Model description

More information needed

How to use

First please make sure to install pip install transformers. First download model:

from transformers import M2M100ForConditionalGeneration, M2M100Tokenizer
import torch

def translate(input_text, lang):
    input_ids = tokenizer(input_text, return_tensors="pt")
    generated_tokens = model.generate(**input_ids, forced_bos_token_id=tokenizer.get_lang_id(lang))
    return tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)

model_name = "cartesinus/iva_mt_wslot-m2m100_418M-0.1.0-en-de"
tokenizer = M2M100Tokenizer.from_pretrained(model_name, src_lang="en", tgt_lang="de")
model = M2M100ForConditionalGeneration.from_pretrained(model_name)

Then you can translate either plain text like this:

print(translate("set the temperature on my thermostat", "de"))

or you can translate with slot annotations that will be restored in tgt language:

print(translate("wake me up at <a>nine am<a> on <b>friday<b>", "de"))

Limitations of translation with slot transfer:

Annotated words must be placed between semi-xml tags like this "this is <a>example<a>"
There is no closing tag for example "<\a>" in the above example - this is done on purpose to omit problems with backslash escape
If the sentence consists of more than one slot then simply use the next alphabet letter. For example "this is <a>example<a> with more than <b>one<b> slot"
Please do not add space before the first or last annotated word because this particular model was trained this way and it most probably will lower its results
