@kevinsouthxu No it does not. The range is `[1,num_nodes-1)` -> `[1,num_nodes-2]` but inside you work with `outDegree[i-1]` which means you're actually using the range `[0,num_nodes-3]` Then at the end, he...

@kevinsouthxu it was actually running fine on mine too, but it's by luck since it's undefined behaviour. You should run tools such as `valgrind` or `compute-sanitizer` (the latter is available...

Any update regarding this issue? New versions of python can't support the library anymore as tensorflow is no longer available for those versions
