Sunset jax_expr in numpy NIFTy
I think it is fair to say that Operator.jax_expr
never got that much traction. Furthermore, it is not the kind of model building that we want to encourage. @all WDYT about removing jax_expr
s from NIFTy operators again? It was a nice idea when I started developing NIFTy.re but it turned out to be an ineffective aproach.
