How can I run tensorflow model on OpenMV 4 Plus

I trained a object detection model with TensorFlow Object Detection API and it worked in my PC,so I want to convert the model to int8 TF tflite model , but I don’t know why it failed, so I would like to ask for help. How can I convert the model with tensorflow, very thanks for help me!

Please use Edge Impulse to help with this. The whole TensorFlow library is a mine field.

Thanks for your response.but I still prefer to train locally. So I would like to have a try, and thank you for your reply.
