DeepLabV3 and DeepLabV3+ cannot use encoder “Xception”

[MrLangZe]

hi，when i run model = Model("deeplabv3", "xception", in_channels=3, out_classes=OUT_CLASSES) , the error is "ValueError: Xception encoder does not support dilated mode due to pooling operation for downsampling!". So how can i solve it?

Hey @MrLangZe, indeed, Deeplab models require the last stages of the encoder to be with the same stride, which is not supported for all encoders. At the moment there is no way to fix it out of the box for Xception, it would be easier to use another encoder.

Thanks for your reply!
