无法在 Pepper 的 Choregraphe 中导入 python 模块

【问题标题】：Cannot import python module within Choregraphe on Pepper无法在 Pepper 的 Choregraphe 中导入 python 模块
【发布时间】：2017-06-08 13:48:20
【问题描述】：

我已经按照official Google tutorial，通过SSH在Pepper机器人上安装了谷歌语音API。

为了测试它，我创建了一个文件 speechTest.py，我在其中导入 API，如下所示：

from google.cloud import speech

这行得通！到现在为止还挺好。但是当我想在 Choregraphe 的 Python 框中做同样的事情时，问题就出现了；当我收到错误提示时：

[ERROR] behavior.box :createPythonModule:0
_Behavior__lastUploadedChoregrapheBehaviorbehavior_11325017632:/GoogleSTT_7:
User class evaluation failed with the error:
<class 'pkg_resources.DistributionNotFound'>
google-cloud-speech

我尝试了raised in the community 的解决方案，但没有成功。当我从 Python in Choregraphe 框中打印 sys.path 时，我得到：

[WARN ] behavior.box :onLoad:15 _Behavior__lastUploadedChoregrapheBehaviorbehavior_1811402208:/GoogleSTT_7:

这表明它应该找到 Google 包。我怎么解决这个问题？我不知道如何将 Google Speech API 导入 Choregraphe 项目。

编辑：当我在机器人的本地 Python 文件中输出 sys.path 时，我得到了这个：

/var/persistent/home/nao
/home/nao/.local/lib/python2.7/site-packages/pip-9.0.1-py2.7.egg
/usr/lib/python27.zip

【问题讨论】：

  • 所以你的意思是它可以在 shell 命令中的 python 脚本中工作，而不是 chroregraphe ？ 1.无论您从哪里启动python解释器，它是否都可以从shell命令工作。 2. 你能告诉我们你是否安装了包，所以我们可以从 sys.path 中检查它是否可见 3. 你是否在安装包后重新启动 naoqi 一次？有时在 .local 中添加新文件夹需要重新加载 naoqi 解释器......祝你好运......
  • 嗨@AlexandreMazel，1) 是的，我可以在不同的位置执行python 脚本。 2) 当我运行 `pip show google-cloud-speech` 时，我得到Location: /var/persistent/home/nao/.local/lib/python2.7/site-packages 3) 我已经重启了 Pepper 几次，但都没有运气。我在我的问题中添加了来自本地 python 文件（看起来要短得多）的sys.path 的输出。

【解决方案1】：

我相信在项目中使用默认未安装在机器人上的 python 库的最佳方法是将其添加到项目中。 这样，当您的软件包安装在机器人上时，您始终可以确保安装了您的依赖项。它可能并不理想，但更可靠的解决方案。

勘误： 实际上，如果您在项目（python 文件）中使用 python 编写服务，则可以通过将依赖项放在 python 文件旁边来发送依赖项。 但是行为不能使用它们，你确实需要安装它们。

但是您可以做的是在您的项目中使用 google API 和您的 behavior.xar 中的 python 编写一个服务，启动该服务，使用它来执行您需要的操作，并在退出时停止该服务。 （理想情况下，您的服务可以在行为停止时自行停止）
