How to Launch Jupyter Notebook in WSL Using PowerShell

Are you looking to streamline your workflow and run Jupyter Notebook in the Windows Subsystem for Linux (WSL)? If you've got Python packages installed in WSL and want to leverage them in your projects, you're not alone. Many users find themselves facing hurdles when trying to initiate Jupyter Notebook using PowerShell. This guide will guide you through the solution step-by-step, so you can get up and running easily.

Understanding the Problem

When using PowerShell to launch Jupyter Notebook in WSL, many users encounter the error message: bash: jupyter: command not found. This can be frustrating, especially when you can manually launch Jupyter Notebook from within WSL without any issues. Here are a couple of common problems that users face:

Command Not Found: When attempting to run jupyter notebook, the command isn’t recognized.

Terminal Behavior: Some attempts to launch Jupyter may result in a terminal that opens and closes instantly, providing no opportunity to diagnose the issue.

The Solution: Using PowerShell to Launch Jupyter Notebook

The root of the issue often lies in how bash loads its configuration. When you execute commands in WSL with the -c option, it does not load your ~/.bashrc file, which is where many initializations are defined. These initializations typically include setting up the environment for various tools like Jupyter Notebook.

Step-by-Step Guidance

To solve this issue, follow these steps:

Open PowerShell: Start by launching PowerShell on your Windows machine.

Run Bash with Interactive Mode: Instead of the previous command, use the following command:

Here’s the breakdown of this command:

wsl: This starts up your Windows Subsystem for Linux.

-e bash: This tells WSL to execute the bash shell.

-i: This option specifies that the bash session should be interactive. This means that your ~/.bashrc file will be loaded, allowing all necessary initializations for Jupyter Notebook to be available.

"jupyter notebook": This is the command you want to run once the interactive shell is loaded.

Press Enter: After typing the command correctly in PowerShell, press Enter to launch Jupyter Notebook.

Additional Considerations

Alternative Installations: While using Windows Jupyter with WSL kernels is an option, it’s more efficient to directly run Jupyter from within WSL if your packages are installed there.

Debugging: If you continue to encounter issues, consider checking your ~/.bashrc file to ensure all necessary path configurations for Python and Jupyter are correctly set up.

Conclusion

By following these steps, you should be able to smoothly launch Jupyter Notebook within WSL through PowerShell, leveraging all the Python packages you have installed. If you experience any further issues or have questions, feel free to share them in the comments. Happy coding!
