1. Install Python3
1.1 In Windows
Scientific programming in Python requires multiple third-party packages (like numpy), whose installing procedure needs complicated compiling tools. Those compiling tools are tricky in Windows. Anaconda is the most popular Python data science platform, which includes essential pre-compiled third-package packages. Thus, in Windows platform, we suggest installing Python by Anaconda.
Visual Studio Vb Examples
Download and install Anaconda Python 3.7 from official website. Plase check adding to system path while installing.
In order to test the Anaconda. Open command line PowerShell. If the installed Anaconda is the only Python version in your operating system. Type python. In If it shows:
Visual Studio Code Opencv
Then type exit() and enter. Type pip -V. If the screen shows:
Congratulations! Your Anaconda environment is successfully installed in your Windows.
If you have another version of Python, try python3 / py3 and pip3 instead.
1.2 In Linux (like Ubuntu)
In general, Python is pre-installed in Ubuntu. For Ubuntu 18.04, in Terminal, you can type python3 to enter python console mode.
If your Ubuntu does not have Python3, please try:
to install Python3.
We also need pip to maintain Python third-party packages. Use
to install pip3.
You can also install Anaconda in Linux if you want.
2. Install OpenCV3
OpenCV is the most popular open source computer vision libraries. We will use pip to install OpenCV for Python. Please type pip -V in command line to check the current pip is matched to your target Python version. You may use pip3 instead (In Ubuntu 18.04).
In command line, type pip install opencv-python.
To test OpenCV, in python consle mode, type the following codes in order.
