mindspore.numpy.isinf
=================================
.. py:function:: mindspore.numpy.isinf(x, dtype=None)
逐元素测试是否为正无穷大或负无穷大。
返回一个与 ``x`` 具有相同shape的bool数组``x == +/-inf`` 时为True否则为False。
.. note::
不支持Numpy的 ``out````where````casting````order````subok````signature````extobj`` 参数。目前仅支持 ``np.float32``
参数:
- **x** (Tensor) - 输入值。
- **dtype** (mindspore.dtype, 可选) - 默认值: ``None`` 。覆盖输出Tensor的dtype。
返回:
Tensor或标量``x`` 为正无穷大或负无穷大时为True否则为False。如果 ``x`` 是标量,则返回标量。
