查看了一下，只发布了map 一个Topic。 map_updates 没有发布者。 所以是在哪里发布这个的呢

@vico1999 可以看下topic的QOS

QOS要匹配才能进行通信

发布者qos

ros2 topic info /map -v

在rviz中map组件下，点topic展开看看是否匹配

注意这里，两者并不相同

@vico1999 在 10.3中mapserver中载入地图后，rviz中不能显示 中说：

Durability: TRANSIENT_LOCAL

@vico1999 在 10.3中mapserver中载入地图后，rviz中不能显示 中说：

Reliability: RELIABLE

[vico1999]

按照这个改

我的配置和你是一样的啊，还是不能显示
