You should find change the file located under "Desktop" in QtSDK folder. I mean, remember there are multiple Qt versions for the multiple targets (desktop, simulator, harmattan are some) under your QtSDK folder.

(1) find the right conf file for g++ on mac in your QtSDK folder. I've also installed OpenCV 2.4.2 using MacPorts.
It seems there's a small configuration problem with Qt 4.7.4 (my QtCreator's about window says it's 4.7.4, but the version I installed was 4.8.1, though!) and gcc on the new Mac OS X 10.8 Mountain Lion. Head to our guide on using Jupyter notebooks with your M1.I was having exactly the same issue reported by mjepson and tvdev. Run a Jupyter notebook on Apple M1 MacĪ next step of your journey using an Apple M1 Mac will likely involve using Jupyter notebooks. This is why the conda-forge opencv package is recommended. This is caused by the incompatible, amd64, version of ffmpeg being installed and then trying to be loaded by OpenCV. Library not loaded: /opt/homebrew/opt/ffmpeg/lib/libavcodec.58.dylib Miniforge specifically supports arm64 and will always grab arm64 versions that have been precompiled to run on m1. So it “works” it is just finicky and error prone.

The problem is that pip does not always install the arm64 version and instead tries to use rosetta to run amd64 versions which breaks. Be advised - pip has a package that can work. Why can't I install OpenCV on the M1 with PIP?Įven after you read the above, you might still want to install OpenCV on your M1 with PIP. To keep further dependencies in this environment, just install them after you activate the environment using the conda install command. Now every time you want to use opencv you can use the “cv” conda environment by using with the command conda activate cv. Lastly, we can install OpenCV conda install -c conda-forge opencv Next we can set up a new virtual environment called cv with python 3.8.6. Then we install miniforge using Homebrew. Installing Homebrew /bin/bash -c "$(curl -fsSL )" Homebrew is a dependency manager for MacOS, and we will use it to install miniforge. The first step is to install Homebrew if you don’t have it. Conda-forge provides community packages for Anaconda which has a much larger library of arm64 compatible packages. Instead, we use miniforge, a community package that provides a minimalistic Anaconda install and uses the conda-forge branch to install packages. One of the most popular packages to accomplish this is Anaconda, but anaconda is bloated and doesn’t always have the right packages for m1.
Virtual environments are a great way to separate different dependencies if you need different versions for different projects or if you don’t want to change your system path and its dependencies. To solve this inconsistency, we use virtual environments in miniforge. On M1 this is a problem and instead we want to the arm64 versions of OpenCV and its dependencies.

This means that most software is still built to run on amd64 processors so when we install OpenCV, there is a strong chance your computer, or dependency manager, tries to install an amd64 version. However, computers using arm64 processors are a very small subset compared to the billions of amd64 computers that have been around for the last 15 years. Macs with M1 processors use the arm64 architecture which is incompatible with the amd64 architecture used by the likes of Intel and AMD. Its dependency list includes packages like ffmpeg, libgfortran, and pixman which is where the issues start, especially for the M1.
OpenCV is a large library with a lot of dependencies though. It provides a large set of image manipulation tools that are very useful for processing images and image streams often for use with machine learning algorithms.
OpenCV is one of the most popular computer vision libraries.
