Traceback (most recent call last):
File "tools/test.py", line 11, in
from mmcv.parallel import MMDataParallel, MMDistributedDataParallel
ModuleNotFoundError: No module named 'mmcv.parallel'

Hi, this is because mmcv.parallel has been removed since mmcv version 2.0.0, you need to downgrade your mmcv version accordingly to solve this issue.
