Returns the index with the largest value across dimensions of a tensor.
tf.compat.v1.arg_max( input, dimension, output_type=tf.dtypes.int64, name=None )
Note that in case of ties the identity of the return value is not guaranteed.
import tensorflow as tf a = [1, 10, 26.9, 2.8, 166.32, 62.3] b = tf.math.argmax(input = a) c = tf.keras.backend.eval(b) # c = 4 # here a[4] = 166.32 which is the largest element of a across axis 0
Args | |
---|---|
input | A Tensor . Must be one of the following types: float32 , float64 , int32 , uint8 , int16 , int8 , complex64 , int64 , qint8 , quint8 , qint32 , bfloat16 , uint16 , complex128 , half , uint32 , uint64 , bool . |
dimension | A Tensor . Must be one of the following types: int32 , int64 . int32 or int64, must be in the range [-rank(input), rank(input)) . Describes which dimension of the input Tensor to reduce across. For vectors, use dimension = 0. |
output_type | An optional tf.DType from: tf.int32, tf.int64 . Defaults to tf.int64 . |
name | A name for the operation (optional). |
Returns | |
