useless parameter iter_

[BloomingStone]

In the module soft_cldice at /cldice_loss/pytorch , there is a parameter iter_ that used to initialize self.iter, but then nerver used.

class soft_cldice(nn.Module):
    def __init__(self, iter_=3, smooth = 1., exclude_background=False):
        super(soft_cldice,  @self).__init__()
        self.iter = iter_
        self.smooth = smooth
        self.soft_skeletonize = SoftSkeletonize(num_iter=10)
        self.exclude_background = exclude_background

    def forward(self, y_true, y_pred):
        if self.exclude_background:
            y_true = y_true[:, 1:, :, :]
            y_pred = y_pred[:, 1:, :, :]
        skel_pred = self.soft_skeletonize(y_pred)
        skel_true = self.soft_skeletonize(y_true)
        tprec = (torch.sum(torch.multiply(skel_pred, y_true))+self.smooth)/(torch.sum(skel_pred)+self.smooth)    
        tsens = (torch.sum(torch.multiply(skel_true, y_pred))+self.smooth)/(torch.sum(skel_true)+self.smooth)    
        cl_dice = 1.- 2.0*(tprec*tsens)/(tprec+tsens)
        return cl_dice
