The part about einsum is really nice!  I propose we add a nice comment
in the code (of your PR) to explain what's happening on that einsum
line, because most  people won't have a clue :)

You can often write einsum as some operation + a reduction over one or
more axes.  Can this operation be expressed in both ways?  If so,
which do you find to be more readable and understandable?

Thanks!
