nonetheless, this project is amazing! looking forward to where it goes in the future

dabreegster commented on May 5, 2024

Thanks for reporting! I'm having trouble reproducing either problem, but both are pathfinding breaking.

@mdesantis, from your logs, the spawn agents at intersection works a few times, but then breaks somewhere. Is that right? Can you tell me what IntersectionID you're hovering over when it breaks? (The bottom bar shows this. I'll add this to the logs to make it easier to debug in the future.)

@b-camacho, I'm very confused how this is happening. You're using a binary release? I'll add some better errors to figure this out.

b-camacho commented on May 5, 2024

@dabreegster Thanks for looking into it!
I'm compiling from source, commit 77050761. Could not run binary due to #17, but I doubt these are related.

from abstreet.

dabreegster commented on May 5, 2024

@b-camacho, would you mind pulling and running again? You should see an error like ".... not in NodeMap". Somehow the contraction hierarchy built to speed up pathfinding isn't including one of the path endpoints.

Sure enough, there it is

Exact repro steps are:

run in either debug or release
open sandbox
click any intersection
choose "spawn agents around this intersection"
Maybe it's relevant that instantiating scenarios causes the same panic.

Ah, those nodes are from e4a3430. Since you're running from source, I think when you ran data/grab_seed_data.sh, you got an old set of maps. I updated the data there about an hour ago. If you grab_seed_data.sh and run again, everything should be fine.

Prevention in the future: I need to make sure to upload new seed data as soon as something changes. I'll look into changing the map building pipeline to put checksums of files under version control, so it's very obvious when I need to upload again.

#25 and #26 were the same issue and were fixed by grabbing the new map data, so closing this bug too. I'll make sure to keep the data updated for people building from source. Let me know if you hit any other problems! (Still looking into the Linux binary compatibility problem)
