Datei "/home/july/PythonProjects/test/tokenize.py", Zeile 3, in
aus nltk.tokenize importiere regexp_tokenize, wordpunct_tokenize, blankline_tokenize

Es gibt zufällig ein weiteres Skript mit dem gleichen Namen, nach dem Python sucht. Python war verwirrt über das Skript aus dem Paket und Ihr eigenes Skript, da es mit der Suche in dem Ordner beginnt, in dem Sie sich befinden.
Ändern Sie also einfach Ihr eigenes Skript in einen anderen Namen.

Es kann funktionieren, nachdem ich das Terminal neu gestartet habe. Ich weiß nicht warum.

Ich habe einen Fehler gemacht, tut mir leid.
Wenn jemand from nltk.tokenize import sent_tokenize in ide mit einem Fehler verwendet, können Sie versuchen, es in der Konsole auszuführen.
