Method 2: Install Opencv using pip on the whl file Otherwise, it will start downloading the package and install OpenCV. You can see I have already installed OpenCV on my computer. xx version pip3 install opencv-python Installing Pre-built OpenCV python module using pip xx version pip install opencv-pythonįor python 3. That’s why use according to it.įor python 2. However, I am showing you how to install it on both python versions, python 2. Therefore make sure you check the python version using the following command. You should also remember that the pip command differs for different python versions.
