I can reproduce the bug now. I'm working on a fix for the bug. Currently, there are a few more bug fixes for MKLDNN. https://github.com/apache/incubator-mxnet/pull/10651 https://github.com/apache/incubator-mxnet/pull/10624 https://github.com/apache/incubator-mxnet/pull/10619/files https://github.com/apache/incubator-mxnet/pull/10616 https://github.com/apache/incubator-mxnet/pull/10591/files
They are ready for review. I just discussed with @Anirudh. Maybe we should say in the release note that MKLDNN in MXNet is still experimental. What do you think?

Are there any instructions of compiling these scala code? I guess I might miss some packages. I tried installing libslf4j-java and didn't help.

However I do not understand what you mean by 'set as CPU and not GPU'? MXNet compiled with mkldnn and cuda is supposed to be able to work with both context no? There are other tutorials that are running successfully on both CPU and GPU context. @Da to reproduce: Download the source of 1.2.0.rc0 and extract it, cd into it. make docs make clean make -j $(nproc) USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1 USE_MKLDNN=1 export PYTHONPATH=$(pwd)/python cd tests/nightly python test_tutorial.py --tutorial onnx/super_resolution you can also start a jupyter notebook server and try to run docs/_build/html/tutorials/onnx/super_resolution.ipynb 2018-04-21 15:08 GMT-07:00 Zheng, Da <[email protected]>: > @ThomasDelteil could you show me how to reproduce the problem?
