Hi,
I’m new to MXNet and I’m trying to run de C++ examples in incubator-mxnet/example/image-classification/predict-cpp directory.
When running without any modification, it works well, I’ve got the following output:
$ ./image-classification-predict ~buildbot/imagenet/ILSVRC2012_img_val/ILSVRC2012_val_00000001.JPEG

After changing the mode from cpu to gpu (dev_type = 2 line 201), I’ve the following error:

For informatuion, I compiled with
make USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/net/atlas/volume1/shared/opt/nvidia/cuda_9.2-cudnn_7.3/ USE_CUDNN=1 USE_CPP_PACKAGE=1 -j12
Thanks,
