In the /DAIR-V2X/v2x/dataset directory, when I run: python dair_v2x_for_detection.py, I observe that...

Traceback (most recent call last):

There is a circular import in the code：dair_v2x_for_detection.py -> base_dataset.py -> dataset.__init__.py -> dair_v2x_for_detection.py.

You should not directly run python dair_v2x_for_detection.py. You should follow get_started to use the framework.
