Sorry but this is a known limitation. We have a hack that lets us find the themes when using VS code in the local situation, but it doesn't work in the remote case. So we only provide light/dark in remote situations.

[neolyo]

did this feature added into the up to date version? I am thinking about swap to Jupyter Lab..

[rchiodo]

This is still a limitation. We are waiting on VS code to give us access to themes from a remote extension.

@rchiodo Would it be possible to have the theme as a setting in the python extension. I know it seems kind of silly to have to set the same theme twice, but it would get around the unexpected visual mismatch :)

[rchiodo]

Having the setting doesn't solve the root cause of the problem. We know what theme is picked, we just can't find the theme json data.

In the %USERPROFILE%\.vscode\extensions (on windows) is where theme extensions are installed. In the remote SSH case, our extension is not installed there, but on the remote machine. We need access to this folder in order to find the theme json contents. There's is currently no way for an extension to read this directory.

@rchiodo Thanks! I tried copying the extension data from %USERPROFILE%\.vscode\extensions to the ~/.vscode/extensions on the remote host. For the first 3 seconds everything was fine, but then it switched to the default light theme.

Would it be possible to also install the theme on the remote machine?

[rchiodo]

Yes that might work. We look next to the extension for the theme, so if the extension is installed remotely, it should find the theme if you install it remotely.

However I believe there are UI vs Remote extensions. The theme may not end up on the remote machine even if you install it there.

I installed a secondary theme on my local machine, copied its folder to the remote host, and deleted the first copy of the theme extension from my end. This leaves the extension theme on the remote host only, with my main theme installed locally.

Every time I go onto a remote server with ssh I'll have to switch to the other theme. The same theme can't be used since the local copy would override the remote copy automatically :\

[yeoldelloyd]

I can confirm this bug with the Remote - WSL extension, too. Copying the theme extensions into ~/.vscode_server/extensions does not work. Is there maybe another way to hack this?

[ajasja]

For anybody coming here through Google: There is a beautiful new themed native notebook interface that works with SSH remote! It's in the latest insiders VS Code (at least 1.49.0) and insiders python (v2020.9.104154-dev). Right click on a notebook and select "Open in preview Notebook Editor"

If it is still a limitation, would it be possible to provide more themes on the remote machine without installation? (eg. One Dark Pro) The default dark and light themes are really awful.

[zombba]

@yyNoBug you can use vscode insider or code-server . They provide many themes

@ajasja Hello, but I can't find the variable viewer in the Insight version. Do you know where to view the variable? "show variables active in jupyter kernel"

[IanMatthewHuff]

@xlilium It's sadly not there yet (I'm currently working on it :)). There are some features of the preview editor that are not fully matched up with the old webview based editor. Our short-term goal is to fill in these missing areas in the next few releases before moving this new notebook interface out of preview.
