No message and topic form blackflys camera

[tdcsu]

ros: noetic
gazebo: 11.14.0

The models are loaded successfully, but there is no topic published from the blackflys

I don't now what causes this problem

is anyone who meet with the same issue?

I' ve solved it
if you use the same configuration with me, you should add 'xacro:',the '' not included, before every self-defined xacro: macro.
that's it!!

如果你和我使用相同的配置，我已经解决了它，你应该在每个自定义的 xacro： 宏之前添加 'xacro：'，不包括 ''。 就是这样！！

你好，请问在哪些文件中添加xacro:呢
