Issue Details: After upgrade to Fedora 35, opening vim results in below error in status line:

YouCompleteMe unavailable: module 'collections' has no attribute 'Mapping'

I suspect it is because Fedora 35 upgrades Python from 3.9 to 3.10 I can't seem to get TabNine::config running in vim.

did you try our new fork? https://github.com/tabnine/YouCompleteMe

[WiSaGaN]

No. Can you elaborate why that is relavent to this issue?

[bilucodota]

The new fork is updated more frequently and thus expected to work better on newer installations.

No. Can you elaborate why that is relavent to this issue?

have you solved this problem?

[bilucodota]

@WiSaGaN @luoleicn we've added python3 support on this branch: https://github.com/codota/tabnine-vim/tree/python3

[WiSaGaN]

Thanks @bilucodota . This now works for me. Please feel free to close this when you see fit.

[bilucodota]

Keep us posted!

[luoleicn]

@bilucodota Thank you, but python3 branch doesnot work either, still "YouCompleteMe unavailable: module 'collections' has no attribute 'Mapping'"

[luoleicn]

and my evn is Python 3.7.3, VIM - Vi IMproved 8.2, macOS 12.1

[bilucodota]

Hi @luoleicn can you share the status of git show as well as the output of :messages ? One again - I would definitely recommend that you switch to our latest YCM fork https://github.com/tabnine/YouCompleteMe

[luoleicn]

@bilucodota thanks, I moved to https://github.com/tabnine/YouCompleteMe, but still not working:(, :message said:

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). Unexpected exit code -6. Type ':YcmToggleLogs ycmd_60335_stderr_3zwquq7b.log' to check th

I check ycmd_60335_stderr_3zwquq7b.log No global extra conf, not calling method YcmCorePreload

[bilucodota]

did you follow the installation instructions? https://github.com/tabnine/YouCompleteMe#installation

[luoleicn]

@bilucodota Thanks again, I change my default python from miniconda3 to homebrew, it works for me now, although i dont know why

[bilucodota]

great!

Hi @bilucodota , I just ran into the same problem, apparently after my Manjaro (arch) updated python. python: 3.10.1 vim: 8.2.4106

I'm not using pathogen, vundle or some such thing but the built-in native package loading of vim 8.

As recommended here I installed https://github.com/tabnine/YouCompleteMe (in ~/.vim/pack/schrotie/start/YouCompleteMe and did python3 install.py --all there) successfully.

I also switched ~/.vim/pack/schrotie/start/tabnine-vim to the python3 branch. I tried calling the install script there. install.sh says it's deprecated and complains that urllib3 is missing (which is installed). python3 install.py fails with:

Traceback (most recent call last):
  File "/home/schrotie/.vim/pack/schrotie/start/tabnine-vim/third_party/ycmd/build.py", line 50, in <module>
    import requests
  File "/home/schrotie/.vim/pack/schrotie/start/tabnine-vim/third_party/ycmd/third_party/requests/requests/__init__.py", line 134, in <module>
    from . import packages
ImportError: bad magic number in 'requests.packages': b'\x03\xf3\r\n'

When I then start vim I get a ton of errors. However, I'm not sure if it prints all problems ... there's quite some traces. Some are:

AttributeError: type object 'BaseRequest' has no attribute 'session'. Did you mean: 'Session'?
ImportError: bad magic number in 'requests.packages': [...]
E858: Eval did not return a valid python object

Do you have any suggestions?

[schrotie]

The issue was solved for me by bilucodata. See issue 107.
