Pymarian Webapp

This is a webserver for pymarian demo

Features Supported:

• Test Marian models locally with ease
• Compare multiple models
• Live translation demo (see translation as you speak or type)

Setup/installation

pymarian-webapp requires Python 3.9 or later.

git clone https://github.com/marian-nmt/pymarian-webapp
cd pymarian-webapp

# optionally create an env
python3 -m venv venv
. venv/bin/activate

# install
pip install .

Start the server

You need to provide the model with a config file which tells it where to find models. Two models types are supported: a path to a local Marian model, or the Microsoft Translator API, which requires an API subscription key.

pymarian-webapp -c pymarian_webapp/examples/basic.yml

This starts a service on http://localhost:6060 by default. See the config file for other model options.

More options are available and can be see via the -h flag:

usage: pymarian-webapp [-h] [-d] [-p PORT] [-ho HOST] [-b BASE] [-c CONFIG] [-e] [-me [METRICS ...]]
