Describe the bug
When calling cugraph.k_core() on a directed cugraph.Graph object, the method will raise a RuntimeError: CUGRAPH_UNKNOWN_ERROR

Steps/Code to reproduce bug

>>> G = karate.get_graph(create_using=cugraph.Graph(directed=True))
>>> G.is_directed()
True
>>> a = cugraph.k_core(G)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/nfs/ralphl/miniconda3/envs/rapids/lib/python3.9/site-packages/cugraph-22.2.0a0+417.g2cd41103.dirty-py3.9-linux-x86_64.egg/cugraph/cores/k_core.py", line 101, in k_core
    core_number = _call_plc_core_number(G)
  File "/home/nfs/ralphl/miniconda3/envs/rapids/lib/python3.9/site-packages/cugraph-22.2.0a0+417.g2cd41103.dirty-py3.9-linux-x86_64.egg/cugraph/cores/k_core.py", line 27, in _call_plc_core_number
    pylibcugraph_core_number(
  File "core_number.pyx", line 124, in pylibcugraph.core_number.core_number
  File "utils.pyx", line 51, in pylibcugraph.utils.assert_success
RuntimeError: non-success value returned from cugraph_core_number: CUGRAPH_UNKNOWN_ERROR

Expected behavior
k_core() should specify that the error is caused by a directed graph, so that its behavior is similar to the other algorithms within the library.

Environment overview (please complete the following information)

  • Environment location: Bare-metal
  • Method of cuGraph install: conda
