如何修复 ALDialog Python 脚本 NAOqi 错误

问题描述

我正在尝试使用 ALDialog 模块与 choregraphe 模拟 NAO6 机器人进行虚拟对话。我有以下脚本：

import qi
import argparse
import sys

def main(session):
    """
    This example uses ALDialog methods.
    It's a short dialog session with two topics.
    """
    # Getting the service ALDialog
    ALDialog = session.service("ALDialog")
    ALDialog.setLanguage("English")

    # writing topics' qichat code as text strings (end-of-line characters are important!)
    topic_content_1 = ('topic: ~example_topic_content()\n'
                       'language: enu\n'
                       'concept:(food) [fruits chicken beef eggs]\n'
                       'u: (I [want "would like"] {some} _~food) Sure! You must really like $1 .\n'
                       'u: (how are you today) Hello human,I am fine thank you and you?\n'
                       'u: (Good morning Nao did you sleep well) No damn! You forgot to switch me off!\n'
                       'u: ([e:FrontTactilTouched e:MiddleTactilTouched e:RearTactilTouched]) You touched my head!\n')

    topic_content_2 = ('topic: ~dummy_topic()\n'
                       'language: enu\n'
                       'u:(test) [a b "c d" "e f g"]\n')

    # Loading the topics directly as text strings
    topic_name_1 = ALDialog.loadTopicContent(topic_content_1)
    topic_name_2 = ALDialog.loadTopicContent(topic_content_2)

    # Activating the loaded topics
    ALDialog.activatetopic(topic_name_1)
    ALDialog.activatetopic(topic_name_2)

    # Starting the dialog engine - we need to type an arbitrary string as the identifier
    # We subscribe only ONCE,regardless of the number of topics we have activated
    ALDialog.subscribe('my_dialog_example')

    try:
        raw_input("\nSpeak to the robot using rules from both the activated topics. Press Enter when finished:")
    finally:
        # stopping the dialog engine
        ALDialog.unsubscribe('my_dialog_example')

        # Deactivating all topics
        ALDialog.deactivatetopic(topic_name_1)
        ALDialog.deactivatetopic(topic_name_2)

        # Now that the dialog engine is stopped and there are no more activated topics,# we can unload all topics and free the associated memory
        ALDialog.unloadTopic(topic_name_1)
        ALDialog.unloadTopic(topic_name_2)


if __name__ == "__main__":

    session = qi.Session()
    try:
        session.connect("tcp://desktop-6d4cqe5.local:9559")
    except RuntimeError:
        print ("\nCan't connect to Naoqi at IP desktop-6d4cqe5.local(port 9559).\nPlease check your script's arguments."
               " Run with -h option for help.\n")
        sys.exit(1)
    main(session,"desktop-6d4cqe5.local")

我模拟的机器人有 desktop-6d4cqe5.local 作为 IP 地址，它的 NAOqi 端口在 63361 上运行。我想在 python 脚本中运行 choregraphe 之外的对话框，并且只能使用 choregraphe 中的对话框测试它。当我运行上面的python文件时，我得到了：

Traceback (most recent call last):
  File "C:\Users\...\Documents\...\choregraphe_codes\Welcome\speak.py",line 6,in <module>
    import qi
  File "C:\Python27\Lib\site-packages\pynaoqi\lib\qi\__init__.py",line 93
    async,PeriodicTask)
    ^
SyntaxError: invalid Syntax
  

我无法弄清楚问题，因为网上资源不多，而且机器人的文档有点难以理解。

请帮忙，谢谢。

解决方法

您正在使用高于 3.5 的 Python 版本运行脚本，现在将 async 视为关键字。

NAOqi 仅支持 Python 2。 尝试使用 python2 显式运行您的脚本。
