Hello all,
I hope someone can help me. I would like to install the object recognition node-red-contrib-tfjs-coco-ssd on my RaspberryMatic. Unfortunately it does not install correctly. During the installation I get the following error.
root@homematic-raspi:/usr/local# cd /usr/local/addons/redmatic/var
root@homematic-raspi:/usr/local/addons/redmatic/var# npm i node-red-contrib-tfjs
-coco-ssd

It seems clear that Python is missing. Unfortunately, I don't know how to get Python to work on my RaspberryMatic 
It is still the last piece of the puzzle to get my monitoring system working. I hope someone can help.
Thanks at all
