Solve the following python programming problem given the following code:
def _start(self) : 
    network_start_d = defer.Deferred () 
    def setup_network() : 
        self.config = SimpleConfig () 
        self.network = Network (self.config) 
        alert.info ('Loading the wallet...') 
        return defer.succeed (self.network.start ()) 
d = setup_network () 
    def check_started() : 
        if self.network.is_connecting () : 
            if ((not self.printed_retrieving_headers) and self.network.blockchain.retrieving_headers) : 
                alert.info ('Running the wallet for the first time...this may take a moment.') 
                self.printed_retrieving_headers = True 
return False 
self._start_check.stop () 
        self._start_check = None 
        if self.network.is_connected () : 
            network_start_d.callback (True) 
else : 
            network_start_d.errback (ValueError ('Failed to connect to network.')) 
self._start_check = task.LoopingCall (self) 
    d.addCallback ((lambda _ : self._start_check.start (0.1))) 
    d.addCallback ((lambda _ : network_start_d)) 
    d.addCallback ((lambda _ : self._load_wallet ())) 
    d.addCallback ((lambda _ : self._get_cmd_runner ())) 
    return d 

    
    

    Fix the buggy line: self._start_check = task.LoopingCall (self)

#Here is Python code to fix the buggy line: self.
