Breaking change for google-api-python-client 1.9.3 - AttributeError: module 'google.api_core' has no attribute 'gapic_v1'

Question

Is anyone else getting the above?

I can't for the life of me figure out why it's complaining about the google.api.core module. This was working for me last week, but since updating the google-api-python-client it's now not, and I'm struggling to get back to a working version.

Google-api-core 1.17.0 suffers from another regression (fixed in the most recent version) that breaks the streaming pull, thus the users that use that feature should instead temporarily pin google-api-core to an even older version, e.g. 1.16.0. For More detailed please refer to link.
