Faulty Edge TPU? Very slow inference speeds #765

Closed Morphy99 closed 1 year ago

Morphy99 commented 1 year ago

I've just purchased some dual edge TPU's off eBay and it seems one of them has a very slow inference speed when running Frigate. I'm getting 165ms where as with other TPU's on the same hardware, I'm getting more like 10-11ms. Has anyone come across a "bad" board before?

@Morphy99 could you please check your host machine detecting two TPUs with below command, as most of the hardwares support only one TPU. Thanks!!

Hi thanks but it only detects one TPU, this is not the issue though. I have two other dual edge boards where the inference speed is normal.

Okay, I haven't seen this type of issue so far. Please return the device to original reseller. Thanks!!
