Votre dll est-elle une dll qui peut tirer parti du multi-core?

Les utilisateurs d'OpenCV qui se soucient de «la lenteur de Python par rapport au C ++» devraient se préoccuper du contenu de la DLL et de la compilation cv2.pyd qu'ils utilisent. Avez-vous déjà utilisé un processeur multicœur, mais le contenu de la dll que vous utilisez sont des dll qui ne peuvent pas être utilisées?

buildIno.cpp

#include <opencv2/core/core.hpp>
#include <iostream>

int main(int argc, const char* argv[])
{
  //Afficher les informations de construction
  std::cout << cv::getBuildInformation() << std::endl;

  return 0;
}

La condition de cv2.pyd utilisée par Python est Vous pouvez le voir comme suit. >>> import cv2 >>> print cv2.getBuildInformation()
