I used the same code from this link, but the results are not the same as in the link.

Works fine for me:

(NB: `Precompiling project... 208 dependencies successfully precompiled in 472 seconds. 67 already precompiled.` and `Precompiling project... 106 dependencies successfully precompiled in 795 seconds. 306 already precompiled.`, that’s quite the stack to install and set up…)

Make sure you’re on the latest versions for all the relevant packages used in the tutorial.

Looks like the training step wasn’t ran? That’s pretty much what I’d expect from the random initialization.
