Hi,
we have not trained the model on the ImageNet. Our model is trained on the COCO.
Maybe you can get the Xception pretrained on the ImageNet on here.

@Gaoyiminggithub It seems that link is not trained on COCO.

I am wondering whether could you share the checkpoints of the Aligned Xception (instead of Xception) trained on COCO.

@PkuRainBow
Hi, the link
https://github.com/tensorflow/models/blob/master/research/deeplab/g3doc/model_zoo.md
I provided above is the checkpoints of the Aligned Xception :) (you can see and find the imagenet and coco pretrained in it)
Maybe you confuse the link.

@Gaoyiminggithub Thanks for your quick reply, could you provide me the pytorch version or we can load the weights of the tensorflow models (in the Figure as below) directly?

@PkuRainBow
I could not provide the pytorch version right now, because I delete it after I have trained the model on coco, but maybe I could convert that in next week.
You could convert the tensorflow models to the pytorch version by extracting the weight from the tensorflow models and then fill the pytorch model.weight with it.

@Gaoyiminggithub Thanks for your help. I am wondering if you could share with me the mentioned COCO trained model.

you can download the coco pretrained model in here.
The normalization way should follow here.

@Gaoyiminggithub Thanks~

@Gaoyiminggithub Why do you comment the BN operation during the "Exit flow" as below?

        # Exit flow
        x = self.block20(x)
        x = self.conv3(x)
        # x = self.bn3(x)
        x = self.relu(x)

        x = self.conv4(x)
        # x = self.bn4(x)
        x = self.relu(x)

        x = self.conv5(x)
        # x = self.bn5(x)
        x = self.relu(x)

@PkuRainBow because I put the BN operation in self.conv3/4/5.

@Gaoyiminggithub Got it~ Besides, it would be great if you could share with me the converted Pytorch model based on the official ImageNet based tensorflow models.

Besides, I want to check with you that the data normalization is simply to convert all the values to be in the range [-1, 1]?

Thanks a lot!
