@ducha-aiki can you disable https://travis-ci.com/arraiyopensource/kornia/jobs/216810007#L1510 ?
add pytest.mark.skip('some mesage')
we'll have to take a serious look at the jitted operator after the deadline

[ducha-aiki]

This would requre editing all the tests. Is there a way to turn off all jits without it?
