If you want to learn more about OpenCV and Python I would recommend reading OpenCV with Python Blueprints by M. You need to move the window in order to see both images: By default, the last image (the gray one) will be over the first one. You should see something like in the next figure. (You can close the two windows by pressing ESC!)

#OPENING PYTHON ON MAC MAC OS X#
You do not want the Mac OS X 'default Python' to be 'python3.' You want to never care about default Python.' How do we stop caring about the default Moshe recommends using pyenv to manage Python environments (for a deeper dive on configuring pyenv, see this article. imshow ( "Over the Clouds - gray", gray ) 11 12 cv2. 'The basic premise of all Python development is to never use the system Python. imshow ( "Over the Clouds", img ) 10 cv2. In the same folder where you’ve saved the above image, create a new file demo.py and write the next code: 1 import cv2 2 3 print ( "OpenCV version:" ) 4 print ( cv2. We can write a small test program that will print the OpenCV version, load an image from the disk, convert the image to gray and show the result.

Please note that the above will install the slightly older OpenCV 4.1, latest binary version doesn’t seem to work on macOS Catalina!Īs a side note, when you are in a new environment you can use python to invoke the Python interpreter, no need to use the version number.Īt this point, you should have OpenCV 4 and Python installed on your Mac. Let’s take a quick look at how this tool works to fully delete Python on Mac. We can install NumPy and OpenCV with: 1 pip install numpy 2 pip install opencv-python=4.1.2.30 Open the Finder, and click on Applications in the sidebar to navigate to. As the Python website says, 'Python 2.x is legacy, Python 3.x is the.

If you want to be able to use it, use the source work/bin/activate command. This video explains how to install Python 3 in a Mac OS X, both Mavericks and Yosemite. By default, if you close your Terminal, the environment is deactivated. Once an environment is activated, all the install commands will apply only to the current environment. You can read more about Python environments in the documentation. Next, let’s follow best practices and create a new Python environment in which we can install NumPy and OpenCV: 1 python3.8 -m venv work 2 source work/bin/activateĪt this point, your prompt should indicate that you are using the work environment.

This is what I see if I run python3.8 on my machine: 1 % python3.8Ģ Python 3.8.1 (v3.8.1:1b293b6006, Dec 18 2019, 14:08:53) 3 on darwin 4 Type "help", "copyright", "credits" or "license" for more information. python3 will also invoke the latest installer version of Python 3. If this is the case, you can select which version you want to use by specifying the version number, e.g.: 1 python3.7Īfter the above, you can invoke Python 3.8 using the python3.8 command. You can also check the video version of this tutorial if you want to see how I did it.Īs a side note, you can have multiple Python 3 versions installed on your macOS machine. The official installer of Python is a pkg file that will start a GUI installer which will guide you through the installation. Once the Command Line Tools are installed, we can install Python. Open a Terminal and write: 1 xcode-select -install Please note, that you will need the Command Line Tools even if you’ve already installed Xcode. Start by installing the Command Line Tools for macOS.

In this tutorial, we’ll use the Python 3.8. Python 3.x is the future and it is supported by all major Python libraries. MacOS comes by default with Python 2.7 which, at this point, receives only bug fixes and will be EOL by 2020.
