dlib dnn_mmod_face_detection_ex 调用GPU 内存不够

PS D:\work\book\new Book\MachineLearn(DeepLearn)\OpenSourceFramework\dlib\dlib-master\examples\build\Release> .\dnn_mmod_face_detection_ex.exe .\mmod_human_face_detector.dat .\hj\hj_small.jpg
Error while calling cudaMalloc(&data, n) in file D:\work\book\new Book\MachineLearn(DeepLearn)\OpenSourceFramework\dlib\dlib-master\dlib\dnn\cuda_data_ptr.cpp:28. code: 2, reason: out of memory

即使非常小的图片也是如此

dnn example GPU memory 最小4G，如果处理dnn mmod face dectect 推荐1080 Ti 8G memory

(dlib dnn 推荐1080Ti )
