MTLApi

XUnity.AutoTranslator compatible REST Service powered by HuggingFace Transformers

Getting Started

Install poetry: https://python-poetry.org/docs/

1. Install required dependencies

poetry install

2. Change the model name at mtlapi/constants/language.py and add language mapping as required at mtlapi/constants/language.py

3. Start the server

poetry run dev

4. Edit the AutoTranslatorConfig.ini for XUnity.AutoTranslator (usually at config/AutoTranslatorConfig.ini)

[Service]
Endpoint=CustomTranslate

[Custom]

EnableShortDelay=False
DisableSpamChecks=False

Language Mapping

You can configure the language mapping in the mtlapi/constants/language.py file, but only if the model requires it. The dict key comes from the XUnity.AutoTranslator Config, which the service parsed from the request sent by AutoTranslator based on the AutoTranslatorConfig.ini configuration:

[General]
Language=en
FromLanguage=zh

and the value is based on the language mapped into the model. By default the value is mapped to Meta AI's NLLB 200. MarianMT based models do not require this for inference so you can just ignore it completely.
