I’ve built Caffe2 with Pytorch for Ubuntu 16.04 with cuda 9 and cudnn 7.
I’m linking both caffe2 and the GPU shared objects into this code snippet:
....

int main(int argc, char** argv) {

  caffe2::GlobalInit(&argc, &argv);

  Workspace wrk;

  auto tcpu = wrk.CreateBlob("tcpu")->GetMutable<TensorCPU>();
  std::vector<float> v(10);
  std::vector<TIndex> dims({1});
  auto val = TensorCPU(dims, v, NULL);

  google::protobuf::ShutdownProtobufLibrary();

  return 0;
}


And it segfaults with

I’m running this in a docker container with nvidia runtime. I built pytorch into the docker image and set seccomp=undefined.
