    my code like this：


#include<CL/sycl.hpp>

void p(size_t number_bands){
gpu_selector selector;
  queue q(selector);
auto R = range(20);
buffer number_bands1(number_bands,R);
q.submit([&](handler& h){
accessor number_bands2 (number_bands1,h,read_only);
        h.parallel_for(range<1> (number_bands2),[=](id<1>n1){
                    "code"
              });
       });
}

int main(){
p(2);
}
