AttributeError: module 'jax.ops' has no attribute 'index_add'

[Adam Klein]

Description

I am trying to do something basic in my code:

import numpy as np              # regular ol' numpy
from trax import layers as tl   # core building block
from trax import shapes         # data signatures: dimensionality and type
from trax import fastmath       # uses jax, offers numpy on steroids

Upon import it errors out doing the basics here. What am I doing wrong? Should I be pinning a different version of the code?
