Using this package does bad things to my NumPy

[Hoeze]

import numpy as np

print(np.log(np.nextafter(0, np.inf, dtype=np.float64)))

from MulticoreTSNE import MulticoreTSNE as TSNE
tsne = TSNE(n_jobs=6)

print(np.log(np.nextafter(0, np.inf, dtype=np.float64)))

Result:

# print(np.log(np.nextafter(0, np.inf, dtype=np.float64)))
-744.4400719213812
# from MulticoreTSNE import MulticoreTSNE as TSNE
# tsne = TSNE(n_jobs=6)
# print(np.log(np.nextafter(0, np.inf, dtype=np.float64)))
__main__:1: RuntimeWarning: divide by zero encountered in log
-inf

After calling tsne = TSNE(n_jobs=6) my numpy is not working any more as intended.

How can I fix this?
