we build our model with input shape [None, None, 3], and set shape to [None, None, 3] using concrete_func when converting. it can be successfully converted. we convert our model from saved_model. hope this helps!
Hi, are we allowed to do padding outside the model?
Our model needs input shape to be divisible by a factor. For model_none.tflite with arbitrary input shape (required in submission), we cannot know the input shape and cannot decide the pad size.
