Hi,
TabNine changed the path from "x86_64-unknown-linux-gnu" to "x86_64-unknown-linux-musl"

so coc does not pick up the latest models and just downloads them..

[coc.nvim] error: Uncaught exception: Error: spawn /Users/admin/.config/coc/extensions/coc-tabnine-data/binaries/2.5.1/x86_64-apple-darwin/TabNine EACCES
    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19)
    at onErrorNT (internal/child_process.js:415:16)
    at process._tickCallback (internal/process/next_tick.js:63:19)
Press ENTER or type command to continue

I have TabNine installed local, In my Neovim, it reports this code:
What can i do for it?

The current TabNine version 2.1.20 consumes drastic amounts of CPU and RAM. When typing, it is always near 100% CPU and takes up about 1.5 GB of ram in a single file (As I just began using TabNine I am not sure how much usage is normal, but this seems to be too much)

This Issue is not new and seemed to occur repeatedly throughout the versions as seen in this thread.

Is it be possible to specify which version of TabNine could be used?

the option tabnine.binary seems that can only use absolute path.

Can it support environment variable name( such as $HOME) and ~, just like plugin coc-snippets

thx

Hi, completionItemKindLabels for TabNine suggestions are not visible except for kind "snippet". I am using this on macOS ARM64 with neovim nightly (NVIM v0.5.0-dev+nightly-120-g1186f7dd9).

Not really a bug, but it took me a while to figure out what's wrong so it may be useful to someone else. It installs absolutely & fine the settings work in CocConfig, yet no commands exist nor does the autocompletion work.

Here are the error messages

I installed coc-tabnine yesterday and noticed that, while typing : still triggers results for coc-emoji, emoji results are removed from the list upon typing any other characters. Disabling coc-tabnine and restarting nvim seems to resolve the issue.

I'm not sure if this is an issue with coc-tabnine, an issue with coc-emoji, or if it's simply a configuration probably on my end. I've tried setting coc.source.emoji.priority to various values (0 and 200) to see if it made a difference and it did not.

currently only have disable_filetypes, but I want to use tabnine only in some specified filetype.

When using tabnine for completion, the completion function is weaker in coc than in deoplete, so it's very difficult to use it.
I checked the Logs on the Config screen, but it was very difficult to use and I couldn't see the logs properly.

Attached is an image of the comparison below.
The left one is deoplete and the right one is coc.

Hi, folks

Amir from tabnine here.

We have recently released support the new for Apple M1 processors.
This requires some changes on the plugin side too.

We've updated the how to write a plugin document.
We also implemented it in various other plugins, so you can check it out to get inspiration :-)

vscode
sublime
intellij
vim

Note that supporting m1 when the editor is run nativelyon arm is usually pretty straight forward. However, supporting a case where the editor is running on the Rosetta translator is a little more complex (see this).

magic_strings' link has been invalid, and the new link is special commands: https://www.tabnine.com/faq#special_commands

I set "suggest. noselect": false, but coc-tabning always automatically selects the first item!
Is there anything wrong with my settings? Thank you

I want to use tab to cycle suggestions and to complete, so I copypasted coc.nvim's sample code into my init.vim. Relevant section:

" Use tab for trigger completion with characters ahead and navigate.
" Use command ':verbose imap <tab>' to make sure tab is not mapped by other plugin.
inoremap <silent><expr> <TAB>
      \ pumvisible() ? "\<C-n>" :
      \ <SID>check_back_space() ? "\<TAB>" :
      \ coc#refresh()
inoremap <expr><S-TAB> pumvisible() ? "\<C-p>" : "\<C-h>"

function! s:check_back_space() abort
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~# '\s'
endfunction

Pressing tab completes all the [A] suggestions, but not the [TN] ones.

First off -- thank you for this plugin!

Would it be possible to add a config setting to change priority? I'm trying to make https://github.com/neoclide/coc-tsserver have higher priority to Tabnine.

Cheers!

Hello,

I don't want this extension to manage downloading the tabnine executable. I think it's a nice service to offer, but I would prefer to download my own executable, put it in a common folder and use it for multiple editors. That way I only need to update one file to update tabnine.

Background:
Currently, https://update.tabnine.com/version returns 2.0.4, so coc-tabnine downloads it. But the version is not stable, and segfaults on my system. I don't know why unstable version is mentioned in that file, but even the tabnine auto-update does not update from 2.0.2 to 2.0.4. So it seems like a bad idea to use that URL.

(I fixed the problem by manually downloading version 2.0.2, and placing it in the coc-tabnine-data directory, so I don't need assistance to get anything running).

Hello,

I'm running NVIM v0.4.0-1155-gc62690ccc on MacOS Mojave. I'm using the latest version of coc with coc-tabline, and encountering a few issues.

After I installed the extension, and open source code in nvim I got an EACCESS error regarding the TabNine binary. It did not have executable permissions after installation. (chmod +x)

Typing TabNine does not trigger completion.

I've issued :CocCommand tabnine.openConfig but nothing happens.

I checked :messages, and I have the following several times.
source tabnine timeout after 2000ms

The Readme mentions setting "ignore_all_lsp": true in the tabnine configuration. Would you mind clarifying this? Does it go in CocConfig?

