ghgggg opened a new issue #12215: using C++ api in windows10 to extract feature error URL: https://github.com/apache/incubator-mxnet/issues/12215 i'm just using mxnet C++ api to extract feature ,show the codes below cv::Mat img = _img.getMat(); img.convertTo(img, CV_32F); img = (img - 127.5) / 128; static NDArray input(Shape(1, img.channels(), img.rows, img.cols), ctx); // NDArray temp(Shape(1, img.channels(), img.rows, img.cols), Context(kCPU, 0),false); NDArray::WaitAll(); auto ptr = temp.GetData(); std::vector<cv::Mat> chs(3); for (int i = img.channels() - 1; i >= 0; i--) { chs[img.channels() - i - 1] = cv::Mat(img.size(), CV_32FC1, (float*)ptr + i*img.size().area()); } cv::split(img, chs); //input = temp.Copy(ctx); input.SyncCopyFromCPU(temp.GetData(), temp.Size()); NDArray::WaitAll(); return Extract(input); when ctx = Context(kGPU, 0); the code executor = net.SimpleBind(ctx, args_map, map<string, NDArray>(), map<string, OpReqType>(), aux_map); occurs error. but cpu mode all of them are OK. I don't know how to solve it ,anybody could help me ?thanks a lot
