mindspore.amp.all_finite
- mindspore.amp.all_finite(inputs, status=None)[source]
Returns a scalar Tensor indicating whether the inputs are finite.
Note
This is an experimental interface that is subject to change or deletion.
The interface must be used in whole network training scenario to detect whether grads are finite, and the results may be different on different device targets.
- Parameters
- Returns
Tensor, a scalar Tensor and the dtype is bool.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> x = (Tensor(np.array([np.log(-1), 1, np.log(0)])), Tensor(np.array([1.0])) >>> output = amp.all_finite(x)
