Hi @Richienb!

Thank you for your pull request and welcome to our community.

Action Required

In order to merge any pull request (code, docs, etc.), we require contributors to sign our Contributor License Agreement, and we don't seem to have one on file for you.

Process

In order for us to review and merge your suggested changes, please sign at https://code.facebook.com/cla. If you are contributing on behalf of someone else (eg your employer), the individual CLA may not be sufficient and your employer may need to sign the corporate CLA.

I think sigma (σ) should instead be called var for "variance". For example, mean is not called mu (μ).

[NicolasHug]

That's fair @Richienb , I can't claim mean and sigma are the best name combination, but unfortunately for consistency this is probably what we'll need to use, as these are the names that are already used by GaussianBlur.

[Richienb]

Ok, let's save this for a future breaking change.

[NicolasHug]

Thanks for the PR @Richienb , as you've seen I've made a few changes to the original implementation, but this LGTM now. In particular the transform enforces tensors with float dtype (PIL isn't supported). We might add support for that later but that would require a dtype conversion to avoid over/underflows, so it's best to treat it separately. Thank you again for the PR!
