Jupyter kernels are an essential component of the Jupyter ecosystem, allowing you to run different programming languages within the Jupyter Notebook interface. This document provides an overview of Jupyter kernels and how to manage them.
What is a Jupyter Kernel?
A Jupyter kernel is a piece of software that allows Jupyter to execute code in different programming languages. Each kernel is responsible for running a specific language, such as Python, R, or Julia.
Available Kernels
Here are some of the commonly used Jupyter kernels:
- Python: The default kernel for Jupyter, designed to run Python code.
- R: A kernel for running R code within Jupyter.
- Julia: A kernel for running Julia code within Jupyter.
- MATLAB: A kernel for running MATLAB code within Jupyter.
Managing Kernels
To manage your Jupyter kernels, you can use the following commands:
- List available kernels:
jupyter kernelspec list - Install a new kernel:
jupyter kernelspec install /path/to/kernel - Uninstall a kernel:
jupyter kernelspec uninstall <kernel_name>
