How to make a googletrans translator tool for Agent

[dkbs12]

Hello,
I’m making the QA chatbot for my own use, but I haven’t found an appropriate translator model for my mother language from Huggingface.
So I decided to use googletrans API as a translator tool for Agent.
I’ve read the ‘Creating Custom Components’ guide and ‘Translator’ document to create a custom translator, but all the examples were made by transformers model(TransformersTranslator).
As you know googletrans is out of huggingface and can’t be imported from HF.
Could you let me know how to create a translator tool using googletrans API?

Hello @dkbs12 What language are you trying to translate? Maybe we can help finding a model.
If you would like to create your custom component, here are some ideas. You could use deep-translator, which also support google translator: https://github.com/nidhaloff/deep-translator#id1
pip install deep-translator

and then in your custom components translate method you would do the following:

from deep_translator import GoogleTranslator

translated = GoogleTranslator(source='auto', target='de').translate("keep it up, you are awesome")

inside of

def translate(
        self,
        results: Optional[List[Dict[str, Any]]] = None,
        query: Optional[str] = None,
        documents: Optional[Union[List[Document], List[Answer], List[str], List[Dict[str, Any]]]] = None,
        dict_key: Optional[str] = None,
    ) -> Union[str, List[Document], List[Answer], List[str], List[Dict[str, Any]]]:

For the custom component, I'd suggest that you simply copy https://github.com/deepset-ai/haystack/blob/main/haystack/nodes/translator/transformers.py to your own googletrans.py file and just rename the class and adjust the three methods.
