NodeRed won't work after installing this node on RPi Zero W. #15

Hi, Thanks for creating this node.

I tried to install "node-red-contrib-tensorflow" on my NodeRed (v3.0.2) instance on Raspberry Pi Zero W using Pallate Manager. It was taking a long time, so I left the installation process for some time. When I got back the NodeRed had crashed and was not reachable on URL.

I could reach Pi by SSH (only NodeRed was not working) and so tried to restart Node Red. "node-red-restart", "node-red-start" and "node-red-start --safe" all commands gave me following error.

harish@raspberrypi:~ $ node-red-start --safe

Start Node-RED

Once Node-RED has started, point a browser at http://192.168.31.229:1880 On Pi Node-RED works better with the Firefox or Chrome browser

Use node-red-stop to stop Node-RED Use node-red-start to start Node-RED again Use node-red-log to view the recent log output Use sudo systemctl enable nodered.service to autostart Node-RED at every boot Use sudo systemctl disable nodered.service to disable autostart on boot

Also, I could see files related to this node in .node-red directory. Finally decided to uninstall using NPM command. As soon as node got uninstalled NodeRed started working again. (without even a restart).

Thank you for raising the issue. I tested this node on Raspberry Pi 4 only. Because Raspberry Pi Zero W has little memory and the process takes a long time, please use Raspberry Pi 4.
