Join Barron Stone for an in-depth discussion in this video, Installing Python 3 and Tcl/Tk for Mac, part of Python GUI Development with Tkinter (2014). /Applications/Python 3.6/Install Certificates.command python3 -m nltk.downloader book That completed the installation successfully of nltk and nltk_ata for book examples Questions. Introduction offers a command shell for interactive computing as a web application. The tool can be used with several languages, including Python, Julia, R, Haskell, and Ruby. It is often used for working with data, statistical modeling, and machine learning. This tutorial will walk you through setting up Jupyter Notebook to run either locally or from an Ubuntu 16.04 server, as well as teach you how to connect to and use the notebook. Jupyter notebooks (or simply notebooks) are documents produced by the Jupyter Notebook app which contain both computer code and rich text elements (paragraph, equations, figures, links, etc.) which aid in presenting and sharing reproducible research. By the end of this guide, you will be able to run Python 3 code using Jupyter Notebook running on a local machine or remote server. Prerequisites To follow this tutorial, you will need a Python 3 programming environment, either • on your, or • on an. All the commands in this tutorial should be run as a non-root user. If root access is required for the command, it will be preceded by sudo. Explains how to add users and give them sudo access. Step 1 — Installing Jupyter Notebook In this section we will install Jupyter Notebook with pip. ![]() Activate the Python 3 programming environment you would like to install Jupyter Notebook into. In our example, we’ll install it into my_env, so we will ensure we’re in that environment’s directory and activate it like so: • cd ~/ environments •. My_env/bin/activate Next, we can ensure that pip is upgraded to the most recent version: • pip install --upgrade pip Now we can install Jupyter Notebook with the following command: • pip install jupyter At this point Jupyter Notebook is installed into the current programming environment. The next optional step is for those connecting a server installation of the web interface using SSH tunnelling. Step 2 (Optional) — Using SSH Tunneling to Connect to a Server Installation If you installed Jupyter Notebook on a server, in this section we will learn how to connect to the Jupyter Notebook web interface using SSH tunneling. Since Jupyter Notebook will run on a specific port on the server (such as:8888,:8889 etc.), SSH tunneling enables you to connect to the server’s port securely. The next two subsections describe how to create an SSH tunnel from 1) a Mac or Linux and 2) Windows. Please refer to the subsection for your local computer. SSH Tunneling with a Mac or Linux If you are using a Mac or Linux, the steps for creating an SSH tunnel are similar to the guide except there are additional parameters added in the ssh command. ![]() This subsection will outline the additional parameters needed in the ssh command to tunnel successfully. SSH tunneling can be done by running the following SSH command in a new local terminal window: • ssh -L 8888:localhost: 8888 your_server_username@ your_server_ip The ssh command opens an SSH connection, but -L specifies that the given port on the local (client) host is to be forwarded to the given host and port on the remote side (server). This means that whatever is running on the second port number (e.g. 8888) on the server will appear on the first port number (e.g. 8888) on your local computer. Optionally change port 8888 to one of your choosing to avoid using a port already in use by another process. Server_username is your username (e.g. Sammy) on the server which you created and your_server_ip is the IP address of your server. For example, for the username sammy and the server address 203.0.113.0, the command would be: • ssh -L 8888:localhost: 8888 sammy@ 203.0.113.0 If no error shows up after running the ssh -L command, you can move into your programming environment and run Jupyter Notebook: • jupyter notebook You’ll receive output with a URL. From a web browser on your local machine, open the Jupyter Notebook web interface with the URL that starts with Ensure that the token number is included, or enter the token number string when prompted at SSH Tunneling with Windows and Putty If you are using Windows, you can create an SSH tunnel using Putty as outlined in. First, enter the server URL or IP address as the hostname as shown: Next, click SSH on the bottom of the left pane to expand the menu, and then click Tunnels.
