Free Translation Server with EASYNMT

Best Option is, run it with Docker:

sudo docker run -p 24080:80 -v /tmp:/cache -e EASYNMT_MODEL=m2m_100_418M -e TRANSFORMERS_OFFLINE=1 easynmt/api:1.1-cpu
The option "-e TRANSFORMERS_OFFLINE=1" allow to run the Server offline. Only once the Language for translation is first time requested, the Server needs Web Access to Download the Source Files.
