Ich bin neu bei Ubuntu und OpenCV. Ich versuche dieses Tutorial zu verwenden, um loszulegen. Doch in den Schritten 7 und 8 Ich kann nicht pip
installieren:kann nicht installieren pip virtualenv virtualenvwrapper opencv3 python2.7 ubuntu
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
Was soll ich tun? Ich erhalte diesen Fehler:
