我对伯特一无所知...但是导入和运行有些可疑。我认为您没有正确安装它或其他东西。我试图 pip 安装它并运行它:
from sklearn.metrics.pairwise import cosine_similarity
from bert_serving.client import BertClient
bc = BertClient()
print ('done importing')
它从未完成。看看 bert 的 dox,看看是否需要做其他事情。
在您的代码中,通常最好先读取所有内容,然后进行处理,因此请先分别导入两个列表,然后检查一些值,例如:
# check first five
print(words[:5])
此外,您需要寻找一种不同的方法来进行比较,而不是使用嵌套循环。您现在意识到您每次都在为每个关键字转换words 中的每个单词,这不是必需的,而且可能真的很慢。我建议您使用字典将单词与编码配对,或者如果您对此更满意,请使用其中的(单词,编码)创建一个元组列表。
在您启动并运行 Bert 后,如果这没有意义,请回复我。

这里有一段代码,其工作方式与您想做的类似。根据您的需要,您可以选择很多方法来保存结果等,但这应该可以帮助您开始使用“fake bert”
from operator import itemgetter
# fake bert ... just return something like length
def bert(word):
return len(word)
# a fake compare function that will compare "bert" conversions
def bert_compare(x, y):
return abs(x-y)
# Process words
with open("./word_data_file.txt", "r", encoding='utf8') as textfile:
words = textfile.read().split()
# Process keywords
with open("./keywords.txt", "r", encoding='utf8') as keyword_file:
keywords = keyword_file.read().split()
# encode the words and put result in dictionary
encoded_words = {}
for word in words:
encoded_words[word] = bert(word)
encoded_keywords = {}
for word in keywords:
encoded_keywords[word] = bert(word)
# let's use our bert conversions to find which keyword is most similar in
# length to the word
for word in encoded_words.keys():
result = [] # make a new result set for each pass
for kword in encoded_keywords.keys():
similarity = bert_compare(encoded_words.get(word), encoded_keywords.get(kword))
# stuff the answer into a tuple that can be sorted
result.append((word, kword, similarity))
result.sort(key=itemgetter(2))
print(f'the keyword with the closest size to {result[0][0]} is {result[0][1]}')
