Hi Mathieu,
I'm trying to run rtabmap inside a docker container with libtorch. Rtabmap without libtorch works well, but when I compile it with -DWITH_TORCH=ON it crashes with a segmentation fault. I've installed libtorch 1.13.1, cuda 11.7 and cudnn 8.9.6.50. The problem isn't of these libraries because I have other projects with libtorch and everything works well. Using gdb, when running rtabmap, the error is the following Program started...

Do you have any idea of how to solve it? Thanks in advance. |

That crash doesn't look like related to pytorch, though if it is crashing only when libtorch is linked to rtabmap, maybe libtorch is using slightly different libraries than the system's ones (maybe a different version of llvm?). Is libtorch built from source?
