Running Jupyter Notebook on Windows

Jupyter Notebook is a popular web-based interactive environment for working with Python and other programming languages. It provides an intuitive interface for writing and executing code, visualizing data, and collaborating with others. In this tutorial, we will cover the steps to install and run Jupyter Notebook on Windows.

Installing Jupyter Notebook

To install Jupyter Notebook, you need to have Python installed on your system. You can download the latest version of Python from the official Python website. Once you have Python installed, open a command prompt or terminal and type the following command:

pip install jupyter

This will install Jupyter Notebook and its dependencies.

Running Jupyter Notebook

After installation, you can run Jupyter Notebook using the following command:

jupyter notebook

However, if you encounter an error message saying that 'jupyter' is not recognized as an internal or external command, operable program or batch file, it means that the Jupyter executable is not in your system’s PATH.

Resolving the PATH Issue

To resolve this issue, you can use the following methods:

1. Run Jupyter Notebook using Python: You can run Jupyter Notebook using the Python interpreter by typing:

python -m notebook

This will launch Jupyter Notebook without requiring the jupyter command to be in your system’s PATH.

2. Add the Jupyter executable to the PATH: You can add the Jupyter executable to your system’s PATH manually. The location of the Jupyter executable varies depending on your Python installation and version. Typically, it is located in the Scripts directory of your Python installation. For example:

C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts\jupyter.exe

You can add this directory to your system’s PATH using the following PowerShell command:

[Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts", [EnvironmentVariableTarget]::User)

Replace <username> with your actual username.

Launching Jupyter Notebook

Once you have resolved the PATH issue, you can launch Jupyter Notebook by typing:

jupyter notebook

This will open a web browser window with the Jupyter Notebook interface. You can create new notebooks, upload existing ones, and start working with Python code.

Tips and Variations

• If you are using Python 3.x, you can use py -m notebook or python3 -m notebook to launch Jupyter Notebook.
• If you are using JupyterLab, you can launch it using jupyter lab or py -m jupyterlab.
• You can also install Jupyter Notebook using a package manager like Anaconda or Miniconda.

By following these steps and tips, you should be able to successfully install and run Jupyter Notebook on Windows.
