Steps to reproduce the issue:

• Please use bullet points and include as much details as possible:
  1. (From the ${APOLLO_ROOT_DIR} directory)
  2. git checkout -t origin/r5.5.0
  3. ./docker/scripts/dev_start.sh
  4. ./docker/scripts/dev_into.sh
  5. touch WORKSPACE
  6. bazel build //modules/perception/lidar/tools:offline_lidar_obstacle_perception

I want to use LiDAR 3D Object Detection in perception module. I followed this reply (https://github.com/ApolloAuto/apollo/issues/13445#issuecomment-782576120) but it doesn't work.

Error occurs like this.

What should I do now???
