Empty ATTN in REST server mode

Support
1

I try start REST server with replace_unk mode.

th tools/rest_translation_server.lua -model es/final_epoch_release.t7 -port 5773 -replace_unk -phrase_table es/es-en.pt -withAttn

And send curl command:

curl -v -H “Content-Type: application/json” -X POST -d ‘[{ “src” : “hola” }]’ http://148..176.:5773/translator/translate

And recieve result:

Note: Unnecessary use of -X or --request, POST is already inferred.

  • Connected to 148..176. (148..176.) port 5773 (#0)

first make sure you run “luarocks install nn” first
then try to run your server without -withAttn and without the phrase_table options.

run the curl command again.

you confirm your model is a cpu release, right ?
