says:
Type the following command line and press enter:
voice/assistant_grpc_demo.py (incorrect the path is incomplete)
src/examples/voice/assistant_library_demo.py (correct)

provide a temporary solution:

make a backup of auth_helpers.py

modify the 75 line to "webbrowser.register('chromium-browser', None, webbrowser.Chrome('chromium-browser'))"

restart assistant_library_demo.py , it may work~

Thank you for this feedback
I have modified the file line 75 in:
/home/pi/AIY-projects-python/src/aiy/assistant/auth_helpers.py
and then could execute
src/examples/voice/assistant_grpc_demo.py
carry out authentication
all perfect
