Topk operation tensorflow opcode error

Projects Programming

Hi, I get a following error when trying to load tflite model into my arduino board (Arduino Nano 33 BLE). I converted my model using tf-2.4.0 and used TensorFlow Lite Micro Library for Arduino github.

The error message is :
didn't find op for builtin opcode 'TOPK_V2' version '1'. An older version of this builtin might be supported.

Is there a topk function in tflite micro for arduino? I see the opcode in the github

where BuiltinOperator_TOPK_V2 returns kTfLiteOk.
