mindspore.numpy.isfinite
- mindspore.numpy.isfinite(x, dtype=None)[source]
Tests element-wise for finiteness (not infinity or not Not a Number).
The result is returned as a boolean array.
Note
Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported. On GPU, the supported dtypes are np.float16, and np.float32.
- 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 not positive infinity, negative infinity, or NaN; false otherwise. This is a scalar if x is a scalar.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore.numpy as np >>> output = np.isfinite(np.array([np.inf, 1., np.nan]).astype('float32')) >>> print(output) [False True False]
