bev_pool/bev_pool_ext.cpython-38-x86_64-linux-gnu.so ERROR

[DonghoonPark12]

When trying to test,

$./tools/dist_test_map.sh ./projects/configs/maptr/maptr_tiny_r50_24e_t4.py ./ckpts/maptr_tiny_r50_24e_t4.pth 1

The error below appeared. Does the following mean that mmdet3d is not installed properly?

  File "/home/user/DATA_LOCAL2/MapTR/mmdetection3d/mmdet3d/ops/bev_pool/bev_pool.py", line 3, in <module>
    from . import bev_pool_ext
