What is the behavior of :#x in the f-string?
There was a problem hiding this comment.
The :#x formats the id of the object as a 0x[hex] to keep the repr method consistent with the default other than adding the shapes.
>>> from numpyro import distributions as dists
>>>
>>> d = dists.Normal().expand((5, 10, 7)).to_event(2)
>>> d
<numpyro.distributions.distribution.Independent object at 0x10723f7c0 with batch shape (5,) and event shape (10, 7)>
>>> object.__repr__(d)
'<numpyro.distributions.distribution.Independent object at 0x10723f7c0>'

Looks good! Thanks @tillahoffmann.
I checked print(Normal) and print(Normal()) and test case. All behave as expected.
