/home/wth/project/lidar/proto/data_load.proto: File does not reside within any path specified using --proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).

这是一个编译错误，提示你没有指定正确的 --proto_path 参数。这个参数是用来告诉编译器在哪些路径下查找 proto 文件。你需要检查一下你的编译命令中是否指定了正确的 --proto_path 参数，并且该参数是否包含了 data_load.proto 文件所在的路径。另外，你还需要确认一下 data_load.proto 文件是否存在，并且文件名是否正确。如果以上步骤都没有问题，那么你可能需要检查一下编译环境是否正确配置。
