nanmin(a, axis=None, dtype=None, keepdims=False)¶
Returns the minimum of array elements over a given axis, ignoring any NaNs.
Numpy arguments out is not supported. For all-NaN slices, a very large number is returned instead of NaN. On Ascend, since checking for NaN is currently not supported, it is not recommended to use np.nanmin. If the array does not contain NaN, np.min should be used instead.
mindspore.dtype, optional) – defaults to None. Overrides the dtype of the output Tensor.
keepdims (boolean, optional) – defaults to False. If this is set to True, the axes which are reduced are left in the result as dimensions with size one. With this option, the result will broadcast correctly against the original a.
ValueError – if axes are out of the range of
[-a.ndim, a.ndim), or if the axes contain duplicates.
- Supported Platforms:
>>> import mindspore.numpy as np >>> a = np.array([[1, 2], [3, np.nan]]) >>> output = np.nanmin(a) >>> print(output) 1.0 >>> output = np.nanmin(a, axis=0) >>> print(output) [1. 2.]
