Amazon CodeWhisperer (AI coding companion) is now available as an extension for JupyterLab. If you outline the coding task as a comment, this generative AI extension will auto-suggest single-line, multiline or full-function code right within the JupyterLab.  

Here's a guide on how to set up the CodeWhisperer extension with JupyterLab.

If you haven't installed JupyterLab yet, please refer to the article below.

Install JupyterLab or Jupyter Notebook in Windows Subsystem for Linux (WSL2)
Web-based interactive development environment JupyterLab (next generation of Jupyter Notebook ) is very popular in the field of data science and machine learning. Windows Subsystem for Linux (WSL2) is well known for super fast boot time, less resource consumption and seamless integration of Linux gu…

Launch JupyterLab

Launch JupyterLab jupyter-lab. By default, the Notebook server will be launched at http://localhost:8888/. I have launched JupyterLab on WSL (Windows Subsystem for Linux). So, I have used --no-browser flag and will access remotely from the host Windows machine using the URL with a token (e.g. http://localhost:8888/lab?token=e5743ec65c95a6f474ccdb4dbfff2882edd513ee8a31cead).

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.

https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html

Please note that updating to Notebook 7 might break some of your extensions.
