Mask_R-CNN_demo.ipynb on the ubuntu. Every time the code come to the last block:
predictions = coco_demo.run_on_opencv_image(image), the kernel will reboot without any erro infomation. I check the code step by step, and find out the No.200 : predictions = self.model(image_list) in the predictor.py is the source of the problem.
I can't solve it by myself, anyone could give me some suggestion.
Thanks.

Hi,

Can you try the webcam demo? It should fail as well, but with a more meaningful error message.

Also, what is your gcc version?
You need to have at least gcc version 4.9. Check the TROUBLESHOOTING section of the README for more details

thanks for your reply.
gcc 4.8, I downgrade to 4.8 for installing the cuda9.
I will check again with the gcc 4.9
thanks again.

Cool!

So, as this seems to be the same error as the one explained in https://github.com/facebookresearch/maskrcnn-benchmark/blob/master/TROUBLESHOOTING.md#segmentation-fault-core-dumped-when-running-the-library, I'll close this issue.

Please let me know if you still have issues.

You have catch the key to the problem.
gcc 5.5 is ok. Both of gcc4.8 and gcc7 don't work well.
thanks a lot.
