ImportError: attempted relative import with no known parent package

[zaper4life]

Couldn't find anyway to make it work, couldn't find support online, I'm a newb who want to play with experts, if you can help me to get it to work I'll love it.

After running:

python -m pushtotalk --device-id 'my-device-identifier'

I've encountered following error:

pushtotalk.py", line 38, in
from . import (
ImportError: attempted relative import with no known parent package

Which python version are you using? Python 3?

[zaper4life]

I ran:
brew install python python3
it completed successfully :)

Than I ran:
python --version
But got:
Python 2.7.10

I install python launcher from a downloaded dmg and it version appear to be:
3.6.4

When I'm in the environment the version changes to 3.6.4 as well:

(env) ISRTLVMAC13:grpc Fleker$ python --version
Python 3.6.4

[Fleker]

Do you have access to python3 in the terminal? Can you run python3 --version? What if you run python3 -m pushtotalk --device-id 'my-device-identifier'?

[zaper4life]

Nope, not it, I'll attach my actions.

@proppy do you know more about this bug? It appears to be something to do with the Python imports here.

I've pasted the previous logs below for easier access

This seems like an issue with python 3.6

[proppy]

I can reproduce the issue when trying to run with python3.6 -m pushtotalk

(env) grpc 👺  python3.6 -m pushtotalk
Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    from . import (
ImportError: attempted relative import with no known parent package

The other documented way to run the package work as expected:

(env) grpc 👺  googlesamples-assistant-pushtotalk
INFO:root:Connecting to embeddedassistant.googleapis.com
Press Enter to send a new request...
INFO:root:Recording audio request.

This also work:

(env) grpc 👺  python3.6 -m googlesamples.assistant.grpc.pushtotalk
INFO:root:Connecting to embeddedassistant.googleapis.com
Press Enter to send a new request...
INFO:root:Recording audio request.

We still have an issue when running the sample directly from the file.

(env) grpc 🍡  python pushtotalk.py
Traceback (most recent call last):
  File "pushtotalk.py", line 38, in <module>
    from . import (
ImportError: cannot import name 'assistant_helpers'

I think this is related to this python 3.6 change that change the raised error from SystemError to ImportError.

So this simple patch should work:

diff --git a/google-assistant-sdk/googlesamples/assistant/grpc/pushtotalk.py b/google-assistant-sdk/googlesamples/assistant/grpc/pushtotalk.py
index 5b2b4ba..c2706a9 100644

We could also re-check if the boilerplate (introduced in 22db071) is indeed necessary by testing the different way to run the sample with all python versions.
