sklearn.manifold.TSNE, ValueError: Buffer dtype mismatch, expected 'float_t' but got 'float' #4124
Description
Thank you so much for adding sklearn.manifold.TSNE, I'm very excited that it's now part of sklearn! However, when I try using it, I get the following error message (both with 0.15.2 and 0.16):
Traceback (most recent call last):

vectors_tsne = do_tsne_on_vectors( vectors_in_file )

ValueError: Buffer dtype mismatch, expected 'float_t' but got 'float'To fix this, I did:
vectors = np.asfarray( vectors, dtype='float' )
which seems to work for me.
My input is a list of vectors I get from gensim.models.word2vec.
Kind regards and thanks for the great library!
