ModuleNotFoundError NLTK

Question

标记化工作正常，但当我尝试进行命名实体识别时，namedEnt = ne_chunk(tagged，binary=True)

它给出了以下错误我确实使用pip install NumPy从cmd安装了numpy，但仍然给出了错误

import nltk
from nltk.corpus import state_union
from nltk.tokenize import PunktSentenceTokenizer, word_tokenize
from nltk.chunk import ne_chunk

train_text = state_union.raw("2005-GWBush.txt")
sample_text = state_union.raw("2006-GWBush.txt")
# print(train_text)


custom_sent_tokenizer = PunktSentenceTokenizer(train_text)
tokenized = custom_sent_tokenizer.tokenize(sample_text)


def process_content():
    for i in tokenized:
        words = word_tokenize(i)
        tagged = nltk.pos_tag(words)
        namedEnt = ne_chunk(tagged, binary=True)
        print(namedEnt)


process_content()

错误：

ModuleNotFoundError: No module named 'numpy'

Answer 1

通过pip install numpy安装numpy，然后通过import numpy as np导入它
