`np.ndarray` vs `list` discrepancy

[Sentient07]

Hi,

I'm facing a discrepancy between np.ndarray and python list. here's a reproducible code.

(Pdb) munkres_inst.compute(cost_matrix)
*** ValueError: non-broadcastable output operand with shape (1,) doesn't match the broadcast shape (2,)
(Pdb) cost_matrix
array([[1.20000000e+20],
       [1.20000000e+20],
       [4.51233041e-01]])
(Pdb) munkres_inst.compute(cost_matrix.tolist())
[(2, 0)]
(Pdb) cost_matrix.tolist()
[[1.2e+20], [1.2e+20], [0.45123304109052526]]

Could you please let me know if this is a mistake on my end or a bug with the library? Thanks!

Regards,

Hello! I don't believe this library is intended to work on NumPy arrays, so converting with .tolist() first is the right thing to do.
