LPIPS gives negative value

[mshooter]

Hi everyone,

my pseudo code is

loss = LearnedPerceptualImagePatchSimilarity(net_type="vgg", normalize=True) 
y_hat = model(x) 
loss(x, y_hat) 

both x and y_hat have values between [0,1].
But I don't understand why my loss is negative..

Same but with input values between [-1,1].
I am using it as a training loss.
