Advice on checking convergence with SVGD

Because SVGD doesn’t optimize the ELBO, it doesn’t record the ELBO objective in hist at each iteration. I’d like to get a sense of how many iterations I need, but I don’t want to create a Tracker that saves svgd.approx.histogram.eval at every iteration, because that’s not really scalable with my high-dimensional model and rather large number of particles. Any recommendations?
