Aiyprojects-raspbian: Error when executing src/examples/voice/assistant_grpc_demo.py

[vishwapinnawala]

newbie here Help!!! Tried Re enabling Assistant API and i tried installing AIY os again and again 3 times no luck

Traceback (most recent call last):

@vishwapinnawala Which version of voice kit do you have ?
Have you reflashed the kit with the image provided at https://github.com/google/aiyprojects-raspbian/releases/tag/v20191113 ?

[vishwapinnawala]

V2 yes i tried reflashing several times and nothing seems to work

[daOrangePeeler]

I'm getting an identical error with voice kit v1. I also tried reflashing the image with no success.

[daOrangePeeler]

I fixed the error for my setup with the Raspberry Pi 3B with AIY Voice Kit v1. In the file "/home/pi/AIY-projects-python/src/aiy/assistant/auth_helpers.py", I changed the last argument in webbrowser.register() (line 75) from "-1" to "preferred=True".

Here is the documentation that explains the options for webbrowser.register(). It looks like in Python 3.7, the webbrowser.register() "preferred" argument only takes keywords now.

Here is the full, edited file. GitHub wouldn't let me upload the file directly, so the file is on Google Drive.

Or, if you just want to edit the code directly, here is the new code for line 75 in the file "/home/pi/AIY-projects-python/src/aiy/assistant/auth_helpers.py":
webbrowser.register('chromium-browser', None, webbrowser.Chrome('chromium-browser'), preferred=True)
(Make sure to leave the spaces from the original line of code in front of the new code segment as spacing matters in Python).

Please let me know if it works or not, or if you have any questions.

The above solved the problem of opening the browser and authenticating the voice kit as it takes me to the web page that says the process is complete, but then the next time I do "assistant_grpc_demo.py" again, it just starts this authentication process all over again instead of starting up like it is supposed to. (I had it working before.) I am stuck at this point for now.

[vishwapinnawala]

i've removed and got alexapi installed so i gived it up😁

I'm sorry to hear that stevesss. I just reflashed the image, created a new Google Cloud project and edited the auth_helpers.py file without success in replicating your problem. What Raspberry Pi and Voice Kit version are you using? I know it is a long process, but you might want to try reflashing your image.

[d3acon]

Editing auth_helpers.py solved it for me too. But I get a seg fault, once I did the authorisation in the browser.

[mcmanus-git]

I'm having the same issue as @d3acon

[daOrangePeeler]

I get a segmentation fault as well for every file except "assistant_grpc_demo.py"

[d3acon]

I opened a new ticket for the seg fault, as this one is for the python problem.

please check i have written a blog on all error that i have encountered
