shoubhik opened a new issue #16177: How to dump quantized weights from MKLDNN as Ndarray URL: https://github.com/apache/incubator-mxnet/issues/16177 Hi, I have a use case where i need to debug the weights of Convolution layer when quantized by MKLDNN in MXNet [here](https://github.com/apache/incubator-mxnet/blob/master/src/operator/subgraph/mkldnn/mkldnn_conv.cc#L189-L190). The problem I am facing is that the model saved has the original fp32 weights and it is converted to int8 during runtime. When I do try to dump the cached_weight_ into a File as NDArray it is computed asynchronously and I get an error saying the weight is unavailable. The code I am using is something like this ``` LOG(INFO) << "Writing cached integer weight file"; char cwd[200]; getcwd(cwd, sizeof(cwd)); std::string current_dir(cwd); LOG(INFO) << "The current dir is : " << current_dir; LOG(INFO) << "Writing qunatized cached weights to file"; int num_args = 1; std::vector<NDArray> data(num_args); std::vector<std::string> names(num_args); data[0] = cached_weight_; names[0] = op_name; std::string cached_weight_file_path = current_dir + "/quantized-conv-weights/" + op_name; std::unique_ptr<dmlc::Stream> fo(dmlc::Stream::Create(cached_weight_file_path.c_str(), "w")); mxnet::NDArray::Save(fo.get(), data, names); LOG(INFO) << "Written weights to " + cached_weight_file_path; ```
