tensoreflusso:: ops:: DiagPart
#include <array_ops.h> Restituisce la parte diagonale del tensore.
Riepilogo
Questa operazione restituisce un tensore con la parte diagonal input . La parte diagonal si calcola come segue:
Supponiamo che input abbia dimensioni [D1,..., Dk, D1,..., Dk] , quindi l'output è un tensore di rango k con dimensioni [D1,..., Dk] dove:
diagonal[i1,..., ik] = input[i1, ..., ik, i1,..., ik] .
Per esempio:
# 'input' is [[1, 0, 0, 0]
[0, 2, 0, 0]
[0, 0, 3, 0]
[0, 0, 0, 4]]tf.diag_part(input) ==> [1, 2, 3, 4]
Argomenti:
- scope: un oggetto Scope
- input: tensore di rango k dove k è pari e non zero.
Resi:
-
Output : la diagonale estratta.
