Adjacency graph taking too long to generate

[nicksukie]

On a new dataset of about 1.3 million interactions, it takes almost 1 hour to create the adjacency graph. Is this correct? Is there a way to make graph creation faster?

Thank you.

Update:

I have found that it's the following step that takes an excessive amount of time:

adj_mat[:self.n_users, self.n_users:] = R

Is there any explanation for this?
