Grove Ai V2 shows invoke failed

Hello, every time i upload a model it shows me invoke failed and doesn’t show the live screen of grove ai v2 on the device logger. I am using ov5647 pi cam module. Had mailed too but haven’t recieved any response.

Invoke failed error has been discussed here too: Grove Vision AI V2 issues with SenseCraft AI - #19 by Jon_Hylands but I cannot see any suggested solution.
