error with flax < 0.8

[tylerflex]

Just a heads up, with jax==0.4.26 and flax==0.7.* I was getting errors when importing sax installed recently with pip install --upgrade sax

>>> import sax
Traceback (most recent call last):

    return jax_config.define_bool_state('flax_' + name, default, help)

It was fixed when pip install --upgrade flax installed 0.8.*.

Not sure if this is something you might need to know for setting requirements but thought I'd let you know / create a paper trail in case others see this, feel free to close
