Installing JupyterLabs

For a better experience, you should install Jupyter Lab inside a virtual environment.

After the installation is complete, create a new environment:

python3 -m venv jlab

Note that you can replace the jlab with any name of your choice.

Now activate the environment:

. jlab/bin/activate

Activating a virtual environment

Now install Jupyter Lab in Ubuntu:

pip install jupyterlab

Once the installation is complete, you can start Jupyter lab by running:

jupyter lab

Jupyter Labs runs locally on port 8888: localhost:8888

Installing Javascript Kernel

Inside the activated virtual environment, install the javascript kernel by running:

npm install -g ijavascript

To activate the kernel, run:

ijsinstall

Re-start Jupyter lab:

jupyter lab
