Inline completion provider using transformers.js
for JupyterLab
This extension is aimed for developers of JupyterLab extensions (and advanced JupyterLab users) to explore the integration of the inline completions API added in JupyterLab 4.1.
All models linked from this demonstration run exclusively in your browser, and are:
These models are not vetted for accuracy nor propriety and should not be deployed without further validation.
SharedArrayBuffer
dom.workers.modules.enabled
in Firefox)dom.webgpu.enabled
in Firefox)jupyter-server
to enable additional headers (jupyverse
and jupyterlite
not tested yet)When this extension is enabled, the server will return additional headers, which will prevent fetching external resources, for example the extension logos from GitHub will no longer load in the extension panel.
The additional headers are used to enable synchronous communication with WebWorker via SharedArrayBuffer
:
Cross-Origin-Opener-Policy: same-origin,
Cross-Origin-Embedder-Policy: require-corp
To install the extension, execute:
pip install -U 'jupyterlab>=4.1.0' jupyterlab-transformers-completer
To remove the extension, execute:
pip uninstall jupyterlab-transformers-completer
Note: You will need NodeJS to build the extension package.
The jlpm
command is JupyterLab's pinned version of
yarn that is installed with JupyterLab. You may use
yarn
or npm
in lieu of jlpm
below.
# Clone the repo to your local environment
# Change directory to the jupyterlab-transformers-completer directory
# Install package in development mode
pip install -e "."
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm build
You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.
# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm watch
# Run JupyterLab in another terminal
jupyter lab
With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).
By default, the jlpm build
command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:
jupyter lab build --minimize=False
pip uninstall jupyterlab-transformers-completer
In development mode, you will also need to remove the symlink created by jupyter labextension develop
command. To find its location, you can run jupyter labextension list
to figure out where the labextensions
folder is located. Then you can remove the symlink named @jupyterlab/transformers-completer
within that folder.
