Embeddings.lua error

opennmt-lua
(Claudia) #1

Hello! I’m training a model using the docker version of OpenNMT Torch version. I’m trying to use pre-trained embedding I got from word2vec. I understand that I first have to serialise my embeddings. I want to do that using the provided script but I’m getting an error. Can you please help me to understand what the problem is?

this is my command
th tools/embeddings.lua -embed_type word2vec -embed_file /home/data/vectors\[text_99-14.uncapitalized.expr\]\[\].log -dict_file data/demo.src.dict -save_data /home/data/demo-src-emb

this is the error I’m having
