Pylint being naughty



I have linter-pylint and linter-flake8 installed.
pylint throws me some stuffs about pyQt5 so I ve found a solution online:

create a .pylintrc file at the root of my project and paste the following content inside:


Then I restart Atom, it works BUT it shows me MORE pylint warnings…
I stop my machine, next day, start my machine, open atom and pylint doesn’t show up anymore (same file) …

Why is pylint doing this ? Am I doing something wrong ?
