Hi, I am trying to use the embeddings.lua script to generate pre-trained word embeddings. However, after running something like:

th tools/embeddings.lua -lang en -dict_file data/demo.src.dict -save_data data/demo-src-emb

I get the following error:
.../torch/install/bin/luajit: tools/embeddings.lua:98: embedding file for language code 'en' was not found
stack traceback:
[C]: in function 'error'
tools/embeddings.lua:98: in function 'loadAuto'
tools/embeddings.lua:417: in function 'main'
tools/embeddings.lua:433: in main chunk
[C]: in function 'dofile'
.../torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:150: in main chunk
[C]: at 0x00405d50

Any ideas why this is happening? Thank you in advance for your help!
