nuplan-devkit Error in config of nuplan scenario-builder

The data_root path in the nuplan scenario-builder is outdated and thus wrong.

In particular it is trying to load the trainval split directly from $NUPLAN_DATA_ROOT/nuplan-v1.1/trainval (see here). However, according to the dataset setup page, this should be $NUPLAN_DATA_ROOT/nuplan-v1.1/splits/trainval. The nuplan_mini scenario-builder uses the correct path.

Can you update this path?

Can confirm this is an issue. Just met the same one some days ago.

Hi, I wonder if this error is solved or not? I am using nuplan-devkit 1.2.2 and encounter the same problem, where the code works fine on mini set but fails on trainval set on the split dir thing.

Ok I found this can be solved by modifying the data_root to add splits in path to solve the error. hope this helps : )
