Look at the tail end of learn.predict()’s code, specifically at the decode_batch() function. It’ll wind up returning your original X (the image) and the now fully decoded y

For a code example, see the “fastai straight” section here:

Speeding Up fastai2 Inference - And A Few Things Learned

First thing you’ll notice is that there will be a decent gain in speed here, the main reason I believe is because fastai is attempting to do a lot on the back end and make other various functions/utilities easy to use and try to do it as efficiently as possible which may show the lack of speed. (also if I am wrong here Jeremy or Sylvain please don’t hesitate to call me out ) With that out of the way, let’s g…
