Demystifying Jupyter

En esta charla profundizaremos en Jupyter, una importante herramienta y entorno de trabajo open source orientado a científicos, que está revolucionando la forma de trabajar en el mundo de los datos. Veremos qué es realmente, cómo funciona y lo que esconde esta misteriosa Black Box.

1. DEMYSTIFYING JUPYTER
2. HEY THERE!
3. I am Melissa Escobar Gutiérrez Live lover Passionate for maths, books, technology, music and nature
4. Intros require brevity, kernels protocols complexity, Jupyter much gravity will try to bring some levity A POEM
5. Store, process and interpret large volumes of data at high speed BIG DATA
6. 2014: Arises as an evolution of the IPython project It’s name: a tribute to Galileo HISTORY A little of
7. Fernando Pérez & Brian Granger
9. Currently in use at
10. HOW DOES JUPYTER NOTEBOOK WORK?
11. Lets play a game But Lets play a game BEFORE...
12. MAGIC?
13. #include <stdio.h> int main() { float i; for (i=0; i<i+1; i++){ i++; } printf("%f", i); return i; } SOME CODE
14. 16,777,216.0000
17. JUPYTER NOTEBOOK INSIDE JUPITER KERNEL JUPYTER NOTEBOOK SERVER BROWSER
18. WHAT IF WE DE-COUPLE EXECUTION FROM INPUT?
20. ANALOGY Speaks Web Server Client Browser Kernel Speaks HTTP Jupyter Protocol Images from flaticon.com
21. KERNEL BASED SYS JUPITER KERNEL Execution engine for a specific language. IPython is the default kernel.
22. WHAT IS A KERNEL ? Accepts messages Performs actions Sends out results Send Input Execution Result
23. WHAT IS A CLIENT ? Connects to exactly 1 kernel Send messages to kernel based on user actions Display kernels messages when appropriate
24. A Jupyter notebook is a dictionary with a few keys: metadata (dict) nbformat (int) nbformat_minor (int) cells (list) Top-level structure
25. { "metadata" : { "kernel_info": { # if kernel_info is defined, its name field is required. "name" : "the name of the kernel" }, "language_info": { # if language_info is defined, its name field is required. "name" : "the programming language of the kernel", "version": "the version of the language", "codemirror_mode": "The name of the codemirror mode to use [optional]" } }, "nbformat": 4, "nbformat_minor": 0, "cells" : [ # list of cell dictionaries ], }
26. { "cell_type" : "type", "metadata" : {}, "source" : "single string or [list, of, strings]", }
27. CONCLUSION
