Create and activate python 3.5 virtual environment

python3.5 -m venv .venv

Install tensorflow

wget https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.13.1/tensorflow-1.13.1-cp35-none-linux_aarch64.whl

pip install cython
pip install --update setuptools

./build.sh

For anyone trying this as of 2023-06-20, it might be best to try the steps below.

Create a default ALSA resource file

cat <<EOF > ~/.asoundrc
pcm.!default {
	type hw
	card 0
}

ctl.!default {
	type hw           
	card 0
}
EOF

Binary Install

1. wget https://github.com/MycroftAI/mycroft-precise/releases/download/v0.3.0/precise-all_0.3.0_aarch64.tar.gz
2. tar xvf precise-all_0.3.0_aarch64.tar.gz
3. cd precise
4. Create data/activate.wav # it will try to play this file on detection

Get Keyword Model

1. wget https://github.com/MycroftAI/precise-data/raw/models/hey-mycroft.tar.gz
2. tar xvf hey-mycroft.tar.gz

Run Listener

1. ./precise-listen hey-mycroft.pb

On an Manjaro Linux aarch64 system I got some ALSA errors, no doubt remedied through config files, but it still worked.
