Describe the issue

When I try to use any of the commands I get an error:

google.api_core.exceptions.MethodNotImplemented: 501 Method not found.
(trace below)

I have GOOGLE_APPLICATION_CREDENTIALS configured and exported. I have enabled the API.

Commands that fail the same way:
python quickstart.py
python list_voices.py
python synthesize_file.py --text ~/video_text.txt

My directory is:
(env) jspencer@cloudshell:~/python-docs-samples/texttospeech/cloud-client$

Trace:

I'm getting this error as well. Downgrading google-cloud-texttospeech to version 0.1.0 has fixed it temporarily.

Rolling back to 0.1.0 while things get settled, sorry about that.
