Do this by typing: conda create -n p3workshop python3.7 ipykernel jupyter anaconda. So if you install Python from the official binaries for Mac OS X or Windows platform, you are good to go with Tkinter. It can get confusing and you may accidently install a package to one version of Python while your IDE is using a different version. WeвЂ™re going to make a new environment called p3workshop. In addition to the system Python 2 and Python 3, you can also have Python 3 installed from the official installer as well as Homebrew's Python 3 all at once. On Windows, open Anaconda Navigator and start an Anaconda prompt. bash_profile, but still python is only 3.6: $ python -V Reinstall python and python3 via homebrew. On a Mac, open a Terminal from Applications > Utilities.

What worked for me was to resize the image instead of the window (I never did manage to get window resizing to work): import cv2 To celebrate OpenCV 3.0, I have decided to perform a series of blog posts that detail how to install OpenCV 3.0 on both Python 2.7+ and Python 3+. namedWindow('Image', WINDOW_NORMAL) Д¬heck the namedWindow function documented here In this case you can run python3 on your terminal to check the exact version installed, and if itвЂ™s recent enough you might be already set up. If you install Xcode, the Apple Development IDE, it installs Python 3 in /usr/bin/python3. This will allow you to resize your window. macOS installs Python 2 (outdated) by default, for compatibility reasons, making it available as /usr/bin/python. You can use the WINDOW_NORMAL flag when calling the namedWindow function as shown below. Simply write cv2.namedWindow('main', cv2.WINDOW_NORMAL)ДЄnd then manually resize it to your desired size cv2.resizeWindow('image', 900, 900) install OpenCV with Qt backend support and use cv2.namedWindow('main', CV_WINDOW_NORMAL).Once you have Homebrew set up, run the following command to. If you dont have Homebrew installed on your Macbook, you can install Homebrew on your MacOSX and then use it to install Python 3.8 on your machine. But the version of Python 3 that is installed is not the most recent. We will use Homebrew to install Python 3.8 and will then move on to creating a virtual environment.

So we have both versions of Python installed. use cv2.resize function to resize the image to desired size prior to displaying the image Now, letвЂ™s use another command to check if we have Python 3 installed.Yes, unfortunately you can't manually resize a nameWindow window without Qt backend.
