can you run this "cat /proc/cpuinfo" from terminal and paste the result here?

it seems like the new ubuntu changed the output and our logic for picking the CPU type doesn't work on this specific version of ubuntu. this is something we can look at for subsequent release.

for now, you have two options (1) clone repo directly (2) use an older version of ubuntu or use a raspbian

[StuartIanNaylor]

I will use Raspbian for now, the 64bit Ubuntu is likely to be of much interest as with the Pi4 it actually has some substantial performance gains. So clone compile and it should work? Or clone compile and hack a little and it should work? There is also a RK3308 RockpiS board that is of much interest to me but images seem to be Aarch64 but there is a Debian version 64bit version that I might try as an alternative to Ubuntu.

clone and follow the instructions here: https://github.com/Picovoice/porcupine#repository

We clarified that the PIP works on Raspberry Pi running Raspbian in v1.8. For other OSes on RPI the repo method probably will be the robust way to go.
