驱动雷达报错
-
@763141425 虚拟机还是实体机，电脑内存硬盘配置是什么样子的，这个看起来不太相关网络问题，不过最好也提供一下网络结构
-
@小鱼 实体机，16G内存，256G硬盘，电脑通过网线连接路由器，可以PING通雷达。
输入~$ ros2 topic list
反馈：/parameter_events
/rosout
/scan
这一步都是正常的再输入ros2 topic hz /scan
雷达驱动的终端就报错了 -
@小鱼 换了两台电脑都这样
-
@763141425 报什么错呢
-
@小鱼 terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc -
