Resulta que hay otro script con el mismo nombre que Python está buscando. Python se confundió sobre el script del paquete y su propio script porque comienza a buscar desde la carpeta donde se encuentra.
Así que simplemente cambie su propio script por otro nombre.

Puede funcionar después de reiniciar la terminal. No sé por qué.

Cometí un error, lo siento.
Si alguien usa from nltk.tokenize import sent_tokenize en ide con un error, puede intentar ejecutarlo en la consola.

me salvó la vida, Dios mío, después de cambiar mi nombre de archivo de secuencia de comandos de Python
