我在使用GloVe实现词到向量映射时遇到了麻烦。我的代码似乎工作正常，但有一个奇怪的问题：尝试将一个特定的单词 - 'the' 映射到它的向量表示时出现错误。我不知道为什么会这样。
这是我读取 GloVe 文件的代码：
def read_glove_vecs(glove_file):
with open(glove_file, 'r', encoding='utf-8', errors='ignore') as f:
words = set()
word_to_vec_map = {}
for line in f:
line = line.strip().split()
curr_word = line[0]
words.add(curr_word)
word_to_vec_map[curr_word] = np.array(line[1:], dtype=np.float64)
i = 1
words_to_index = {}
index_to_words = {}
for w in sorted(words):
words_to_index[w] = i
index_to_words[i] = w
i = i + 1
return words_to_index, index_to_words, word_to_vec_map
如您所见，上面的函数返回变量“word_to_vec_map”，它应该将训练集中的单词映射到它们的 GloVe 表示。
这是训练集中的一个片段：
I am proud of your achievements,2,,
Miss you so much,0,, [0]
food is life,4,,
I love you mum,0,,
Stop saying bullshit,3,,
congratulations on your acceptance,2,,
The assignment is too long ,3,,
I want to go play,1,, [3]
似乎我能够使用 word_to_vec_map 映射单词：
print(word_to_vec_map['proud'])

有谁知道为什么会这样？为什么我不能映射这个特定的词？
