Tsne visualisation / extracting feature vectors

Hi there,

I want to visualise my model on image classification (Lesson 2-3 level) using t-sne.
Is there a way to do this on fastai models? Can anyone share an example please?
Alternatively, how do I extract feature vectors from the second last layer? I should be able to figure it from there.

I can’t find an easy to follow example (I’m new to this…).

Thanks so much!
