Hi, I'm using OT package for GW, and I have a question regarding choosing the optimal value for entropic regularization. What is the good objective to choose epsilon and what are the ranges to try. gw, log = ot.gromov.entropic_gromov_wasserstein( C1, C2, p, q, 'square_loss', epsilon=5e-4, log=True, verbose=True) Best, Azim
