Can't run random walk algorithm

Hi all,

I was trying to run the “random_walk” algorithm with no success.
I am using a graph schema with many node types (movies, actors, production) and many edges (acted, produced).

running the random walk with step=1, path_size=8, all the edges types and sample_num=10, 1000, 100 (I tried all of them) ended up to be empty paths.

reducing the path_size to 3, return results.

Is it a known problem?

In addition, when I ask for path_size=8 do I get 8 in deep or it’s actually one level deep only 8 times?


The path_size is to decide the number levels deep the random walk will happen. So in your case if the starting node doesn’t have path to walk 8 levels deep it will be null.
