Error running efficient det lite d0 model on GPU

[Arix12]

Hi,
I have trained an object detection model on my custom data using efficient det lite d0 architecture.
I have created a tflite model from a checkpoint using the export example.
The model trains fine according to tensorboard and I can run inferences just fine on my PC.
I want to run this model on an NPU so I quantized it to uint8 but when i try to run inference on the platform i get the following error:
RuntimeError: Attempting to use a delegate that only supports static-sized tensors with a graph that has dynamic-sized tensors.
From what i checked so far this error means there is a tensor with dynamic input somewhere in the graph.
I tried examining the model using netron but I couldn't find any dynamic operations.
Do you have any clue what this dynamic part might be?
Thanks.

I wanted to get an npu for testing, but failed. I'll try it out if I get it in the future.
