Meet error when evaluate maptrv2

[xiebinghua]

On the branch maptrv2，firstly I produce maptrv2 dataset using "python tools/maptrv2/custom_nusc_map_converter.py --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes --version v1.0 --canbus ./data"；
Then I execute this command，"bash ./tools/dist_test_map.sh ./projects/configs/maptrv2/maptrv2_nusc_r50_24ep.py ./ckpts/maptrv2/maptrv2_nusc_r50_24e.pth 1" to execute evaluation。Finally，I meet the problem mentioned as image above。
Although I followed the instructions, this error still occurred.
