生成的all_v2.csv在我的电脑上编码不是utf-8，而是gb2312，read_csv时encoding改为'gb18030'或‘gb2312’。

在执行train_d2v_model.py文件时，在36行总是会报编码错误。
line = line.decode('utf8').rstrip()

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb2 in position 7: invalid start byte

你好，我在阅读这个项目源码的时候，产生了一些疑惑，希望能帮忙解答一下。

在训练 d2v 模型的时候，为什么 dbow 模型要累积训练 2 次，而 dm 模型要累积训练 10 次呢？以及为什么要查看 cv 分数，查看 cv 分数是为了确定累积训练次数吗？

也就是下面这个截图的内容：

非常感谢！

有对应的数据库sql文件吗??
