PopulationCount
Mantenha tudo organizado com as coleções
Salve e categorize o conteúdo com base nas suas preferências.
Calcula a contagem da população elemento a elemento (também conhecida como popcount, bitsum, bitcount).
Para cada entrada em `x`, calcula o número de bits `1` (on) na representação binária dessa entrada.
NOTA : É mais eficiente primeiro tf.bitcast seus tensores em `int32` ou `int64` e executar a contagem de bits no resultado, do que alimentar entradas de 8 ou 16 bits e então agregar as contagens resultantes.
