PyGrid not working after pip install

[SimonDedman]

To use this move-to-next-monitor program I needed to do

sudo apt install python3-pip
pip install ewmh-m2m
export PATH=/home/simon/.local/bin:$PATH

After which PyGrid no longer works. My shortcuts are still the same in config:

"keys": {
    "accelerator": "<Mod1><Mod4><Mod2>",
    "commands": {
      "Prior": "maximize",
      "KP_1": "bottomleft",
      "KP_2": "bottom",
      "KP_3": "bottomright",
      "KP_4": "left",
      "KP_5": "middle",
      "KP_6": "right",
      "KP_7": "topleft",
      "KP_8": "top",
      "KP_9": "topright",
      "KP_0": "cycle-monitor"

(I've only just seen that KP_0 is cycle monitor, doh!)

Any idea why this would be and what I can do to restore it?

Thanks!

For some reason it's now working again despite me not changing anything. Super weird.
