Hello,

I’m having a problem using roboflowoak. It is similar, but a bit different to the below post, so I’ve started a new thread
Basically, the DepthAI window appears momentarily, then disappears and I get the following error

I’d appreciate any help- thank you

Try using the barrel plug for additional power to Oak. This cures some problems.

Mine has said “divide by zero error” also but this hasn’t stopped operation.

thanks Russ- But I am already using the barrel plug
