System information

• **OS Platform and Distribution :Linux Ubuntu 20.04
• Apollo installed from (source or binary): source
• Apollo version (3.5, 5.0, 5.5, 6.0): 8.0.0
• Output of apollo.sh config if on master branch:

Steps to reproduce the issue:

• Please use bullet points and include as much details as possible: 我在进行Apollo与Carla的联合仿真。我现在想要创建msf定位需要的local_map，使用cyber_recorder record -c /apollo/sensor/gnss/odometry /apollo/sensor/lidar128/compensator/PointCloud2录制了record文件，然后运行脚本bash /apollo/scripts/msf_simple_map_creator.sh /apollo/record_file/0407/ /apollo/modules/localization/msf/params/velodyne_params/velodyne64_novatel_extrinsics_example.yaml 31 /apollo/records/mymap产生local_map，但是一直报这个错误：Can't find the file: /apollo/records/mymap/lossy_map//map/000/north/31/00000000/00000000 我找到了报错的位置， https://github.com/ApolloAuto/apollo/blob/3ecbf3006d9a1c3d832c3d925dc838d2d762c571/modules/localization/msf/local_pyramid_map/base_map/base_map_node.cc#L161-L175 但是文件是存在的 我也尝试了其他的Apollo版本，但都是这个问题。 另外，我想知道velodyne64_novatel_extrinsics_example.yaml 这个参数是根据什么确定的；31是Carla地图的zone_id，Apollo的是10，我该用哪个？ 我已经被can't find the file这个问题困扰了很久，任何变化对我来说都是好的！希望大佬解惑，谢谢！

我觉得应该是一开始没有这个文件，然后打印了这个日志，之后就创建了这个文件；而不是有这个文件，但是它找不到。

按我的理解，这个报错信息没什么影响，只是个普通的日志。
