No changes to file.

Describe the issue

Getting an error when the file is run after setting the environment variable GOOGLE_APPLICATION_CREDENTIALS. I'm using Python 2.7.11 on Windows 8.1.

Stack trace:

C:\test>python transcribe_streaming.py

@jerjou

Ah I see, this whole sample needs to be updated to use google.auth.

Maybe @jerjou or @ryanmats can handle it?

We should essentially replace make_channel with http://google-auth.readthedocs.io/en/latest/reference/google.auth.transport.grpc.html#google.auth.transport.grpc.secure_authorized_channel

@jonparrott

Thanks @jonparrott for the direction. I'm trying adding google.auth to the sample myself. Is there any other sample that is up to date with google.auth?

Not one that users grpc directly.

In my attempt at getting google.auth added to transcribe_streaming.py, I modified the code to use google.auth as given in here.

Installed google-cloud-speech-v1 using pip install grpc-google-cloud-speech-v1 before running the file. But getting the following error.

C:\>python transcribe_streaming-new.py
Traceback (most recent call last):
  File "transcribe_streaming-new.py", line 256, in <module>
    main()
  File "transcribe_streaming-new.py", line 231, in main
    with cloud_speech.create_Speech_stub(
AttributeError: 'module' object has no attribute 'create_Speech_stub'

When I looked at the attributes of cloud_speech_pb2, I can't see the create_Speech_stub. Instead beta_create_Speech_stub is what it has. I have tried calling this method. I don't know if it is good to use this beta method though.

>>> from google.cloud.speech.v1 import cloud_speech_pb2 as cloud_speech
>>> dir(cloud_speech)

However, I'm getting following error now.

C:\>python transcribe_streaming-new.py
Traceback (most recent call last):
  File "transcribe_streaming-new.py", line 256, in <module>

Exception AttributeError: "'Channel' object has no attribute '_connectivity_state'" in <bound method Channel.__del__ of <grpc._channel.Channel object at 0x0000000003E37898>> ignored

What could be the reason?

@chan71

@chan71 seems it was a more significant change than anticipated: We have a PR out to fix this here: #724

@jonparrott

Works like a charm. Appreciate your fast turnaround in fixing this @jonparrott and team

Happy to help!
