These are lane change routes, we don't use scenarios for them. We use an no_scenario.json file which looks like this:
{
"available_scenarios": [
{
}
]
}
I'm currently trying to recreate your dataset locally
Trying to recreate the dataset with 1 computer might be too slow. When we run these 3000 routes we parallelize them across ~100 GPUs in our compute cluster. This gives almost linear speedup in dataset generation as the routes are all independent.
I'm basing all this on the assumption that the dataset is recreatable
It is, up to the specific routes that crashed during parallelization. The CARLA traffic manager is also nondeterministic (and can't be seeded in this version of the simulator), so you will get a similar dataset but not the same one.
That clears the confusion, thank you very much! And yes, my poor laptop wouldn't be too happy about creating this dataset itself, this all happens on our cluster.
Really appreciate the quick response!
Hi, first of all thank you for all the great work on this project.
I'm currently trying to recreate your dataset locally using the instructions in the README and dataset/README, but I have some questions that I'm hoping you can answer. I'm basing all this on the assumption that the dataset is recreatable (not pixel-perfect, but same frame count and folder structure) using only the scenarios and routes in
leaderboard/data/training
and with the scripts intools/dataset/
, so please let me know if I'm missing something there.leaderboard/data/training/scenarios
?leaderboard/scripts/datagen.sh
, it is required to set bothROUTES
andSCENARIOS
. However, thell, lr, rl, rr
routes inleaderboard/data/training
have no corresponding scenario, how do you run the script to generate data using those routes?Thanks again!
