This would be really nice to have. But I remember some folk requested such a feature (issue) but it was closed anyway. And it would be great to reconsider.

@innat Here I am requesting it again issue. Would love to work on this if it's available for contributions. Also proposed this as my GSoC idea proposal. :)

Thanks for the proposal. I think model visualization tools belong in this repo. Lets start a subdirectory visualization. GradCam can be a first component.