Thanks

coc.nvim would download TabNine instead of bundled with this extension.

The download process would start on vim start when necessary.

Hello I have this problem ongoing everytime I open vim , first timeout then this.

Is there something I didn't instsll ?

Thanks

As soon as I open neovim and start typing something, I get this error:
.

vim version: NVIM v0.5.0-7e0e0782a
node version: v15.3.0
coc.nvim version: 0.0.79-9eb7e5b2ae
coc-tabnine version: 1.2.3

So, I've got coc-tabnine installed via vim-plug:

Plug 'neoclide/coc-tabnine', {'do': 'yarn install --frozen-lockfile'}

Unfortunately, attempting to actually run yarn install --frozen-lockfile yields an infinite loop, where I'm repeatedly asked by npx webpack whether I want to install webpack-cli:

https://asciinema.org/a/qSblKmGWlFvBNAHBxzeXToWzG

Not sure what's up with this, hope this report is helpful. Perhaps I am doing something wrong!

Where and how to run "tabnine.openConfig" command?

I bought a license for myself, however I can't activate it with my coc-tabnine.
Error message:

when I type tabnine.openConfig

Hi,

The tabnine binary for linux working good with freebsd. So, Could you please add support to freebsd.

TabNine updates quite frequently, and this could leave lots of old binaries in coc-tabnine-data.
I suggest cleaning old TabNine binaries after downloading a new version.

When trying to perform the version test by typing in TabNine::version I get TabNine to complete, but not version and the version info is not displayed.

Moreover, my config shows version 1.0.10, which is outdated.

these ones: https://tabnine.com/faq#magic_strings

Hey 👋,

I'm getting coc-tabnine to install and it downloads the 2.0.4 binary. The autocomplete works fine but I'm unable to properly configure it, license key / beta access etc. CocCommand tabnine.openConfig just gives me an empty JSON file and TabNine::config does nothing.

I'm very confused on how I'm supposed to configure TabNine / coc-tabnine. All help appreciated! ❤️

hi.

I install coc.nvim and coc-tabnine and execute CocCommand tabnine.openConfig.
But cannot open TabNine's config(nothing response).

I tried Tabnine with deoplete.
It can use Tabnine.

Please teach me how to setting.

Deep TabNine

This plugin only supports version 1.x, even when I attempt to force an update.

If you need any help with this, perhaps I can be useful here - let me know.

TabNine has updated there download script last year November dl_binaries.sh

Mainly updated the url to check version and download.

version="$(curl -sS https://update.tabnine.com/bundles/version)"

# https://github.com/codota/TabNine/blob/c6c2ee071a12461bb45e6367af5b4d4e71f25e5b/dl_binaries.sh#L6

    curl -sS https://update.tabnine.com/bundles/$path/TabNine.zip > binaries/$path/TabNine.zip

# https://github.com/codota/TabNine/blob/c6c2ee071a12461bb45e6367af5b4d4e71f25e5b/dl_binaries.sh#L21

https://update.tabnine.com/bundles/version and https://update.tabnine.com/version will get different versions. The version applicable to M1 chip must use the updated version. The present version will get a 403 error.

The updated version also needs to modify the download path, which needs to be decompressed after downloading. I tried to adjust the url and add extract:'unzip' to the download function, but found that the main TabNine binary will be deleted after the program runs. There may be path-related issues that require additional adjustments.

I have installed tabnine use command "CocInstall".
And i got this when using "CocCommand tabnine.openConfig".

[coc.nvim] Error on install tabnine: Error: Invalid response from https://registry.npmjs.org/tabnine: 404

Network Check

Allowing CoC to communicate semantic completions back to TabNine from other language servers would allow TabNine to learn better and provide better completions. For this to work, CoC would have to be able to act as a language server proxy of sorts.

The following error happens just after the coc-tabnine installation.

[coc.nvim] Installed extension: coc-tabnine
[coc.nvim] Error on active extension coc-tabnine: TypeError: coc_nvim_1.fetch is not a function

Hi chemzqm:

Is there a way to add my license?
My own project size is larger than 400KB. Is there a way to add the purchased license?

Best

Hi,

I tried to use the ":CocInstall coc-tabnine" command to install this plugin and met following error

at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)

Seems like network issue. As for the network status, CocInstall works fine for other plugins like ":CocInstall coc-word" and My vim is also able to install tabnine-vim[1].

Do you have any suggestions?

[1] tabnine-vim: https://github.com/zxqfl/tabnine-vim

Sometimes tabnine gives the completion of a whole sentence, but coc only completes the first word of it.

Hi there. I'm using coc with neovim on my Linux machine for c++ development.

I'm a pro tabnine subscriber and would like to use the local model. But this doesn't seem to be working.

Is there any way I can get logging info from the TabNine engine?

Note: coc-tabnine works on my mac with the same config, etc.

Hi!

What happens

When I try to install coc-tabnine on my pi 4 (aarch64) the following error occurs:

[coc.nvim] Download error Invalid response from https://update.tabnine.com/bundles/3.5.35/aarch64-unknown-linux-musl/TabNine.zip: 403

According to #35 the reason coc-tabnine can't be previewed and completed using the same key is because the suggestions are for snippets.

It would be better if they weren't snippets.
