mindspore.numpy.isnan
- mindspore.numpy.isnan(x, dtype=None)[source]
Tests element-wise for NaN and return result as a boolean array.
Note
Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported. Only np.float32 is currently supported.
- Parameters
x (Tensor) – Input values.
dtype (
mindspore.dtype
, optional) – defaults to None. Overrides the dtype of the output Tensor.
- Returns
Tensor or scalar, true where x is NaN, false otherwise. This is a scalar if x is a scalar.
- Supported Platforms:
GPU
CPU
Examples
>>> import mindspore.numpy as np >>> output = np.isnan(np.array(np.nan, np.float32)) >>> print(output) True >>> output = np.isnan(np.array(np.inf, np.float32)) >>> print(output) False
