I’m looking to define an inverse gamma distribution using torch.distributions, similar to putting:
gamma_dist = torch.distributions.Gamma(alpha, beta)

I see that there does exist a transforms class from which one can create TransformedDistributions (refer to https://pytorch.org/docs/stable/_modules/torch/distributions/transforms.html#PowerTransform 30), however there is no 1/distribution class. How should one go about creating the Inverse gamma?
