In my case, this was due to the dynamic libraries of opencv trying to reach the wrong version of 'libm.so'. There are plenty, for Fedora 20, which is what I am using, you can find:Д®ven if you don't have Fedora, it might be useful to check all of the CMake variables they set, since this is made to reduce the compilation time, and avoid unnecessary modules that the Python module 'cv2' might not be able to use anyway).ДЄfter the compilation, I got an IMPORT_ERROR in Python when doing 'import cv2'. I would recommend you follow a step-by-step guide if you are not familiar with the compiling process. UnsatisfiableError: The following specifications were found to be in conflict: - opencv3 -> python 2.7 - python 3.6 Use conda info &. Install rosbag and sensor msgs: conda install -c conda-forge ros-rosbag ros-sensor-msgs Install opencv-python : pip install opencv-python Disbale ROS Opencv (this is a hack since ROS OpenCV supports Python 2.7, so we rename the cv2. In all of them, you'll need to specify the path to the anaconda installation, not the system-installed Python interpreter (CMake, the tool used to compile OpenCV might automatically find either, or even a mixture!). And you will need to change the variable that was pointed out before, but not just this variable (PYTHON_PACKAGES_PATH) but also all those referring to PYTHON paths (starting by PYTHON2_ or PYTHON3_), for instance: You will need to compile OpenCV for yourself (not daunting, I hope). Conda not able to solve environment for installing OpenCV on Ubuntu 20.04, regardless of whether it's on base environment or on a freshly created one. If conda is installed you should see somehting like the following.I've just gone through the whole process, therefore, I find the previously given answer a bit too vague (sorry, no offence).This also means conda can install non-Python libraries and tools you may need (e.g. Enter conda -V into the terminal command line and press enter. The first difference is that conda is cross-language and it can install Python, while pip is installed for a particular Python on your system and installs other packages to that same Python install only.Check conda is installed and in your PATH Anaconda Python distribution installed and accessibleДЎ.

If you have a vanilla Python installation or other Python distribution see virtualenv Outline The conda command is the preferred interface for managing intstallations and virtual environments with the Anaconda Python distribution.

If Ubuntu 16.04 is installed in WSL sudo do-release-upgrade will upgrade it to 18.04. Upgrade your OS to 18.04 if you are using Ubuntu 14.04 or Ubuntu 16.04.

Open the terminal and type: sudo apt install python3-opencv. Virtual environmets make it easy to cleanly separate different projects and avoid problems with different dependencies and version requiremetns across components. python3-opencv can be installed from the Universe repository in Ubuntu 17.10 and later.

How to set up a virtual environments using conda for the Anaconda Python distributionДЄ virtual environment is a named, isolated, working copy of Python that that maintains its own files, directories, and paths so that you can work with specific versions of libraries or Python itself without affecting other Python projects. This should install OpenCV in your Anaconda. Create virtual environments for python with conda If the version of python install in your Anaconda is 2.7, the command above should install OpenCV 3.1, but if the version of your python is 3.5, then you should change 'opencv' in the last line to 'opencv3'.
