在IPython中控制檯我輸入from nltk.book import，我得到了幾個LookupErrors。下面顯示了我得到的代碼。LookupError：從nltk.book進口*
*** Introductory Examples for the NLTK Book ***
Loading text1, ..., text9 and sent1, ..., sent9
Type the name of the text or sentence to view it.
Type: 'texts()' or 'sents()' to list the materials.

我可以知道爲什麼我會得到這些錯誤嗎？
嘗試使用'nltk.dowwnload（）'這將打開一個面板。在那裏'Corpora'下載'gutenberrg'書/語料庫並再次嘗試你的命令 – Vaulstein
謝謝！有效！下載的錯誤消息中提到的語料庫。我是否需要其他語料庫，以後再不下載？ –
