docstring: Performs an element-wise check to determine if the NDArray contains a NaN element
      or not.
  
  
      Parameters
      ----------
      input : NDArray
          An N-D NDArray.
  
      Returns
      -------
      output: NDArray
          The output NDarray, with same shape as input, where 1 indicates the array element is
          NaN i.e. Not a Number and 0 otherwise.
  
      Examples
      --------
      >>> data = mx.nd.array([np.nan, -1])
      >>> output = mx.nd.contrib.isnan(data)
      >>> output
      [1. 0.]
      <NDArray 2 @cpu(0)>
