About loading tflite model converted with tensorflow ops enabled in imx8mp

Hello
thank you for your reply

I converted from a tensorflow model (* .pb) to a tflite model (* .tflite). The conversion can be completed without error.
The model is a customized model that uses select ops (conv3d etc).
I’m only using the tflite runtime at runtime

Run-time code

import tflite_runtime.interpreter as tflite
interpreter = tf.lite.Interpreter(model_path=args.model_file)           <---error

No error occurred when checking with label_image.py
