CMAKE_BUILD_TYPE=RELEASE : We are telling cmake that we are building a “release” version of OpenCV.

Let’s take a moment to understand what these flags mean exactly: $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/path/to/opencv-3.0.0/build -D PYTHON2_LIBRARY=/usr/local/Cellar/python/2.7.9/Frameworks/amework/Versions/2.7/bin -D PYTHON2_INCLUDE_DIR=/usr/local/Frameworks/amework/Headers -D PYTHON2_PACKAGES_PATH=/usr/local/lib/python2.7/site-packages -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=/path/to/opencv_contrib-3.0.0/modules.

Run the following commands from you terminal: $ cd /path/to/opencv-3.0.0/

Bear in mind that some of them are not free for commercial use, but it is great tool to learn new algorithms. It is basically a repository that contains state of the art algorithms. If you see “/usr/local/bin/python” printed on your terminal, you can proceed.ĭownload OpenCV 3.0.0: You can download it from here.ĭownload “opencv_contrib”: As discussed earlier, we can use the latest computer vision algorithms from “opencv_contrib”. Run the following command from your terminal: $ which python Let’s confirm that you are using brewed Python. Run the following command to do it: $ source ~/.profile

We need to reload the file to update the environment variables. Open up your ~/.profile file and add the following line: export PATH=/usr/local/bin:$PATH

Now that Homebrew is installed, let’s update it and install Python: $ brew update If you don’t have Homebrew, you can install it using the following command: $ ruby - e "$(curl -fsSL Instead of using system Python, we need to use brewed Python (this is basically Python installed using Homebrew). Install Python using Homebrew: This is an important step! Homebrew is a package manager for OS X that makes our lives easier in many different ways.

It’s a dmg file, so you can just download it and run the installer. If you don’t, you can download it from here.

Let’s see how to install OpenCV 3 with Python support on Mac OS X.ĬMake: Make sure you have cmake. Since OpenCV is available on almost all the popular platforms, this version looks very promising. They have greatly improved Python support in this release as well. One of the main additions of OpenCV 3 is “opencv_contrib” which contains a lot of cutting edge algorithms for feature descriptors, text detection, object tracking, shape matching, and so on. OpenCV has been around for a while now and they add something new and interesting with every new release. I tried with a conda install and it worked fine.OpenCV is the world’s most popular computer vision library and it’s used extensively by researchers and developers around the world. ModuleNotFoundError: No module named 'Numeric'Įvidently Python is still screwed up. ModuleNotFoundError: No module named 'numpy'ĭuring handling of the above exception, another exception occurred:įile "/usr/local/bin/gdal_merge.py", line 611, in įile "/usr/local/bin/gdal_merge.py", line 596, in mainįile "/usr/local/bin/gdal_merge.py", line 343, in copy_intoįile "/usr/local/bin/gdal_merge.py", line 124, in raster_copyįile "/usr/local/bin/gdal_merge.py", line 174, in raster_copy_with_mask Results in 0Traceback (most recent call last):įile "/usr/local/bin/gdal_merge.py", line 172, in raster_copy_with_mask First, I install according to the above comment. Unfortunately the GeoTIFFs I'm using are too large to share, but I'm pretty sure the below error could be reproduced with any two images.

Type "help", "copyright", "credits" or "license" for more information.Ĭorrect, I'm using GDAL for raster processing (satellite images, in my case). Kelvins-MacBook-Pro-899:~ kelvin$ python3.6 For instance, 2.7 and 3.7 both give a "ModuleNotFoundError: No module named 'osgeo'" error, but 3.6 works. I have found that sometimes only one version of Python can correctly import gdal without any dramas. Python setup.py build_ext -gdal-config /usr/local/Cellar/gdal/HEAD-41888_2/bin/gdal-configĭo an 'ls /usr/local/Cellar/gdal/' if you need to get the revision number. Python setup.py build_ext -I/Library/Frameworks/amework/Versions/2.3/Headers -L/Library/Frameworks/amework/Versions/2.3/unix/lib -gdal-config /Library/Frameworks/amework/Versions/2.3/unix/bin/gdal-configĪlternatively, install GDAL via brew, then do similar to the above. Via GDAL Framework / QGISįirst, you can install the GDAL Framework via QGIS (or get it directly), and then do. I've found two ways to install the GDAL Python bindings on Mac.
