谷歌的云语音 API 语音请求错误中的异常

Question

我正在尝试谷歌语音套件附带的cloudspeech_demo.py程序。我已经根据以下链接设置了Google的云语音API：https://aiyprojects.withgoogle.com/voice/#makers-guide-3-1--change-to-the-cloud-speech-api

但是我收到此错误：

src/cloudspeech_demo.py /home/pi/AIY-voice-kit-python/src/aiy/_drivers/_led.py:51: RuntimeWarning: This channel is already in use, continuing anyway.  Use GPIO.setwarnings(False) to disable warnings.
GPIO.setup(channel, GPIO.OUT)
Press the button and speak
Listening...
Traceback (most recent call last):
File "/home/pi/AIY-voice-kit-python/src/aiy/_apis/_speech.py", line 263, in do_request
return self._handle_response_stream(response_stream)
File "/home/pi/AIY-voice-kit-python/src/aiy/_apis/_speech.py", line 208, in _handle_response_stream
for resp in response_stream:
File "/home/pi/AIY-voice-kit-python/env/lib/python3.4/site-packages/grpc/_channel.py", line 348, in __next__
return self._next()
File "/home/pi/AIY-voice-kit-python/env/lib/python3.4/site-packages/grpc/_channel.py", line 342, in _next
raise self
grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with (StatusCode.UNIMPLEMENTED, GRPC target method can't be resolved.)>
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "src/cloudspeech_demo.py", line 53, in <module>
main()
File "src/cloudspeech_demo.py", line 37, in main
text = recognizer.recognize()
File "/home/pi/AIY-voice-kit-python/src/aiy/cloudspeech.py", line 47, in recognize
return self._request.do_request().transcript
File "/home/pi/AIY-voice-kit-python/src/aiy/_apis/_speech.py", line 268, in do_request
raise Error('Exception in speech request') from exc
aiy._apis._speech.Error: Exception in speech request

我在网上搜索了很多，但找不到任何有用的东西。任何帮助，不胜感激。谢谢！

自 4 月以来，API 的测试版已被弃用，并且正在被拒绝。我相信 AIY 代码已更新以解决此问题，因此希望您应该能够git pull代码，并且它应该再次工作。
