Error reading in CSR graph

[VHRanger]

This is because your node IDs should be factored when they get read into the graph.

Eg. the IDs of the nodes should start at 0 and the maximum node ID should be equal to the number of nodes.

CSRGraphs currently only supports up to 4B nodes (uint32_max) -- anyways that's about as much as you can fit on a single machine. Since you're passing in invalid node IDs here it explodes the logic.

I could fix it when I'm back next week, but in the mean time try factoring your node IDs.

Thanks for the response. I have factored the ids but get the following error -
~/anaconda3/envs/python3/lib/python3.6/site-packages/csrgraph/graph.py in init(self, data, nodenames, copy, threads)
107 raise ValueError(f"""
108 Out of bounds node: {max_idx}, nnodes: {self.nnodes}
--> 109 """)
110 # Manage threading through Numba hack
111 if type(threads) is not int:

ValueError:
Out of bounds node: 1897, nnodes: 956

Number of nodes in my edgelist are 1898, I am not sure how nnodes = 956. Attached sample edgelist for debugging.

@VHRanger any update here?

I'm tracking the changes for this in the CSRGraph repo: VHRanger/CSRGraph#3

I made some changes there which should make it work. Please test that it fixes your problem. If it does, I'll push the fix to the pip version of the CSRGraphs package (and update the dependency on nodevectors afterwards).

I'll close the issue here for now since this is a CSRGraphs issue, not really a nodevectors issue.
