NameError: name 'master_bar' is not defined

Inizia riproducendo la chiamata `export_point_dataset` dal traceback e ispeziona `fastprogress/fastprogress.py` in corrispondenza dell’avviso relativo a `ipywidgets` e `arcgis/learn/_utils/pointcloud_data.py` alla riga 854, dove viene usato `master_bar`. Il lavoro è completato quando l’esportazione del dataset di punti non genera più `NameError: name 'master_bar' is not defined` quando si verifica l’avviso di importazione del widget.

Scritto dal modello di indicizzazione a partire dal testo della issue.
