ValueError: Input contains NaN

Hello!

Thank you for providing this wonderful tool for study. I changed the second option into all for LINE (line 48 of GraphEmbedding/examples/line_wiki.py), and encountered the following error:

....

Could anyone take a look and see if that can be fixed? Thank you very much!
