Movement on Python API?

[fxfactorial]

Looks like there are two open PRs

#217

#207

for adding a python API.

@TadasBaltrusaitis is there a reason for delay? I can also do the python bindings as a fresh PR if need be.

The interface of OpenFace has changed quite a bit since the original PRs. I want to add the binding eventually, but other additions to OpenFace came first.

The OpenFace you link to is quite a different project, it does face recognition rather than landmark detection and facial behavior analysis.

Oh interesting, so to pick up emotions like angry or sad, then this lib is more appropriate ? If so, then I could still volunteer to get the bindings done, assuming my work will have use for it.

Yes, this OpenFace is much more suitable for emotion recognition.

If you were to create python bindings I would include them into the main repo! However, I would wait for a week or two as I will be releasing OpenFace 2.0 very shortly and that will change the interface a bit.

@TadasBaltrusaitis Okay great, then I'll wait a bit till you reorganize it as you want. Appreciate your quick replies.

[TadasBaltrusaitis]

I have updated the OpenFace version and the interface should be reasonably stable now.

The python interface about Aus recognition can also be updated? Thansk for your reply!

@fxfactorial @TadasBaltrusaitis dear gentlemen, any progress on openface 2.0 python APIs?
By the way, how do i get OpenFace 2.0 run on ubuntu (windows has become significantly less useful in the past 1-2 years)

[TadasBaltrusaitis]

Hi, for instructions on how to install on Ubuntu, please have a look here: https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation

Currently I'm not working on the python API.

[ewagner70]

@TadasBaltrusaitis Minor misunderstanding. The installation was not a (big) problem. I don’t know how to use it (the files are windows cpp files with vcx project files. How shall we compile/test/run openface on Ubuntu AFTER installation? There are no python files for testing, correct?

[TadasBaltrusaitis]

Sorry, I'm still not exactly sure what the question is. What do you mean how to use it? The .cpp files are not operating system specific. Cross-platform building is done using CMake (for OSX and Ubuntu) and Visual Studio solution files for Windows.

Compilation on Ubuntu is described in the wiki page I linked to (https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation), it also lists some example tests you can run to make sure building worked (https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation#actual-openface-installation).

Testing and running OpenFace after the compilation is done can be done through a command line interface described here - https://github.com/TadasBaltrusaitis/OpenFace/wiki/Command-line-arguments

@ewagner70 look in the build dir's bin directory for the executables to run.

I might return to doing a Python API if my current project continues (since I accomplished my other desired task directly in C++.)

@TadasBaltrusaitis @fxfactorial Thx for the hints, but what I get when trying to compile the cpp files is

any ideas? I'm running on Ubuntu 18.04 ...
