the cv virtual environment, we first need to match the link to our site-packages directory:
$ cd ~/.virtualenvs/cv/lib/python2.7/site-packages/$ ln -s /usr/local/lib/python2.7/site-packages/cv2.so cv2.so$ ln -s /usr/local/lib/python2.7/site-packages/cv.py cv.py
Step 11:
Finally, let's test the installation of OpenCV and Python:
$ workon cv$ python>>> import cv2>>> cv2.__version__'2.4.10'
OpenCV and Python have been successfully installed on your Raspberry

Raspberry Pi 2: less than 1 minuteStep 10:
At this step, OpenCV should have been installed in/usr/local/lib/python2.7/site-packages.
However, to use OpenCV in the cv virtual environment, we first need to match the link to our site-packages directory:

As for how to burn Raspberry Pi's system to the SD card, we will not continue to talk about it here. There are many introductory articles to explain and explain. This article mainly introduces how to build a programming platform that facilitates interaction with the Windows platform, and operate GPIO

Raspberry Pi backup and Raspberry Pi backup
We strongly recommend that you regularly back up important files. Backup is usually not limited to user files, but also configuration files, databases, installed software, settings, and even system snapshots.
Here we will guide you through some backup technologies to back up
after the first two steps our Raspberry Pi has worked normally, but before actually using it to develop some column configuration and software installation, so that the development will be handy, below we introduce the common software and services1.
