tf.compat.v1.math.reduce_max | TensorFlow v2.16.1 (original) (raw)

tf.compat.v1.math.reduce_max

Computes tf.math.maximum of elements across dimensions of a tensor. (deprecated arguments)

tf.compat.v1.math.reduce_max(
    input_tensor,
    axis=None,
    keepdims=None,
    name=None,
    reduction_indices=None,
    keep_dims=None
)

This is the reduction operation for the elementwise tf.math.maximum op.

Reduces input_tensor along the dimensions given in axis. Unless keepdims is true, the rank of the tensor is reduced by 1 for each of the entries in axis, which must be unique. If keepdims is true, the reduced dimensions are retained with length 1.

If axis is None, all dimensions are reduced, and a tensor with a single element is returned.

Usage example
>>> x = tf.constant([5, 1, 2, 4]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=int32, numpy=5> >>> x = tf.constant([-5, -1, -2, -4]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=int32, numpy=-1> >>> x = tf.constant([4, float('nan')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=nan> >>> x = tf.constant([float('nan'), float('nan')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=nan> >>> x = tf.constant([float('-inf'), float('inf')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=inf>

Usage example

>>> x = tf.constant([5, 1, 2, 4]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=int32, numpy=5> >>> x = tf.constant([-5, -1, -2, -4]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=int32, numpy=-1> >>> x = tf.constant([4, float('nan')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=nan> >>> x = tf.constant([float('nan'), float('nan')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=nan> >>> x = tf.constant([float('-inf'), float('inf')]) >>> tf.reduce_max(x) <tf.Tensor: shape=(), dtype=float32, numpy=inf>

See the numpy docs for np.amax and np.nanmax behavior.

Args
input_tensor	The tensor to reduce. Should have real numeric type.
axis	The dimensions to reduce. If None (the default), reduces all dimensions. Must be in the range [-rank(input_tensor), rank(input_tensor)).
keepdims	If true, retains reduced dimensions with length 1.
name	A name for the operation (optional).
reduction_indices	The old (deprecated) name for axis.
keep_dims	Deprecated alias for keepdims.

Returns
The reduced tensor.
