mindspore.numpy.logical_or(x1, x2, dtype=None)[source]

Computes the truth value of x1 OR x2 element-wise.


Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported.

  • x1 (Tensor) – Input tensor.

  • x2 (Tensor) – Input tensor. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

  • dtype (mindspore.dtype, optional) – Defaults to None. Overrides the dtype of the output Tensor.


Tensor or scalar, element-wise comparison of x1 and x2. Typically of type bool, unless dtype=object is passed. This is a scalar if both x1 and x2 are scalars.

Supported Platforms:

Ascend GPU CPU
