AttributeError: 'module' object has no attribute 'OperationsStub'

In which file did you encounter the issue?

speech/cloud-client/quickstart.py

Did you change the file? If so, how?

No, straight from cloning the project

Describe the issue

Python 2.7.6

Followed the Readme instructions (https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/speech/cloud-client) to clone the python samples and and installed dependencies.

The only requirements.txt that was ran was from speech/cloud-client/requirements.txt

However, after setting up authentication by running export GOOGLE_APPLICATION_CREDENTIALS=, I ran the command python quickstart.py.

Following error was received:
$ python quickstart.py
Traceback (most recent call last):

The example seems to work now under Python 2.7. The required version of google-cloud-speech was updated on September 29 in PR #1702, which might have fixed the issue. Please reopen this issue if the problem is still there with the latest version on Github. Thanks.
