2022Jan22-Enabling_jupyter_contrib_nbextensions_in_Sagemaker_Notebook

install_nbextensions_sagemaker.sh

'
This is a quick shortcut to enable jupyter_contrib_nbextensions in AWS SageMaker Notebook instance.

The correct way is to have the installation script as part of the instance Lifecycle Config.
Apparently you can do without, but as with virtual environments in AWS Sagemaker, you lose it if you kill the instance.

# Check whether vanilla nbextension is there or not
jupyter nbextension list

# Install jupyter_contrib_nbextensions. Note that you can enable all extensions in the package after these 2 lines.
pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install

# Enable nbextensions through terminal/use this bash script as-is if these are the packages you want
jupyter nbextension enable codefolding/main
jupyter nbextension enable codefolding/edit
jupyter nbextension enable collapsible_headings/main
jupyter nbextension enable execute_time/ExecuteTime
jupyter nbextension enable toc2/main

# Open or refresh a Jupyter Notebook. The extensions should already be enabled.
