Captum implementation seems to have a bug when using image batches, but not when using single images
wrap this and go though images one by one?
alternative option:
there is a pytorch implementation that seems easy enough to wrap and use https://github.com/moboehle/Pytorch-LRP

[AxelJanRousseau]

Captum implementation and implementation from https://github.com/moboehle/Pytorch-LRP give very different results
