HowTo: Add Python 3 kernel to Jupyter Notebook

TWSC Interactive Container provides Jupyter Notebook by default. It is a web-based integrated development environment to write scripts, display output, visualize data... and many other functions. In addition, it can install multiple computing kernels of programming languages according to needs.

In some of TWSC container images (such as caffe-19.08-py2:latest), the Jupyter Notebook only supports Python 2 kernel (as shown in the figure below). We will show you how to add Python 3 Kernel to create a convenient computing environment!

Step 1. Connect to your Interactive Container​

Please refer to Connect to a container to connect to your Interactive Container.

Step 2. Install Python 3 Kernel​

Switch to the root user and install Python 3 kernel: 

sudo su 
apt-get update     
apt-get install python3-pip
python3 -m pip install ipykernel  
python3 -m ipykernel install

Step 3. Make sure that the installation is complete​

Refresh the Jupyter Notebook page, click New in the upper right corner to make sure that Python 2 and Python 3 are available. We're done!
