Solve the following python programming problem given the following code:
@ lower ('np.random.power', types.Float) 
def power_impl(context, builder, sig, args) : 
    def power_impl(a) : 
        if (a <= 0.0) : 
            raise ValueError ('power(): a <= 0') 
return math.pow ((1 - math.exp ((- np.random.standard_exponential ()))), (1.0 / a)) 
res = context.compile_internal (builder, power_impl, sig, sig) 
    return impl_ret_untracked (context, builder, sig.return_type, res) 

    
    

    Fix the buggy line: res = context.compile_internal (builder, power_impl, sig, sig)

#Here is Python code to fix the buggy line: res = context.

res = context.compile_internal (builder, power_impl, sig, args)
