Segmentation fault (Core dump) when using GPU

(Elliothe) #1

Recently, the GPU driver on the server is updated to 390.12 by the IT support, then I also update the CUDA9 and cudnn library corresponding. However, since then I started to get segmentation error once I call .cuda() function. I attach the following stack traces. The example I use is the official mnist example:

did you reinstall with the cuda 9 version?

Yes, I install a local anaconda 3 and install the cuda 9 version pytorch.
