Linux needs the python3-xlib (or python-xlib for Python 2) module installed. macOS needs the pyobjc-core and pyobjc module installed (in that order). Don't want to print all of the output, so here is just the Error message. The Win32 extensions do not need to be installed. I downloaded opencv-3.1.0 from here unzipped it and ran: python platforms/osx/build_framework.py osxįrom the opencv-3.1.0 directory. How to install opencv-python 4.5.1-dev in Mac Python build, apple JianWang February 18, 2021, 5:13pm 1 I was using pip install opencv-contrib-python to install the packages which contain both main modules and contrib/extra modules. I am trying to install opencv-3.1.0 to use with python 2.7. This should correctly link your cv2.so file thus resulting in removing this error.I recently upgraded to MacOS Sierra and I have been dealing with many issues (I am mentioning it cause it may be relevant). Get new MacBook Pro 2017, then installed anaconda, and installed opencv using conda (conda install -c conda-forge opencv). After installation open XCode, and accept xcode-build license when it asks. Search for xcode and download the version compatible to your OS. Ln -s -f /usr/local/Cellar/opencv/2.4.12/lib/python2.7/site-packages/cv2.so /usr/local/lib/python2.7/site-packages/cv2.so Go to this webpage Login if you have apple developer account else create your account and login. Try uninstalling and reinstalling opencv again (b) Your opencv installation may have issues. If this file does not exist then (a) Your versions may be different, so change that accordingly.

Ls -l /usr/local/Cellar/opencv/2.4.12/lib/python2.7/site-packages/cv2.so Check your python packages for opencv from brew directory.If this is the case, your cv2.so needs to be linked. Sayak Paul 4 min read opencv installation m1 Install Xcode and Homebrew Install conda Install NumPy Compile OpenCV Sym-link OpenCV 4 on macOS to virtual environment site-packages References This post shows how to build and install OpenCV 4.5.0 on a MacBook Pro that comes with an M1 chip. I finally decided to use virtualenv to handle packages by each python project. Because, mac os block too many directories to install. Ls -l /usr/local/lib/python2.7/site-packages/ģ056 -rwxr-xr-x 1 admin 1563612 Oct 23 00:33 cv2.so Use the sudo -H flag and/or use the ignore-installed flag: sudo -H pip install -ignore-installed opencv-python. On top of that installing and linking all site-packages is little problematic and we end up with errors. Problem with Mac is Python 2.7 is already installed by Mac. NOTE: PyTorch LTS version 1.8.2 is only supported for Python < 3.8. Dont use linux steps to instal opencv-python on Mac. conda conda install pytorch2.0.0 torchvision0.15.0. In this video, we will take you through the installation process of OpenCV on MacOS.OpenCV BeginnersSeries Course Website. Here are the set of steps to resolve this. Some links suggest for Brew and some virtual env, some say install xcode but all failed in my case. The reason for it not to be found is because brew installs the file in different locations. The problem arises due to the fact that cv2.so from python site-packages tries to link to a file which can not be found.
