python modules are not imported in VS Code

I have some problem with my Visual Code settings. Currently I work with Python, but ctrl+click or Go to Definiton works. Not even within the same class.

Under Problems I get a bunch of errors like Unable to import utils and so on for all my python files.

My settings.json looks like:

{
    "python.pythonPath": "~/.virtualenvs/sonyproject/bin/python",
    "python.linting.pylintEnabled": true,

    "python.autoComplete.extraPaths": [
        "/usr/wiss/myname/Code/sonyproject/SonyBody/python_body/**",
        "/usr/wiss/myname/Code/LocalLibs/PythonLibs",
        "${workspaceFolder}/src/**",
        "${workspaceFolder}/**",
        "/usr/wiss/myname/Code/newresearch2/HumanShapePose/DVOApproach/ProjectPoints/src/**",
        "/usr/wiss/myname/Code/newresearch2/HumanShapePose/DVOApproach/ProjectPoints/src/utils/**"
    ],
    "window.zoomLevel": 0,
    "python.analysis.memory.keepLibraryAst": true,
    "python.analysis.memory.keepLibraryLocalVariables": true
}
