Getting Started

$pip install latentshift

import latentshift
# Load classifier and autoencoder
model = latentshift.classifiers.FaceAttribute(download=True)
ae = latentshift.autoencoders.VQGAN(weights="faceshq", download=True)

# Load image
input = torch.randn(1, 3, 1024, 1024)

# Defining Latent Shift module
attr = captum.attr.LatentShift(model, ae)

# Computes counterfactual for class 3.
output = attr.attribute(input, target=3)
