Proxmox >> VM (Ubuntu 20.04) >> Frigate + 2x Google Coral TPU
This assumes that you already have Proxmox (6.3+) installed and a VM running Ubuntu 20.04+ with Docker installed and a Frigate container created that you wish to pass-thru some Google Coral(s) for TensorFlow processing.
Required Hardware
You will need a Coral device. These can be purchased from okdo.com (there are other distributors)
Note: I avoided the USB device due to the high price and the low availably so instead opted to try two different PCIe devices. I can confirm both devices below work but if I had to choose I would go the mini-pcie route as it's a smaller form factor with equal performance of the m.2
