tf.reduce_all()

tf.reduce_all(input_tensor, reduction_indices=None, keep_dims=False, name=None)

Computes the "logical and" of elements across dimensions of a tensor.

Reduces input_tensor along the dimensions given in reduction_indices. Unless keep_dims is true, the rank of the tensor is reduced by 1 for each entry in reduction_indices. If keep_dims is true, the reduced dimensions are retained with length 1.

If reduction_indices has no entries, all dimensions are reduced, and a tensor with a single element is returned.

For example:

# 'x' is [[True,  True]
#         [False, False]]
tf.reduce_all(x) ==> False
tf.reduce_all(x, 0) ==> [False, False]
tf.reduce_all(x, 1) ==> [True, False]
Args:
  • input_tensor: The boolean tensor to reduce.
  • reduction_indices: The dimensions to reduce. If None (the default), reduces all dimensions.
  • keep_dims: If true, retains reduced dimensions with length 1.
  • name: A name for the operation (optional).
Returns:

The reduced tensor.
