I set up a virtualenvs for python 3.1 with opencv3. But when I am in the virtual env and execute python import cv2. Apparently you have to create a link of the 3.1.so file to cv2.so . I get an error relating to cv2 /opt/ros/kinetic . I do not know why it is looking here? If I uninstall ros then it works fine, no error. Any thoughts. Update: if I remove the .bashrc source kinetic setup then it also works fine in the virt. What ever the setup is doing is causing a conflict even when the ros is set up outside the virtual env.

Try this: reinstall opencv3 while in the virtualenvs and specify the target install path to your virtualenvs opencv3 desired directory using CMAKE_INSTALL_PPREFIX=/your/desired/venv/directory

Thanks....I will keep this i mind for future reference. Right now I can use both enviroments by just commenting on/off the source lines in the .bashrc file.
