hi,have you solved your problem?
I had the same problem, perhaps because of the path to pip install . I installed d4rl in a virtual environment, but when I used pip install -e . ，d4rl it was unzipped in the same directory as setup.py

check if you have installed flow and carla. d4rl can still be used if you do not install them

Hi I can't find flow, I wonder what module does flow refer to?

I think it is used to run flow-related tasks, e.g., flow-ring-random-v0. It does not matter if you do not run experiments on flow
