6 years ago @TadasBaltrusaitis I've got the files now fully compiled with ./install.sh, but all binaries are causing Aborted (core dumped) or Segmentation faults ... not a single one will even get to the load "Reading the CNF landmark ..." part (!) any idea? Shall I downgrade from OpenCV 3.4 to 3.3 or even lower (4.0 does not compile at all)

6 years ago When u upgrade to 18.04 opencv 4.0 is downloaded when simply installing opencv via apt-get. Lib-jasper is not included / supported since Ubuntu 17.10 (!). On which (outdated?) version are u working on?

6 years ago I'm not working on Ubuntu, Windows is my dev machine. Can you link me to OpenCV 4.0, as I'm not able to find it, it seems like it will only be released in July 2018 earliest.
You seem to be having issues with OpenCV installation rather than OpenFace it seems.

6 years ago @TadasBaltrusaitis (1) OpenCV 4.0: link to OpenCV 4.0 https://github.com/opencv/opencv version.cpp shows 4.0.0 (which is then also installed as such) (2) OpenCV issues:

6 years ago Unfortunately that OpenCV version is still not a stable official release, but a work in progress. Have a look here - https://github.com/opencv/opencv/releases
Until it is an official release I am not planning on including it into OpenFace, but once it is I will make sure OpenFace works with it.
I don't know what the best solution for libjasper-dev is, but if it is not in Ubuntu 18, I imagine OpenCV 4.0 might not depend on it, or there will be workarounds for it, but we will need to wait a bit for that.

6 years ago although "not a stable official release", exactly this version 4.0.0 gets installed when entering "sudo apt-get install opencv" ... due to the hickups and instabilities, try to consider switching from Windows to LInux (Ubuntu et al) - I did that too after more than 25 years working with windows ... it's simply the more robust and stable platform where most code is running out-of-the-box. quite unfortunate that OpenFace is now (-) only supporting windows alone (-) with a heavily outdated description and now non-functioning linux distro and (-) the only solution proposal is "... wait with what happens ..." ...

6 years ago Just because it is installed with sudo apt-get install opencv it does not mean that the version is stable across other platforms (e.g. Windows) and the intention of OpenFace is to be cross platform, there is a reason it has not been propagated to the releases of OpenCV.
I will not get into a discussion on merits of Windows vs Linux :), but so far I had more issues with building OpenFace for Ubuntu rather than Windows (on which it runs out-of-the-box). This is probably because I am more experienced in the latter
OpenFace is cross-platform, it can successfully run on a number of Ubuntu flavors (tested on 14.04, 15.04, and 16.04) and OS X, and of course Windows.
Please note that this is a research project, mainly supported by one person, in my spare time, so you can't realistically expect it to run on all possible flavors of all OS's instantly. I will get round to Ubuntu 18.04 eventually, but there are some more pressing TODO's on the project before that.

6 years ago P.S. You are very welcome to create a pull request to make sure OpenFace works on newer versions of Ubuntu.
Also have you tried following these installation instructions https://www.pyimagesearch.com/2018/05/28/ubuntu-18-04-how-to-install-opencv/

6 years ago thx for the hint, but obviously, I'm too dumb to compile opencv under ubuntu 18.04 properly. I've added
-D CUDA_NVCC_FLAGS=--expt-relaxed-constexpr
to the cmake command as referenced in your link, but then I still got the following make error:

6 years ago @ewagner70 there is a docker image now available based off of Ubuntu 14.04. Do you really need Ubuntu 18?

6 years ago @fxfactorial I would like to mix it with other libraries (not just as pure playground) ... and most other MachineLearning libraries are up-to-date and not 3-4 major (unsupported) versions behind ... Thx anyway, I'm in the process of merging (python) libraries to one solution - gives more joy and speed than hunting compiler errors ...

6 years ago Is there something comparable to open face ?
