( running Ubuntu 18.04 GTX 1080Ti CUDA 10.1 NVIDIA 430.26)

The first run is very good. The second time a Segmentation fault (core dumped) occurs.

TensorRT inference engine settings:

Any help?

Hey @shift093,

I'm working on a fix for this. In the meantime, removing your cached engines (by deleting your .buf files in the /engines folder) can solve the problem for a few runs.

@GLBurnett It works! Btw it works on my tx2 ,and "engine file" works very well. If there is further news, please inform me again.Thanks!

Hello, is there any update on this issue? I am still facing the segmentation fault whenever I re-run and I have to remove the .buf file. Strangely this occurs on the Jetson Xavier but not my laptop where I can re-run many times.
