- paddle. all ( x, axis=None, keepdim=False, name=None )
logical andof tensor elements over the given dimension.
x (Tensor) – An N-D Tensor, the input data type should be bool.
axis (int|list|tuple, optional) – The dimensions along which the
logical andis compute. If
None, and all elements of
xand return a Tensor with a single element, otherwise must be in the range \([-rank(x), rank(x))\). If \(axis[i] < 0\), the dimension to reduce is \(rank + axis[i]\).
keepdim (bool, optional) – Whether to reserve the reduced dimension in the output Tensor. The result Tensor will have one fewer dimension than the
keepdimis true, default value is False.
name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.
logical andon the specified axis of input Tensor x, it’s data type is bool.
