Implementing kernel
C++ engine symbols that back this Python API.Element-wise NaN check.
Returns a boolean tensor that is True where the entry is NaN. The only IEEE 754 value that is not equal to itself.
Parameters
inputTensorInput tensor.
Returns
TensorElement-wise result with the same shape as input.
Notes
Mathematical definition:
Output dtype is bool. Not differentiable.
Examples
>>> import lucid
>>> x = lucid.tensor([1.0, 2.0, 3.0])
>>> lucid.isnan(x)
