Hi!

I've was trying to interpolating between 4 sequences with MusicVAE inside a dedicated workers and got an error.

Steps to reproduce:

  1. Create a Worker:
  2. Create a MusicVAE instance¹
  3. Call .interpolate() with an array of 4 note sequences.

¹ _tested with two checkpoints: one, two_

I've attached an example project with a MCVE: Magenta Issue 578 - Bug MCVE.zip

Note the relevant lines inside main.js and worker.js are identical.

My console output on MS EDGE:

It is related to tfjs.

Works with tfjs 2.8.6. Doesn't with tfjs 3.0.0
