Question

我和nltk有错误，我不能再打开以前的项目了：

from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize

example_sent = "This is a sample sentence, showing off the stop words filtration."

stop_words = set(stopwords.words('english'))

word_tokens = word_tokenize(example_sent)

filtered_sentence = [w for w in word_tokens if not w in stop_words]

filtered_sentence = []

for w in word_tokens:
    if w not in stop_words:
        filtered_sentence.append(w)

print(word_tokens)
print(filtered_sentence)

当我运行这个时我得到了这个错误

错误并没有在这里结束它也会影响我使用nltk的所有其他项目以及当我运行第二个代码时

from nltk.tokenize import sent_tokenize, word_tokenize

EXAMPLE_TEXT = "Hello Mr. Smith, how are you doing today? The weather is great, and Python is awesome. The sky is pinkish-blue. You shouldn't eat cardboard."

print(sent_tokenize(EXAMPLE_TEXT))
print(word_tokenize(EXAMPLE_TEXT))


for i in word_tokenize(EXAMPLE_TEXT) :
    print (i)

我得到了相同的上一个错误，第二个代码在之前完美运行，

python nltk模块正在创建它自己的错误
