Returning very large arrays
I'm seeing very large arrays being returned, with all the data after the initial "correct" data looking like old memory:
import numpy as np
import LAPJV
n = 8
cost = np.random.uniform(low=0, high=100000, size=(n, n))
%time min_cost,row_assigns,col_assigns,row_dual_vars,col_dual_vars = LAPJV.lap(cost)
print row_assigns.shape
print row_assigns[:(2*n)]
Output:
CPU times: user 12 µs, sys: 7 µs, total: 19 µs
Wall time: 16 µs
(988661682962169864,)

For what it's worth, there's another wrapper for lapjv that doesn't have this problem https://github.com/gatagat/lapjv
