Please allow to use the external mkl-dnn installed as a package

[yurivict]

mkl-dnn packages exist on many systems: https://repology.org/project/mkl-dnn/versions

iDeep is fixed on specific MKL-DNN verions and rely it's own API set. If there is any discrepancy between them, things will go wrong. It's possible to detach iDeep building from MKL-DNN, it's head only library, technically it doesn't require "building". So what is your building environment? Can you elaborate it?

[yurivict]

My environment is building FreeBSD packages.

ideep currently installs its own version of mkl-dnn. Any other packages that might depend on the mkl-dnn port would conflict with ideep.

[CaoZhongZ]

OK, I'll have a check see if it is solvable.

@yurivict iDeep brings it's own MKL-DNN which install alongside within python directories, not /usr/local/lib. Other packages that depend on mkl-dnn port won't see the internal one. When dynamic linking I guess one of them will took the place and why would be a conflict? If you determined to use installed mkl-dnn, you could make mkl-dnn install more includes from its external directory, then it'll solve include file problem.

It's not along the python files.

OK, I'm asking what is your porting strategy. iDeep is a numpy extension enable MKL-DNN acceleration which used inside Chainer, which requires python setup process. However there were head only files could also provide a easier interface for MKL-DNN. Do you want both part? or just C++ API.
