WebOct 16, 2024 · To check for NaN values in a Numpy array you can use the np.isnan () method. This outputs a boolean mask of the size that of the original array. np.isnan (arr) Output : [False True False False False False True] The output array has true for the indices which are NaNs in the original array and false for the rest. 4. Equating two nans Webtorch.isnan(input) → Tensor. 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 ...
