assertion failed (s.is_open())

[heaversm]

Hi - I got the assertion error that Kyle mentioned in the readme for facetracker. I'm assuming this has something to do with putting the model files in the proper place, but I can't seem to find where that place is. I have the standard face tracker examples working fine. I created a bin/data/model folder in the FaceSubstitution example, but that didn't seem to solve the issue.

if you're running the FaceSubstitution app, the files should be in FaceSubstitution/bin/data/model

for example, FaceSubstitution/bin/data/model/face.con etc.

Hmmm, that's where it's at. Something else must be wrong. I've successfully built ofxCV and ofxFaceTracker projects, but I wasn't sure what you meant: "finally switch out the source for the example you're interested in"

My overall structure is:

openFrameworks > addons > ofxFaceTracker > libs > Tracker > Tracker.h (etc, for the face tracker source) openFrameworks > apps > FaceSubstitution > Face Substitution (and Scramble Suit) > bin > data > model > face.con (etc, for the model files). This seems consistent with the XCode Project Config files.

that looks identical to my setup, so i'm not sure what the problem is. i recommend adding an ofDirectory and doing some kind of directory listing of the model/ folder to see if it has what you expect it to have.

[heaversm]

Ok, I'll work on it. Thanks for the quick response!

no worries -- also, i just remembered, there have been some seriously weird issues in the past with ofToDataPath() on different systems, different IDEs, etc. so if ofDirectory tells you that the folder doesn't exist, don't get too surprised -- just start trying to figure out where exactly OF thinks you are by listing "." first and working from there. and if you that it's giving you the wrong directory, definitely add a bug report to the OF issue tracker.

[heaversm]

Hey Kyle - so I did a diretory listing from testApp.cpp. Here is the code:

string path = "model/";

ofDirectory dir(path);

dir.listDir();

for (int i = 0; i < dir.numFiles(); i++){

    ofLogNotice(dir.getPath(i));

}

and the results seemed correct:

_OF: OF_LOGNOTICE: model/face.con

_OF: OF_LOGNOTICE: model/face.tracker

_OF: OF_LOGNOTICE: model/face.tri

_OF: OF_LOGNOTICE: model/face2.tracker

I did notice some very strange things happening in the assertion_failed error output though. It was sort of making up its own path names, or degrading names, or something. Here's the full error:

_Assertion failed: (s.is_open()),Assertion failed: (s.isopen()), function Load, file /Users/heav function Load, file /Users/heavers/Websource/openFrameworks/appers/Websource/openFrameworks/apps/FaceSubstitution/FaceSubstituts/FaceSubstitution/FaceSubstitution/../../../addons/ofxFaceTrackion/../../../addons/ofxFaceTracker/libs/Tracker/Tracker.cc, lineer/libs/Tracker/Tracker.cc, line 60.

• 60.*

Here's how I assume it should read though:

/Users/heavers/Websource/openFrameworks/appers/Websource/openFrameworks/ apps/FaceSubstitution/FaceSubstituts/FaceSubstitution/FaceSubstitution/../../../addons/ofxFaceTrackion/../../../addons/ofxFaceTracker/libs/Tracker/Tracker.cc, lineer/libs/Tracker/Tracker.cc* ???*

Crazy - misspellings and added path segments and stuff. If you have any idea why this is happening, I'd love to get to the bottom of it. Thanks again for your help.

this is really, really weird. i've really never seen anything like this before (path names getting glitched out) and i can only imagine that it has to do with some deeper error on your specific machine. if ofDirectory is listing the right files, but ofxFaceTracker can't load them, it makes me think there is some problem reading from disk.

[heaversm]

Yikes, well, I switched to a different computer and the good news is that I don't get weird path issues anymore, but the bad is that the error is still occurring. Are there any other files that might be missing that would trigger this error? What about the face images that are supposed to be substituted on to the face? I noticed that there was nothing within these two projects that looked like a jpg or anything. If you have any other ideas, let me know.

Hopefully this won't complicate anything (I'm really just trying to get face substitution working) but I ran a couple of the other examples in there, they threw errors in looking for a folder in ofxOpencv/libs/opencv/ called vs2010 (ex: vlibd.lib). I checked through the older versions of oF and couldn't find that folder. Seems like a reference to visual studio? Maybe that will give a clue to something that's missing in faceTracker as well.

Thanks again for your time and feedback.

Hi Kyle,

A couple other things - I updated the project settings (see screenshot) in xcode for face tracker and it now compiles, outputs (lldb) - and the app icon just bounces in my dock forever without actually running the program. I also tried to run scramble suit and got a number of errors - I wasn't quite sure where to change these settings, but they seem to be referencing something on your computer.

Hi Heaversm, I get the same issue in mac osx, but after I commented ofSetDataPathRoot("../data/"); in testApp.cpp I get it work. Thanks so much

[heaversm]

Removing the data path worked! Thanks.

[kylemcdonald]

ah wow, i never put these things together. sorry about this. the reason for the data path setting was so that you can "hide" the data inside the .app bundle. if you open up the downloaded (compiled) .app from the downloads section, you can see where i dropped the files inside the bundle. unfortunately this means it has a different file organization than the other examples, so it's a little surprising...
