Keypoint regression example

[itan1]

Running these steps in my REPL worked but only gave me the following problem

• the FastAI.decodeypred(task, Training(), y) check does not have the same coordinates as the original keypoint k

Running it in a local notebook gives me the following problems

• The first image plotted with DataAugmentation.showitems looks like this
  
• The kernel dies every time I try to run showbatch(task, (xs, ys))

Can someone try to reproduce this? I'm not sure whether these are environments problems (running with julia 1.7.2 and the mac M1 arm architecture is not fully supported yet).

Thanks for taking a look at this!

I think this should be solved by a an using ImageShow import

the FastAI.decodeypred(task, Training(), y) check does not have the same coordinates as the original keypoint k

It does not give the same keypoint since the image is cropped to 128x128. Important part is that the decoded keypoint is within those bounds 👍

The kernel dies every time I try to run showbatch(task, (xs, ys))

Cannot reproduce this, may be a problem with Makie.jl on ARM :/ . Have you tried updating packages in your environment?

Changes look good to me, merging!

Great thank you too! This package is helping me a lot 🙌

Ok thanks for the clarification, I think I got it. The decode function only reverses the coordinate normalization, not the cropping. Is that correct?

[lorenzoh]

Exactly, since the cropping is a destructive operation
