Per esplorare tutte le interessanti funzioni che Polars ha da offrire, dovrai prima renderlo operativo.
In questo capitolo, ti spiegheremo:
-
Imposta il tuo ambiente di lavoro
-
Installa tutte le dipendenze necessarie per seguire gli esempi di questo libro in un ambiente virtuale utilizzando uv
-
Scopri come avviare e utilizzare JupyterLab, l'ambiente in cui eseguirai gli esempi di codice di questo libro.
-
Scopri come installare Polars e le sue dipendenze opzionali per i tuoi progetti.
-
Scopri come configurare Polars a tuo piacimento
-
Scopri come compilare Polars dai sorgenti e cosa fare nei casi limite in cui si lavora con dataset molto grandi o con processori vecchi
Si consiglia di seguire gli esempi di codice contenuti in questo libro: l'apprendimento di nuovi pacchetti tende a funzionare molto meglio quando si gioca con ciò che si è imparato, invece di limitarsi a leggere le possibilità.
Impostazione dell'ambiente
Per seguire questo libro, dovrai creare un ambiente. Per prima cosa scaricheremo i file del progetto, dopodiché installeremo uv, lo strumento necessario per essere operativi. uv è un gestore di progetti e pacchetti Python estremamente veloce, scritto in Rust. Utilizzando uv installerai le dipendenze del progetto necessarie per seguire gli esempi del libro.
