From this (and many other) tutorial it is not clear if tensors in tensorflow are true mathematical tensors (that is, having covariant and contravariant indices) or they are multidimensional arrays. The name Tensorflow and terminology suggests that Tensorflow manipulates mathematical tensors, for example:

  Scalars -> Vectors -> Matrices -> Tensors (really tensors?)

but what you see are multidimensional arrays. It is of course not a big problem but probably could be clarified somewhere at least in small font to avoid ambiguity. Or Tensorflow objects are true tensors indeed?
