error performance when evaluation #175

Hi~
I tried to train fsd on waymo perception，and get the performance on validation set as follows. They are all 0.
OBJECT_TYPE_TYPE_VEHICLE_LEVEL_1: [mAP 0.749648] [mAPH 0]
OBJECT_TYPE_TYPE_VEHICLE_LEVEL_2: [mAP 0.669701] [mAPH 0]
OBJECT_TYPE_TYPE_PEDESTRIAN_LEVEL_1: [mAP 0.80301] [mAPH 0]
OBJECT_TYPE_TYPE_PEDESTRIAN_LEVEL_2: [mAP 0.73128] [mAPH 0]
OBJECT_TYPE_TYPE_SIGN_LEVEL_1: [mAP 0] [mAPH 0]
OBJECT_TYPE_TYPE_SIGN_LEVEL_2: [mAP 0] [mAPH 0]
OBJECT_TYPE_TYPE_CYCLIST_LEVEL_1: [mAP 0.744445] [mAPH 0]
OBJECT_TYPE_TYPE_CYCLIST_LEVEL_2: [mAP 0.719278] [mAPH 0]

My command is

DIR=fsd
WORK=work_dirs
CONFIG=fsd_waymoD1_1x
bash ./tools/dist_test.sh configs/work_dirs/$CONFIG.py ./work_dirs/$CONFIG/latest.pth 8 --eval fast --options "pklfile_prefix=./work_dirs/$CONFIG/results"
