Pubsub: 'thread_name_prefix' error

[kerighan]

Hi !

I have installed and upgraded google cloud (Im' working on Python 2.7), but whenever I try to create a SubscriberClient object, I get the following error : TypeError: init() got an unexpected keyword argument 'thread_name_prefix'

This happens on my machine but also on Google Compute engines. This error comes from the fact that the concurrent.futures.ThreadPoolExecutor class does not have a "thread_name_prefix" argument.

Do you have a solution for my error ? Can you reproduce it ? Thank you very much for your help !

Can you please provide the complete traceback? Also, the output from pip freeze?

The release notes for google-cloud-pubsub 0.29.3 note (in the "Dependencies" section):

Upgrading google-api-core dependency to latest revision (0.1.2) since we rely on the latest version of the concurrent.futures backport to provide the thread_name_prefix argument for thread pool executor (#4521, #4559).

Please try in a fresh virtual environment, or else upgrade the dependencies in your current environment.
