Anaconda is great for easily establishing a python ecosystem in a windows machine, but for linux it usually brings more problems than solutions.Īnd for the question why installing gcc-gfortran-5.3.86_64 does not solve the problem: This package provides libgfortran.so.3, whereas your libopenblas needs libgfortran.so.1 (an older version). You could simply use the python provided by your distro and install additional python modules with either your distro's package manager or (if you want more recent package versions or don't have root access) with pip install -user.

In my opinion anaconda is not very useful in a unixoid environment, it even makes things more difficult since you already have a working python environment and add another, which almost inevitably to problems. cv::imread () is from the imgcodecs module, so you need to add another lib to your cmdline: g++ main. I used to have OpenCV3 from the Arch Linux pckage manager (pacman) and it worked fine but when I removed it and install OpenCV 3.4.

Ah, did you install openblas somehow through Anaconda? That would explain a lot.
