FATAL ERROR DETECTED - CUDA NOT ENABLED

CUDA 9.2 - I know this works with my OpenCV setup and with opencv4nodejs OpenBlas installed via sudo apt-get install libopenblas-dev face-recognition installed just via npm install - I couldn’t get custom dlib to work. The module installs fine as far as I can tell - it even mentions CUDA in the install and all seems ok!

My code works ok on my Macbook, although a little slow - I wanted to try it on my Ubuntu box with CUDA enabled GPUs

This is the error I get:

**************************** FATAL ERROR DETECTED ****************************

Error detected at line 120.
Error detected in file /home/analytics/code/cv-analytics-ws/node_modules/dlib-build/dlib/dlib/dlib/dnn/gpu_data.h.
Error detected in function float* dlib::gpu_data::device().

Failing expression was false.
CUDA NOT ENABLED

******************************************************************************

This is what I am doing:

const image = fr.cvImageToImageRGB(new fr.CvImage(cv.imread(tmpName).resizeToMax(1000)))

const detector = fr.FaceDetector();
const recognizer = fr.FaceRecognizer();
    
const targetSize = 150;
const faces = detector.detectFaces(image, targetSize) // this is what causes the error to happen

Any help would be great!

I think @legraphista was facing a similar issue. Also probably “DLIB_USE_CUDA” has to be defined in the define section of the gyp file.

Unfortunately I can’t test CUDA related stuff, so I am not sure how to properly compile this package with cuda.

You can declare preprocessor directives in the “defines” section. You probably compiled dlib with cuda, but the DLIB_USE_CUDA was missing, thus in some dlib header file included by face-recognition.js some code wrapped in #ifdef DLIB_USE_CUDA ... did not get compiled into the package, leading to a runtime error.
