agent.send_output失败，下游无法收到数据

[hust2018]

agent.send_output(
agent_output_name=next_node,
agent_result=cmd
)
next_node=assistant，当前节点是ra-classify，配置文件如下：
nodes:

• id: ra-terminal-input
  build: pip install -e ./agent-hub/ra-terminal-input
  path: dynamic
  outputs:

  • data

• id: ra-classify
  build: pip install -e ./agent-hub/ra-classify
  path: ra-classify
  outputs:

  • assistant
  • produce
  • camera
  • unit
  • info
  • terminal_output
    inputs:
    command: ra-terminal-input/data

• id: ra-camera
  build: pip install -e ./agent-hub/ra-camera
  path: ra-camera
  outputs:

  • camera_result

原因已定位，node在监听上游节点的数据时，agent占用，无法同时往下游节点发送数据。并发性支持还需要提高
