Demo.ipynb not Runnable #3

I've tried running the demo notebook but it doesn't run majorly because it's missing arcface models.

I downloaded the model from

wget -P ./arcface_model https://github.com/neuralchen/SimSwap/releases/download/1.0/arcface_checkpoint.tar

but this just gives error:

{
    "name": "TypeError",
    "message": "'ResNet' object is not subscriptable",
    "stack": "---------------------------------------------------------------------------

     65 netArc_checkpoint = torch.load(netArc_checkpoint)
---> 66 self.netArc = netArc_checkpoint['model'].module
     67 self.netArc = self.netArc.to(device)
     68 self.netArc.eval()

TypeError: 'ResNet' object is not subscriptable"
}

so, i thought the problem would be with how we're using it in fs_model.py so i changed the loading code to this:

 # Load the ArcFace model
        netArc_checkpoint = opt.Arc_path
        self.netArc = torch.load(netArc_checkpoint)
        self.netArc = self.netArc.to(device)
        self.netArc.eval()

then i downloaded the checkpoint models from here. https://drive.google.com/drive/folders/1jV6_0FIMPC53FZ2HzZNJZGMe55bbu17R

unzipped them, now they run but arcface_models.py is missing.

i downloaded from the baseline repo you provided but there is tensor shape error:

RuntimeError: view size is not compatible with input tensor's size and stride (at least one dimension spans across two contiguous subspaces). Use .reshape(...) instead.

so i updated the resnet model as well.

this is the new file.

        one_hot.scatter_(1, label.view(-1, 1).long(), 1)
        output = (one_hot * phi) + ((1.0 - one_hot) * cosine)
        output *= self.s
        return output

finally, inside the drawing results in demo.ipynb, i changed the lines to these:

# Load the ArcFace model
netArc_checkpoint = opt.Arc_path
netArc_checkpoint = torch.load(netArc_checkpoint)
netArc = netArc_checkpoint.to(device)
netArc.eval()

Now it runs.

Thanks for your fix very mush🙂🙂!! This might have been caused by the version of Arc_face.
