How to use cross-lingual embeddings in OpenNMT-py?

I have obtained cross-lingual embedding with MUSE toolkit, and want to use it as pretrained embeddings in OpenNMT, how can I do this ? Is it the same operations as using monolingual pretrained embeddings as mentioned in the tutorial of OpenNMT? That is, first preprocessing data with, got, then ./tools/ -emb_file_both path/to/cross-lingual embedding -dict_file data/ -output_file data/embeddings, and got the pretrained encoder & decoder embeddings once again, finally training the model with the new encoder & decoder embedding?

Is my understanding correct? Could anybody help me solve the problem please? Thanks very much!!

This looks like the correct way to do it. What specific problem did you encounter?
