Recently, we were working on a python 3 project that was using opencv. When we used condadefaults repository to install opencv it installed a 3.X.Y version which would produce the following error on PyCharm on Ubuntu 20.04 LTS:
pycharm cv2.error: OpenCV(3.4.2) highgui/src/window.cpp:710: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvStartWindowThread'
Following the instructions above, we installed the missing packages using sudo apt-get install libgtk2.0-dev pkg-config; with no change on the results. To fix the issue, we completely removed opencv from the stables repository and we installed version 4.5.1 from the conda-forge repository as follows:
Easy Setup - Slow Execution by using the CPUs only Getting CUDA support in OpenCV for Python can be tricky as you will need to make several changes to your PC. On many occasions, it can fail if you are not comfortable troubleshooting the procedure. For this reason, we are…

We decided to revisit this post (https://bytefreaks.net/applications/neural-style-tf-another-open-source-alternative-to-prisma-for-advanced-users) in 2021 and provide the installation manual for Ubuntu 20.04LTS. Setup Conda / Anaconda First of all, we installed and activated anaconda on an Ubuntu 20.04LTS desktop. To do so, we installed the following dependencies from the repositories: sudo apt-get install libgl1-mesa-glx libegl1-mesa…
