In this OpenCV tutorial, we learn how to install OpenCV with Anaconda using pip command, and then verify the installation using a simple Python code to read and display an image.
Install OpenCV Python with Anaconda
Anaconda is a good tool for Python application development. If you have anaconda installed, working with OpenCV becomes easier. You may follow: Install Anaconda tutorial if Anaconda is not installed yet.
To install OpenCV Python with Anaconda, use following pip command.
$ pip install opencv-python
$ pip install opencv-python Collecting opencv-python Downloading opencv_python-188.8.131.52-cp36-cp36m-manylinux1_x86_64.whl (24.9MB) 100% |????????????????????????????????| 24.9MB 35kB/s Requirement already satisfied: numpy>=1.11.3 in /usr/lib/anaconda3/lib/python3.6/site-packages (from opencv-python) Installing collected packages: opencv-python Successfully installed opencv-python-184.108.40.206
OpenCV package for Python is successfully installed.
Verify if OpenCV is installed
Following is a simple program to verify the OpenCV Python package. We shall use methods of cv2 to read and display an image.
import cv2 img = cv2.imread('/home/img/python.png') cv2.imshow('image',img) cv2.waitKey(0) cv2.destroyAllWindows()
When you run the above example, the following image would be displayed in a separate window.
