tensorplay.functional.isnan

tensorplay.functional.isnan(input) → Tensor[source]

Returns a new tensor with boolean elements representing if each element of input is NaN or not. Complex values are considered NaN when either their real and/or imaginary part is NaN.

Parameters:

input (Tensor) – the input tensor.

Returns:

A boolean tensor that is True where input is NaN and False elsewhere

Example:

>>> tensorplay.isnan(tensorplay.tensor([1, float('nan'), 2]))
tensor([False, True, False])
