Unity Engine

Hi,
Is there a plan to support 3D MaxPool operator in Sentis?
If not, is there a way to add operator support myself?

Hi Joseph,
MaxPool3D is supported by the Functional API.
On how to use FunctionalGraph, here is an example.
cheers,

Thank you for the reply :slight_smile:
Would you also be able to guide me how to replace MaxPool inside the model with functional?
I see how to add functional before and after the model in given example but still not sure how to replace the existing operator inside the model.

Hi Joseph,
Where is your model coming from? How do you want to modify it? Can you modify it before exporting to ONNX ?

Model is developed in-house and I’m not the one prepared it so not sure if it is an easy thing to replace 3D MaxPool with something else. I’ll ask.
I am not allowed to share the model itself with 3rd party.

The model is using 3D MaxPool operation 3 times and Unity gives
NotImplementedException: The method or operation is not implemented error.

Hi Joseph,
Is this screen capture from Unity? The MaxPool seems to be imported.
Is there is a way to reproduce the error with a very small model that you could share?
Regards,

Yes it is imported but seems like Sentis only supports 1d and 2d MaxPool in model right now.
I’m more the Unity engineer than AI so I’m not sure how to prepare the model itself.
