PopulationCount

Oblicza liczbę ludności według elementów (inaczej popcount, bitsum, bitcount).
Dla każdego wpisu w „x” oblicza liczbę bitów „1” (włączonych) w binarnej reprezentacji tego wpisu.
UWAGA : Bardziej efektywne jest najpierw rzutowanie tensorów tf.bitcast na `int32` lub `int64` i obliczanie bitów na wyniku, niż wprowadzanie 8- lub 16-bitowych danych wejściowych, a następnie agregowanie uzyskanych zliczeń.
