mindspore.numpy.isneginf

mindspore.numpy.isneginf(x)[source]

Tests element-wise for negative infinity, returns result as bool array.

Note

Numpy argument out is not supported. Only np.float32 is currently supported.

Parameters: x (Tensor) – Input values.
Returns: Tensor or scalar, true where x is negative infinity, false otherwise. This is a scalar if x is a scalar.
Raises: TypeError – If the input is not a tensor.

Supported Platforms:: GPU CPU

Examples

>>> import mindspore.numpy as np
>>> output = np.isneginf(np.array([-np.inf, 0., np.inf, np.nan], np.float32))
>>> print(output)
[ True False False False]
