PyData London News

An archive for the PyData London News

Creating new news slides

If you are using the Conda package manager, create an environment with the requisite dependencies and activate it using:

conda env create -f=environment.yml
source activate pydata-news

Otherwise, get a setup with Python 3 and Jupyter available by your preferred mechanism.

Create a new folder for the slides with a name based on the date of the meeting (see previous meetings' folder names), and create an IPython notebook inside the folder. Alternatively, copy the folder from a previous month and rename it, which may be easier.

Once you have made modifications/additions to the month's slides, convert it to a slideshow and serve it with:

jupyter nbconvert <name of ipynb file> --to slides --post serve

Bonus point: add --no-input to hide the input cells:

jupyter nbconvert <name of ipynb file> --to slides --no-input --post serve

Shared static assets

Common CSS and images now live in static/ and can be linked into each month's folder so we only maintain them once.

• Add your notebook in a new month folder as usual, and put any month-specific images under <month>/images/.
• Run python utils/link_static.py from the repo root. It hashes and replaces matching custom.css files and any *.png images that exist in static/images/ with symlinks. Files with different contents are left untouched.
• Edit shared CSS in static/css/ or drop/update shared images in static/images/ to update every linked month at once.
• On Windows you may need to enable Developer Mode or run a shell with elevated privileges to allow symlink creation.
