Solve the following python programming problem given the following code:
@ gof.local_optimizer ([sigmoid]) 
def local_hard_sigmoid(node) : 
    if (isinstance (node.op, tensor.Elemwise) and (node.op.scalar_op == scalar_sigmoid)) : 
        out = hard_sigmoid (out.inputs [0]) 
        def values_eq_approx_remove_low_prec(a, b) : 
            return tensor.TensorType.values_eq_approx (a, b, atol = 0.1) 
out.tag.values_eq_approx = values_eq_approx_remove_low_prec 
        return [out] 

    
    

    Fix the buggy line: out = hard_sigmoid (out.inputs [0])

#Here is Python code to fix the buggy line: out = hard_sigmoid (out.

out = hard_sigmoid (node.inputs [0])
