Optional flags: (there are a lot of flags, see this blog post for some useful ones) -DINSTALL_C_EXAMPLES=ONĮnsure cmake finds your python version by checking its output for the following: - Python 2: I use the following cmake flags: cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_EXTRA_MODULES_PATH=././opencv_contrib/modules. If you mess up, just delete build folder and start over from here.

Ubuntu conda install opencv python 2.7 install#

(Git branch to 3.4 to install that version.) 1.1 Make build folder The installation will include contrib modules. Sudo apt install libjasper1 libjasper-dev How to install jasper: sudo add-apt-repository "deb xenial-security main" sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev Requirements sudo apt-get install build-essential I put the answer here so it has wider visibility. The following, tested on Ubuntu 18.04, installs OpenCV 4.1.0-dev and does not use python virtual environment. Step 3 Follow the remaining steps as mentioned in the link till sudo make install Note: Don't forget to change your python version and path in PYTHON_DEFAULT_EXECUTABLE. Instead of cmake mentioned on the page, use this, cmake -D CMAKE_BUILD_TYPE=Release -D BUILD_NEW_PYTHON_SUPPORT=ON -D BUILD_opencv_python3=ON -D HAVE_opencv_python3=ON -D PYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3.4. You can find that out by using command whereis python3.4 (or, your version). Step 2 For installing opencv in specific version of python (ubuntu), you have to set the default (PYTHON_DEFAULT_EXECUTABLE) with the path to where your python is installed. I did sudo apt-get install python3-dev python3-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev That optional one too.!! And don't forget to change the python version for which you are installing. Note: Install all the 3 packages mentioned at start. Step 1 Follow all the steps as mentioned on openCv installation part till cmake. I will share the steps I followed so as to help others on it. I wanted opencv to be installed for python 3.4 but every time it was getting installed on 2.7 version. Installing opencv on python3.4 version has been quite a task. I am currently working with Google VM (ubuntu 14.04).

After the process is finished, run make and then sudo make install.

Then rename the folder opencv to opencv-3Ĭreate a build directory, move to it and run: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local.

Create a temporary directory, move into it and run: git clone.

To solve this problem, we’ll copy the file from the current location to the expected location: sudo cp /usr/include/x86_64-linux-gnu/python3.5m/pyconfig.h /usr/include/python3.5m/ The first part of the output is the expected location & the second part shows the current location of the config file.

Copy the dev files: python3.5-config -includes The output should be similar to: -I/usr/include/python3.5m -I/usr/include/x86_64-linux-gnu/python3.5m.

Install the developer packages for Python3.5: sudo apt-get install python3.5-dev.

Ubuntu conda install opencv python 2.7 update#

Update the repository: sudo apt-get updateĭownload the required packages to compile OpenCV: sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev.

Here are the instructions I tested successfully and mentioned in the link above:

Ubuntu conda install opencv python 2.7 download#

At the latest version it's fixed, try:īut I didn't download dev python and OpenCV, I took directly from github: I have OpenCV version 3.1 on Ubuntu 16.04 LTS to work with Python 3.5.1.
