The assert error when running classification inference

The assert error when running classification inference

Hello, I am interested in the Metavision SDK and try to run the demo of classification inference from https://docs.prophesee.ai/stable/metavision_sdk/modules/ml/samples/classification_inference.html?highlight=classification.
I have installed SDK(python3.7) and anaconda environment on ubuntu 18.04, but encountered an error as shown in figure below using EVT3 GEN4.0 Event camera. The resoluition of it is 1280*720, I have tried both pre-trained models such as mobilenetv2_chifoumi and convRNN_chifoumi, and the error is same.
I think that the 720(event resolution) could not downsampled to 120(model resolution), but the resolution of camera could not be changed, so what should I adjust to run it? Or the model is trained using another camera with different resolution?
Hope for your reply.
