traincascade error - _cascadeDirName or _bgfileName or _vecFileName is NULL
Hi,
I am trying to train a cascade classifier with opencv_traincascade, but I keep getting the error:
_cascadeDirName or _bgfileName or _vecFileName is NULL
The specific command I am using is:
./opencv_traincascade vec ~/Documents/Kaggle/whale_faces.vec -data ~/Documents/Kaggle/cascadetrain -bg ~/Documents/Kaggle/negatives/bg.txt -numPos 10 -numNeg 50
And I get the error:
``` OpenCV Error: Bad argument (_cascadeDirName or _bgfileName or _vecFileName is NULL) in train, file /tmp/opencv20150810-26088-1150u2z/opencv-2.4.12/apps/traincascade/cascadeclassifier.cpp, line 146 libc++abi.dylib: terminating with uncaught exception of type cv::Exception: /tmp/opencv20150810-26088-1150u2z/opencv-2.4.12/apps/traincascade/cascadeclassifier.cpp:146: error: (-5) _cascadeDirName or _bgfileName or _vecFileName is NULL in function train
Abort trap: 6 ```
All of the folders and files are valid. I am able to view the vec file with opencv_createsamples.
Does anyone know how I might fix this error? Thanks for the help.
