Jupyter Tips & Tricks

Show available kernels:

Install new custom kernel (such as PySpark):

• Reference: https://ipython.readthedocs.io/en/latest/install/kernel_install.html

1. Install dummy kernel in home directory:

• ipython kernel install --prefix ~/my_custom_jupyter_kernels

2. Edit name of ~/my_custom_jupyter_kernels/share/jupyter/kernels/python3 folder as desired.
3. Edit ~/my_custom_jupyter_kernels/share/jupyter/kernels/FOLDER_NAME/kernel.json as desired.
4. Install for current user with jupyter kernelspec install --user ~/my_custom_jupyter_kernels/share/jupyter/kernels/FOLDER_NAME.

Performance testing:

• The %%timeit magic allows for quick performance testing of a given cell.

Convert notebook to .py script:

• jupyter nbconvert --to script NOTEBOOK_NAME.ipynb

Install Vim mode via jupyter-vim-binding:

# Create required directory in case (optional)
mkdir -p $(jupyter --data-dir)/nbextensions
# Clone the repository
cd $(jupyter --data-dir)/nbextensions
git clone https://github.com/lambdalisue/jupyter-vim-binding vim_binding
# Activate the extension
jupyter nbextension enable vim_binding/vim_binding
