How to install Opencv-Python 3.4.7.28 using pip
I tried to import cv2 for my python script but, there is no cv2 module. After some google search, I found that "python -m pip install opencv-python" will works for me but, it installs opencv4 not opencv3. So, I searched google again and found that some conditions for pip command. $>python -m pip install "opencv-python==3.4" then I got this message: ERROR: Could not find a version that satisfies the requirement opencv-python==3.4 (from versions: 3.4.2.16, 3.4.2.17, 3.4.3.18, 3.4.4.19, 3.4.5.20, 3.4.6.27, 3.4.7.28, 4.0.0.21, 4.0.1.23, 4.0.1.24, 4.1.0.25, 4.1.1.26) ERROR: No matching distribution found for opencv-python==3.4 So I typed, $>python -m pip install "opencv-python==3.4.7.28" Collecting opencv-python==3.4.7.28 Downloading https://files.pythonhosted.org/packages/db/97/7d04b67cfdc3588c38ed16c92c372a6f682953086b31fd7cefaa9a4a260e/opencv_python-3.4.7.28-cp37-cp37m-win32.whl (26.5MB) |████████████████████████████████| 26.
