chenbiaolong opened a new issue #8360: How to bind different input shape to 
executor in c++?
URL: https://github.com/apache/incubator-mxnet/issues/8360
 
 
   I build a cnn network to extract images feature, however my input images do 
not have same shape,eg:
   [batch, 1, 32, width], `batch` and `width` can change at each forward. so 
how can I bind different input data to an executor? One solution is rebind 
executor every time I run forward, but it cost too much time. Any example code 
solve this problem? my code now:
   ```
    int MXNetInference::GetOutputTensor(
                       const std::map<std::string, mxnet::cpp::NDArray>& inputs,
                       std::vector<mxnet::cpp::NDArray>& outputs) {
           for(auto& input: inputs) {
               args_map_[input.first] = input.second.Copy(*global_ctx_);
               NDArray::WaitAll();
           }
           /*bind the excutor*/
           executor_.reset(net_.SimpleBind(*global_ctx_, args_map_, map<string, 
NDArray>(),
                   map<string, mxnet::cpp::OpReqType>(), aux_map_));
           executor_->Forward(false);
           /*print out the features*/
           std::vector<NDArray> results = executor_->outputs;
           for(auto& result: results) {
               NDArray array = result.Copy(Context(kCPU, 0));
               NDArray::WaitAll();
               outputs.push_back(array);
           }
           return 0;
       }
   ```
