3 years ago Hello there,
what code base is that based on? The current master and in which cases does this error occur? It seems like this is a segmentation fault, in which case there is most probably an access violation (e.g., on an object that has been deleted).
Best,
Patrick
EDIT: what kind of code are you executing?

3 years ago the snippet below to determine the id of lane with agent in: agent.cpp
XodrLaneId Agent::GetCurrentLaneId() const {
auto lanecorridor = road_corridor_->GetCurrentLaneCorridor(GetCurrentPosition());
auto lane = lanecorridor->GetCurrentLane(GetCurrentPosition());
return lane->GetId();
}agent.cpp
.def("GetDistance2RoadEdge", &Agent::GetDistance2RoadEdge)I doubt that the function causes the problem when running tfa_gnn.py

3 years ago What do you use the lane_id for? At first sight, this function seems to be correct.
I would recommend you to assert that the values are not null pointers, e.g., using BARK_EXPECT_TRUE(lanecorridor != nullptr);
Do you access anything with the retrieved lane_id? But in general debugging and setting assertions should help narrowing down the problem.

3 years ago the answer to the first question is to determine Ids of lane with each agent in.

3 years ago The function looks good on first sight, but as I cannot see the full code and how you are using it, you have to try to debug it by yourself. You can also attach the python process to the c++.

3 years ago I tried to debug it but was blocked by the problem below, and it is a custom function

3 years ago As I do not have access to any of your code, I cannot help you further at this point. I would suggest for you to add as many assertions as you can to figure out where exactly it fails.
