@dceejay I just installed this on a Pi Zero W and when I first deployed it crashes NR with

```auto
10 Mar 17:37:12 - [info] Stopped modified flows
10 Mar 17:37:12 - [info] Starting modified flows
Illegal instruction

```

after that I can only start Node-RED with the --safe option or it crashes during startup.

I was so hoping it would run on the zero. ☹

Want a issue or PR updating the documentation to let people know about this?

Here is the install log:

```auto

Sure. I don't think they build tensor flow binaries for arm6 so its never going to work.

Is this the tensor flow?

Looks like they do have a version for pi 1/zero. Might there be hope?

I would if I knew what I was needed to do. Any hints?

FYI I got your node running on a Pi3 to recognize people and want to use it in my "Wash your hands!' coronavirus project. I was hoping I could stick it on a Pi Zero to reduce the cost of building this for my pregnant daughter.

If I can't get it running, I'll just use a Pi3 but it would be nice to use the Pi Zero.

Well I'm using the tensorflowjs libraries. No idea how to replace the guts of that with those other ones.
