### Install OpenCV

We need to install the latest OpenCV version. Unfortunately, it is not available in the repositories. We are going to install it directly by using pip.
|
||||
|
||||
First, we need to install the needed dependencies, then we will directly install opencv:
|
||||
```sh
|
||||
sudo apt install libgtk-3-0 libavformat58 libtiff5 libcairo2 libqt4-test libpango-1.0-0 libopenexr23 libavcodec58 libilmbase23 libatk1.0-0 libpangocairo-1.0-0 libwebp6 libqtgui4 libavutil56 libjasper1 libqtcore4 libcairo-gobject2 libswscale5 libgdk-pixbuf2.0-0 libhdf5-dev libilmbase-dev libopenexr-dev libgstreamer1.0-dev libavcodec-dev libavformat-dev libswscale-dev libwebp-dev libatlas-base-dev
|
||||
sudo pip3 install opencv-contrib-python==4.1.0.25
|
||||
```
|
||||
|
||||
You can now check that opencv is properly installed by running a python interpreter and importing the cv2 module.
|
||||
```sh
|
||||
pi@planktoscope:~ $ python3
|
||||
Python 3.7.3 (default, Dec 20 2019, 18:57:59)
|
||||
[GCC 8.3.0] on linux
|
||||
Type "help", "copyright", "credits" or "license" for more information.
|
||||
>>> import cv2
|
||||
>>> cv2.__version__
|
||||
'4.1.0'
|
||||
>>> quit()
|
||||
```
|
||||
|
||||
If all goes well, the displayed version number should be `4.1.0`.
|
||||
