Warning: Flow failed to import. Set the environment variable D4RL_SUPPRESS_IMPORT_ERROR=1 to suppress this message.
No module named 'flow.envs'
Segmentation Fault (“Core dumped”)

At first, it told me no module named 'CARLA' and no module named 'flow'
Then, I installed 'CARLA' & 'flow', and now it tells me no module named 'flow.envs'

Thank you very much for your attention.

It sounds like a D4RL installation issue. Running with Docker via these commands should solve it. Alternatively, you could post this stack trace as an issue to the D4RL repo to see if they have seen this before. My guess is that the segfault is unrelated to lacking the CARLA and flow environments; those are probably just installed as separate optional packages.
