这个结构表明你的ROS 2 Python包py_pubsub已成功创建,并且构建类型为ament_python。 综上所述,通过执行ros2 pkg create --build-type ament_python py_pubsub命令,你已经成功创建了一个名为py_pubsub的ROS 2 Python包。现在,你可以开始在该包中添加你的Python代码和ROS 2接口了。

Then, we install the scripts/py_node.py file. We put this file in the install lib/ folder, which is the same folder as for ROS2 Cpp nodes. Thus all Cpp/Python executables will be at the same place. For any new Python script you need to install, just add a new line here. After ...

My guess is that number of created sub-process is piled up when we keep launching new process and it would cause ros2 rclpy buffer overflow(probably while threading) since the number of created sub-process is inherited with "fork" option to the sub-processes. On the other hand, brand new...
