MKL not supported For Mac Osx #429

Closed ZE0TRON closed 6 years ago

ZE0TRON commented 6 years ago

By following the steps in ReadMe.md we can end up with the error /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/neon/backends/mklEngine/mklEngine.so: unknown file type, first eight bytes: 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00 while using python3. ReadMe.md can be updated with the info that MKL is not supported For Mac Osx so while using python3 people should use -b cpu or -b gpu parameters(default is mkl).

@ZE0TRON Currently neon with Intel Architecture optimizations (w/ Intel MKL Integration) do not support MacOS -- although Intel Math Kernel Library (MKL) already supports MacOS. The reason you saw the above was because neon by default download Linux MKL, while MacOS MKL is available from a similar URL https://github.com/01org/mkl-dnn/releases/download/v0.11/mklml_mac_2018.0.1.20171007.tgz (you can change prepare_mkl.sh or download_mkl.sh) but compiling on MacOS that supports Clang OpenMP is probably the hurdle

Turned out using gcc might work on Mac for enabling MKL. Please stay tuned.
