getting cartonize wasm to work on codepen

[Angelina]

I am trying to get a tfjs-tflite demo from here

to get it to work on codepen here

The goal is to cartoonise the image on the top row and generate its corresponding cartoon via GAN on the second row.You can see here an official example of what the result should look like: https://storage.googleapis.com/tfweb/demos/cartoonizer/index.html

For some reason, it does not seem to produce a result :(

Any clue as to why this is would be greatly appreciated (I am a JS newbie).
