Nv card crash down while training my deep learning model

nvidia-bug-report.log.gz (384.3 KB)
My card is 1080Ti, os is ubuntu 18.0.4. Anyway, I have tried two different models deploying on tensorflow and pytorch separately.
Both training and predicting will make the card crash down: screen is black, model isn’t running for after I reboot pc, there isn’t any predicting output. However, os is working fine cause the music app is still running.
Thank you guys if anyone could help.
