python - 无法在 Aldebaran Nao 上运行代码

Question

我在文件 say.py 中使用 Python SDK 编写了一个简单的程序。 Aldebaran Nao 连接到 IP 172.26.96.164 的网络

from naoqi import ALProxy
pr = ALProxy("ALTextToSpeech", "172.26.96.164", 9559)
pr.say("Hello, You are awesome !")

代码运行良好。但是当我在电脑上启动本地版Naoqi

> & 'C:\Program Files (x86)\Aldebaran\Choregraphe 1.12.5.3\bin\naoqi-bin.exe'

say.py 的代码停止运行并出现以下错误。

PS C:\Users\admin\Desktop\nehchal> python say.py
[INFO ] Starting ALNetwork
[ERROR] Connection failed ! Port 54010 is already in use. Are you already running NaoQi? Use --broker-port option to specify a different port.
[INFO ] Stopping ALNetwork
[INFO ] Exit
Traceback (most recent call last):
  File "say.py", line 2, in <module>
pr = ALProxy("ALTextToSpeech", "172.26.96.164", 9559)

this = _inaoqi.new_proxy(*args)
RuntimeError:   ALBroker::runBroker
    Port 54010 is not free. Another broker is using this port.

有人可以解释一下这个错误到底意味着什么吗？如何知道谁在使用这个端口？如何释放端口或如何使用备用端口？

Answer 1

查看naoqi命令行选项:

• -p [ --broker-port ] arg (=9559) 服务器端口，默认为 9559

• --pport arg (=0) 父代理的端口，默认为 no 父级 (0)。
