Raspbery Pi 64 / Python 3.9 google.protobuf.message.DecodeError with pypi precise-runner binary #234
Description
Describe the bug
I'm porting my working code from Jetson Nano (Debian 18.02, Python 3.6) to Raspberry Pi4 (Debian 20.04, Aarch64, Python 3.9), but I'm getting a google.protobuf.message.DecodeError that prevents the engine from starting.
To get set up quickly I used the binary suggested from the readme.md
Should I try building from source, or is there something easier I'm missing?
To Reproduce
Install process
$ sudo apt install portaudio19-dev python3-pyaudio
$ wget https://github.com/MycroftAI/mycroft-precise/releases/download/v0.3.0/precise-engine_0.3.0_aarch64.tar.gz
$ tar xvf precise-engine_0.3.0_aarch64.tar.gz
$ sudo pip3 install precise-runner
$ wget https://github.com/MycroftAI/precise-data/blob/models/hey-mycroft.pb -P /home/robud/robud/ai/wakeword_detection/models/
$ wget https://github.com/MycroftAI/precise-data/blob/models/hey-mycroft.pb.params -P /home/robud/robud/ai/wakeword_detection/models/
When I run the code below, I get the subsequent error.
engine = PreciseEngine(PRECISE_EXE_PATH, PRECISE_MODEL_PATH)
detector = TriggerDetector(CHUNK, SENSITIVITY, TRIGGER_LEVEL)
engine.start()`
Warning: Failed to load parameters from /home/robud/robud/ai/wakeword_detection/models/hey-mycroft.pb.params
