Porcupine Issue: syntax error raised when running porcupine_demo_mic

Make sure you have read the documentation, and have put forth a reasonable effort to find an existing answer.

Expected behaviour

Unknown, code does not run

Actual behaviour

With environment variable ACCESS_KEY set to access key from picovoice account and with network access available.

$ porcupine_demo_mic --access_key ${ACCESS_KEY} --keywords porcupine
Traceback (most recent call last):
  File "/usr/local/bin/porcupine_demo_mic", line 6, in <module>
    from pvporcupinedemo.porcupine_demo_mic import main
  File "<fstring>", line 1
    (self._access_key=)
                     ^
SyntaxError: invalid syntax

With access code encoded in command

$ porcupine_demo_mic --access_key O6m<redacted middle of access code>4fg== --keywords porcupine
Traceback (most recent call last):
  File "/usr/local/bin/porcupine_demo_mic", line 6, in <module>
    from pvporcupinedemo.porcupine_demo_mic import main
  File "<fstring>", line 1
    (self._access_key=)
                     ^
SyntaxError: invalid syntax

Steps to reproduce the behaviour

Running on hyproit on RPi 3B+ which comes with python 3.7.3 Installed pvporcupine as per destructions at: https://picovoice.ai/docs/quick-start/porcupine-python/

Tried example python code but could not resolve issues I was finding it would not resolve the env to pick up the access key.

$ python
Python 3.7.3 (default, Dec 20 2019, 18:57:59)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pvporcupine
>>> porcupine = pvporcupine.create(
...   access_key='${ACCESS_KEY}',
...   keywords=['picovoice', 'bumblebee']
... )
[ERROR] failed to parse AccessKey '${ACCESS_KEY}'

I tried embedding the key in the code and the code worked fine with access key embedded in the code, except the python code example was obviously stunted and not a full example.

Opted into using the demo at https://picovoice.ai/docs/quick-start/porcupine-python/#demo and so then arrived at the syntax error reported at the top.

Uninstalled everything then reinstalled but then got:

$ porcupine_demo_mic --access_key ${ACCESS_KEY} --keywords porcupine
-bash: /usr/local/bin/porcupine_demo_mic: No such file or directory

$ porcupine_demo_mic --access_key O6mlLw<redacted middle of key>ujA//WcHJ8w4fg== --keywords porcupine
-bash: /usr/local/bin/porcupine_demo_mic: No such file or directory

$ porcupine_demo_mic --help
-bash: /usr/local/bin/porcupine_demo_mic: No such file or directory

As I was setting a new RPi with hyproit, I reburned the SD card from scratch and so the first thing I tried was pip3 install pvporcupinedemo and then

$ /home/pirate/.local/bin/porcupine_demo_mic --access_key O6mlLwkDR<redacted middle of key>BrujA//WcHJ8w4fg== --keywords porcupine
Traceback (most recent call last):
  File "/home/pirate/.local/bin/porcupine_demo_mic", line 6, in <module>
    from pvporcupinedemo.porcupine_demo_mic import main
  File "<fstring>", line 1
    (self._access_key=)
                     ^
SyntaxError: invalid syntax

I have tried no quotes, single and double quotes around the key - to same end result. Network has been up the entire time (and would need to be since I am sshing into the RPi and pulling down files using pip3).

So, I burned onto a SD:

Raspberry Pi OS Lite
Release date: October 30th 2021
Kernel version: 5.10

Setup wifi and ssh so I could get files from my PC (test.wav for example).

Ran:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get python3-pip
sudo pip3 install pvporcupinedemo

Python version that comes with:

pi@raspberrypi:~ $ python --version
Python 3.9.2

As for previous report, the demo versus the wav file worked. So this time did:

porcupine_demo_mic --access_key O6mlLwkDR8A<redact middle of key>jA//WcHJ8w4fg== --keywords porcupine --audio_device_index 1

So is this the difference between Python 3.7.3 that came with hypriot and the 3.9.2 that comes with RPi OS Lite? I’ll look into it.

Hmmm. Can’t help at the moment. https://github.com/Picovoice/porcupine/issues/653 so I’ve a few weeks left before I can try again. But isn’t it odd then that it looked like I had sorted my problem by installing 3.9.2 on hypriot, since it wasn’t apparently a problem on the Raspian OS, but then which Raspian version may be the question. Double hmmn.
