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

[arcslash]

I have changed the code according to the latest commits as follows

in ~/embedded-assistant-sdk-python/googlesamples/rpi/main.py
from google.assistant.embedded.v1alpha1 import embedded_assistant_pb2
to
from google.assistant.embedded.v1alpha2 import embedded_assistant_pb2

And the lines,

ND_OF_UTTERANCE = embedded_assistant_pb2.ConverseResponse.END_OF_UTTERANCE
DIALOG_FOLLOW_ON = embedded_assistant_pb2.ConverseResult.DIALOG_FOLLOW_ON
CLOSE_MICROPHONE = embedded_assistant_pb2.ConverseResult.CLOSE_MICROPHONE

to

END_OF_UTTERANCE = embedded_assistant_pb2.AssistResponse.END_OF_UTTERANCE
DIALOG_FOLLOW_ON = embedded_assistant_pb2.DialogStateOut.DIALOG_FOLLOW_ON
CLOSE_MICROPHONE = embedded_assistant_pb2.DialogStateOut.CLOSE_MICROPHONE

but when it run the following according to tutorial following error results,

(env) pi@raspberrypi:~/embedded-assistant-sdk-python/googlesamples $ python -m rpi

Damn, I hope I didn't follow you off a cliff. I'm getting the same thing now.
Reading Metadata on the google.assistant.grpc file now about pb2 and will be trying to pick through that.
