I am using DGL to implement the pinsage example. However, when run the random sampler, it reports no successors from vertex. Maybe my data is too sparse… There are only four parameters I could change, such as max_nodes_per_seed, max_visit_counts, max_frequent_visited_nodes, and restart_prob in the “bipartite_single_sided_random_walk_with_restart” function.
I have tried relaxed max_nodes_per_seed to a bigger number, and lowered restart probability, but it still failed.Could you show me how to modify these parameters？Thank you！
Best Regards~
