    (sorry if this is a double-post. after clicking the submit button my message never appeared, then when I go back to the forum site says “This is somewhat embarrassing, isn’t it? It seems we can’t find what you’re looking for.”).

    When I try to run the “FaceOSC_Wekinator” Mac binary application (inside the “VideoInput_FacialExpression_oF_14Inputs” folder) on my machine (High Sierra, 10.13.3), the application promptly crashes with the error “FaceOSC_Wekinator has quit unexpectedly.” The bug report is quite lengthy and I’m happy to provide it on request, but the core part of the report looks like a failed assertion:

    Application Specific Information:
    Assertion failed: (s.is_open()), function Load, file /Applications/of_v0.9.0_osx_release/addons/ofxFaceTracker/libs/FaceTracker/src/lib/, line 59.

    As an alternative, I was able to download the FaceOSC binary ( which actually does run (note that the lighting has to be pretty bright for it to detect a face), but despite telling Wekinator to listen to port 8338 instead of the default port, the input never connects, whether I choose 14 inputs (for pose + gesture) or 8 (gesture alone).


    Then instead, I switched to the “WebcamObject_4096Inputs” inputs, and after downloading the image-net-2012.sqlite3 file and putting it in the WebcamObject_4096Inputs/data/ directory, I nevertheless get the error “Network file not found! Check your data folder to make sure it exists.” …Yes, it does exist. Screenshot from Finder: Screenshot of WebcamObject_4096Inputs directory, showing presence of image-net-2012.sqlite3 file in data/ directory

    Then I thought I might try building the latter example from source, but the link in the README is bad:
    “This program uses Gene Kogan’s ConvnetOSC (”. Going to that URL gives a 404. The proper link is Seems there’s a rabbit-hole of installing openFrameworks, and ofxCcv, and who knows what other dependencies those may involve. Not gonna try.

    So…what to do now? I’m looking to run a webcam input more sophisticated than the smiley-face “VideoInput_FaceDetection_Processing_3Inputs” example (which works, by the way).

    …and customizing the address names of Wekinator’s input OSC messages to match those of FaceOSC ( “/gesture/mouth/width”, etc.) still had no effect: no input. Tried downloading the FaceOSC-Wekinator source to see where these messages were set, but it seems the downloads of the source, despite being on the FaceOSC-Wekinator page (, actually only give the source for the *regular* FaceOSC code, not the Wekinator version.

    Ok… This is my very first day trying to use any of this stuff, and I’m done trying. Please help me out.

    Hi there,

    Sorry for the delayed reply. There is an issue with openFrameworks-generated apps on High Sierra, specifically having to do with OS X Gatekeeper. This may be causing the problem you’re seeing.

    One easy fix is to move the app to another directory (e.g., to the desktop) and then back. Then try double-clicking on it again. If it’s the Gatekeeper issue causing your problem, this should fix it.

    No, that doesn’t work 🙁

    Scott, did this fix your problem?

    Jegama, can you describe what you are experiencing?
