Teachable Machine Image only works with webgl back end (1.2.1)

Issue Type

Broken API/Method

ml5.js Version

1.2.1

Development Environment

p5.js web editor

Browser & Operating System

Chrome

Issue Description

The Teachable Machine examples no longer work. This was introduced in 1.2.1. They work, however, if you force ml5.setBackend('webgl'). Something seems to be wrong with using webpgu and the teachable machine models? I discovered this in office hours and haven't had the time to investigate deeply.

I've manually made the fix in this example. https://editor.p5js.org/ml5/sketches/VvGXajA36
