fastText的label有上限 #44

训练代码为

确定是分类问题吗?label数量这么大 |
我想做模糊文本到唯一id的映射,即使缺字多字依旧能尽可能匹配,为此专门做了汉字编码,希望对于相似字也能实现匹配

你这个应该去用词向量或者simhash之类的方案,不应该用文本分类 |
感谢建议,我尝试更换下方法 |

这是打印读取train的结果
可看到读取上限为185898,而train中我提供的label数为1300000+,为了排除数据问题,我将原本train以150000分割为9个文件,依次进行读取测试,结果均能正常返回label读取数,基本可排除是数据文件的问题
fastText是确定的设置了这个上限吗还是文件读取量有上限?原train文件有480MB大小,分割后最大为52MB
