Error while Installing NPM node-red-contrib-tfjs-coco-ssd

[Christchoper]

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

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

Thanks at all

This is a module with binary dependencies. Needs to be supplied pre-compiled by @hobbyquaker Nothing you can do ATM.

@Sineos Thanks for the quick reply.

@hobbyquaker Is there a way to make this node available? That would be great. Kindest regards

[hobbyquaker]

Ist in 7.2.0 enthalten

Hallo Hobbyquaker, Besten Dank für das integrieren des tf coco ssd-Node. Ich konnte es erfolgreich installieren. Leider bekomme ich aber den Node nicht in den Status "model ready". Ich habe es mit dem Basic Beispiel von dieser Seite getestet:

https://flows.nodered.org/node/node-red-contrib-tfjs-coco-ssd

Kannst Du vielleicht weiterhelfen?
