I need to run a script which uses SIFT, with PyCharm. I must use the OpenCv 2.4.13, but I can’t install previous version than OpenCV 3.x using the PyCharm package installer. So I downloaded the OpenCV 2.4.13 folder, put it in my project folder and created a new Virtualenv Environment, adding the path to the OpenCV folder to the Python interpreter for that Virtualenv Environment, but I still can’t import cv2 getting the error “no module named cv2”.
What am I doing wrong?
