mindspore.numpy.isfinite
=================================
.. py:function:: mindspore.numpy.isfinite(x, dtype=None)
逐元素测试是否为有限数(不是无穷大或非数值)。
结果将以bool数组的形式返回。
.. note::
不支持Numpy的 ``out````where````casting````order````subok````signature````extobj`` 参数。在GPU上支持的dtype为 ``np.float16````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或标量如果 ``x`` 不是正无穷大、负无穷大或NaN则返回为True否则为False。如果 ``x`` 是标量,则返回标量。
