Solve the following python programming problem given the following code:
@ lower ('np.random.weibull', types.Float) 
def weibull_impl(context, builder, sig, args) : 
    _random = np.random.random 
    _log = math.log 
    def weibull_impl(beta) : 
        u = (1.0 - _random ()) 
        return ((- _log (u)) ** (1.0 / beta)) 
res = context.compile_internal (builder, weibull_impl, sig, args) 
    return impl_ret_untracked (context, builder, _random.return_type, res) 

    
    

    Fix the buggy line: return impl_ret_untracked (context, builder, _random.return_type, res)

#Here is Python program to fix the buggy line: return impl_ret_untracked (context, builder, _random.

return impl_ret_untracked (context, builder, sig.return_type, res)
