Concaténez les éléments du TensorArray en value value
.
Résumé
Prend T
éléments de formes
(n0 x d0 x d1 x ...), (n1 x d0 x d1 x ...), ..., (n(T-1) x d0 x d1 x ...)
et les concatène en un Tenseur de forme :
```(n0 + n1 + ... + n(T-1) x d0 x d1 x ...)
All elements must have the same shape (excepting the first dimension).
Arguments:
* scope: A Scope object
* handle: The handle to a TensorArray.
* flow_in: A float scalar that enforces proper chaining of operations.
* dtype: The type of the elem that is returned.
Optional attributes (see Attrs
):
* element_shape_except0: The expected shape of an element, if known,
excluding the first dimension. Used to validate the shapes of
TensorArray elements. If this shape is not fully specified, concatenating
zero-size TensorArrays is an error.
Returns:
* Output
value: All of the elements in the TensorArray, concatenated along the first
axis.
* Output
lengths: A vector of the row sizes of the original T elements in the
value output. In the example above, this would be the values:
(n1, n2, ..., n(T-1))
