Nuplan dataset: how to retrieve images

Hello!
I’m trying to train my model using nuplan dataset but without nuplan framework, the problem occured when I tried to retrieve image from the dataset, Image.filename suggested that the images was stored at root: ~/nuplan/dataset/mini/logname(2021.06.14.16.48.02_veh-12_04978_05337.db)/filename.jpg, but the logname directory didn’t exist! The mini directory only contains .db files instead of dicretories. Maybe I should call some functions to extract the images from .db files? I browsed the devkit but failed to find.
