Issues using PV on Pi 5

[tmart42]

I am attempting to utilize the package in order to create a DaVinci voice assistant using a Raspberry Pi 5. I am getting the following error when trying to start DaVinci. I posted on their issues section as well, but I see that the issue is with pvcobra specifically, so I came here.

The error:

Cobra doesn't support RPI5 currently. We are planning to add RPI5 support early next year. I keep this issue open till then.

As a temporary solution... I have found that adding the following lines in the CPU sections of the below python package files allows PicoVoice to function as normal. I only tested this on python3.11 and Raspi 64-bit Bookworm. Use at your own risk of course...

pvcobra

Adding:
elif '0xd0b' == cpu_part:
return 'cortex-a72' + arch_info
In:
/venv/lib/python3.11/site-packages/pvcobra/_util.py

pvleopard

Adding:
elif '0xd0b' == cpu_part:
return 'cortex-a72' + arch_info
In:
/venv/lib/python3.11/site-packages/pvleopard/_util.py

pvporcupine

Adding:
elif '0xd0b' == cpu_part:
return 'cortex-a72' + arch_info
In:
/venv/lib/python3.11/site-packages/pvporcupine/_util.py

pvrecorder

Adding:
"0xd0b") kernel="raspberry-pi" arch="cortex-a72"$arch_info ;;
In:
/venv/lib/python3.11/site-packages/pvrecorder/resources/scripts/platform.sh

As mentioned in Picovoice/picovoice#721 Cobra now officially supports Raspberry Pi 5! Be sure to update to the latest package versions.
