python-3.x - 如何在python中将大型二进制文件转换为pickle字典？

Question

我正在尝试将包含具有 300 个维度向量的阿拉伯语单词的大型二进制文件转换为泡菜字典

到目前为止我写的是：

import pickle
ArabicDict = {}
with open('cc.ar.300.bin', encoding='utf-8') as lex:
    for token in lex:
         for line in lex.readlines():
             data = line.split()
             ArabicDict[data[0]] = float(data[1])

pickle.dump(ArabicDict,open("ArabicDictionary.p","wb"))

我得到的错误是：

Traceback (most recent call last):
  File "E:\Dataset", line 4, in <module>
    for token in lex:
  File "E:\lib\codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 0: invalid start byte
