Real-valued features not supported?

[gioschibo]

HI, thanks for the amazing library.
I do not quite understand how the data should be fed. If i create a feature vector composed by real values, i receive an error because the embedding function can handle only Long tensors, i.e., integers.
I would suggest that you add some lines to understand how data should be prepared, as the documentation lack of this content.

Thanks and best regards
