ValueError: Fan in and fan out can not be computed for tensor with less than 2 dimensions

请问这个是什么原因啊，在TEXT.build_vocab(train, vectors=vectors)这一句报错了。 我看了下vectors的格式也正确，pytorch0.4.1版本。暂时不知道解决办法，求问，谢谢。

找到https://github.com/ShuangXieIrene/ssds.pytorch/issues/9 ，但并没有解决问题。

我记得我之前也遇到了这个问题，是torchtext的版本问题，更换torchtext版本为0.2.3 问题解决
