speech_streaming tests do not pass

[raphael0202]

After installing the required dependencies, the tests of the streaming Speech API don't pass. The live speech recognition (speech_streaming.py) also don't work: no error is raised, but no response from the Google Cloud server is received, even if Streaming RecognizeRequest are sent regularly.

We merged a version of the sample that was using an internal-only version of the API. We've reverted that change. Can you try this again with the latest code?

[theacodes]

(closing, but feel free to respond and I'll re-open if needed)

[raphael0202]

An import error occurs, because in speech_streaming.py, the module name was not corrected during the import.
from google.cloud.speech.v1beta1 import cloud_speech_pb2 as cloud_speech
instead of google.cloud.speech.v1

After fixing this ImportError, I get another one:

[theacodes]

I can't debug any further, @xinjiez @jerjou any ideas?

(jerjou is ostensibly out until mid-next week, but ccing him just in case)

[theacodes]

@puneith as well.

[theacodes]

@raphael0202 does the sample itself work if you run it directly?

[raphael0202]

@jonparrott I have the same error if I run speech_streaming.py directly:

Traceback (most recent call last):

[theacodes]

Great, just making sure. And you are on the latest HEAD of master, right?

[xinjiez]

Could you please do this
pip install -r requirements-speech_grpc.txt

and use google.cloud.speech.v1 instead of google.cloud.speech.v1beta1 and see if it fixes the problem?

Because we rollback please refer to the original README and run the instructions again. Sorry for the inconvenience.

Thanks.

[raphael0202]

Yes, latest HEAD on master branch. Did you manage to reproduce the bug?
By the way, I don't know if you previously noticed this info in my previous message, but I had to manually fix an ImportError in speech_streaming.py:

Traceback (most recent call last):
File "speech_streaming.py", line 22, in
from google.cloud.speech.v1 import cloud_speech_pb2 as cloud_speech
ImportError: No module named v1

[raphael0202]

Ok, I used pip install -r requirements-speech_grpc.txt

But now everything works, both the tests and the script.

[theacodes]

It did install grpc-google-cloud-speech-1.0.4. So is this resolved?

[raphael0202]

Yes indeed. And yes this is resolved. Thanks!
