Good day everyone, thanks for taking the time to look into my question. I've started implementing an ANN classification based on OpenCV but I have this error:

• error LNK2019: symbole externe non résolu "public: static class cv::Ptr<class cv::ml::ann_mlp=""> __cdecl cv::ml::ANN_MLP::create(void)" (?create@ANN_MLP@ml@cv@@SA?AV?$Ptr@VANN_MLP@ml@cv@@@3@XZ) référencé dans la fonction main C:\Users\PC\Desktop\essais pour type de tumeur\essai 18\opencv_test\opencv_test.obj
• error LNK1120: 2 externes non résolus

Thanks you for your help.
