I think what you are seeing here is an instance of the bug reported here:

> [@Beta 7 - Glove Word Vector](https://community.konduit.ai/t/beta-7-glove-word-vector/540):
>
> Hi We were using DL4J Beta6 version to load Glove 300d word vector file. It stopped working after upgrading to beta7. I posted this same question in Gitter and was given this commit history [Remove GloVe (#437) · eclipse/deeplearning4j@2cdb2b3 · GitHub](https://github.com/eclipse/deeplearning4j/commit/2cdb2b344704956098d97a422df8aacff384a024). Seems the support for Glove was removed in Beta7. Is that the case? However the beta7 documentation shows the file can be loaded using the loadTxtVectors method. [https://deeplearning4j.konduit.ai/language-processing/word2vec#glove-global-vect…](https://deeplearning4j.konduit.ai/language-processing/word2vec#glove-global-vectors)

It is already fixed in the current [SNAPSHOT version](https://deeplearning4j.konduit.ai/config/config-snapshots). But the linked thread also contains a workaround that you can use without switching to snapshots.
