/// Computes the Euclidean norm of elements across dimensions of a tensor.
/// </summary>
/// <param name="input_tensor">The tensor to reduce. Should have numeric type.</param>
/// <param name="axis">The dimensions to reduce. If `None` (the default), reduces all dimensions.Must be in the range `[-rank(input_tensor), rank(input_tensor))`</param>
/// <param name="keepdims">If true, retains reduced dimensions with length 1.</param>
/// <param name="name">A name for the operation (optional).</param>
/// <returns>The reduced tensor, of the same dtype as the input_tensor.</returns>
