Python-mode: PymodeLint sometimes doesn't work on save

[Ins1ne]

When i begin work - lint works well, but after some time lint just silently stops show errors even if they exist. Manually run :PymodeLint will show errors, but next save remove and don't show error window again. I also changed settings for syntastic to improve work with python-mode as described in their docs https://github.com/scrooloose/syntastic/blob/8e0f22ea414b241c57629561728de0900bb5870d/doc/syntastic.txt#L595:

let g:syntastic_filetype_map = {'mode': 'active', 'passive_filetypes': ['python']}

Same here, I have no idea why. The only "fix" I found is to restart vim...

[uralbash]

Same problem, I solved it like this:

au BufWriteCmd *.py write || :PymodeLint

[sonnyhu]

+1 same problem.

Please, you are commenting in a very old issue (about 3 years old), python-mode has changed a lot since then and there is a high probability that comments from this issue won't be helpful.

If you need, open a new issue with troubleshooting information so we can try to help you.
