songziqin opened a new issue #14152: data layer grad problem
URL: https://github.com/apache/incubator-mxnet/issues/14152
 
 
   the C++ code as follows:
    args_["data"] = NDArray(Shape(params.batch_size, params.dim), ctx);
    network_.InferArgsMap(ctx, &args_, args_);
    exec_.reset(network_.SimpleBind(ctx, args_));
   
   I find the exec_.get()->grad_dict() get the data layer grad is all 0.
   and I want to know through the code above, can I  get the actual 
   the data layer grad. thanks.
