nllb-200-distilled-1.3B-easyproject

<!-- This model card has been generated automatically according to the information the Trainer had access to. You should probably proofread and complete it, then remove this comment. -->

This model is a fine-tuned version of facebook/nllb-200-3.3B on the EasyProject dataset.

Framework versions

• Transformers 4.29.2

• Pytorch 1.11.0+cu113

• Datasets 2.8.0

• Tokenizers 0.13.2

• Paper link: Frustratingly Easy Label Projection for Cross-lingual Transfer

• Github link: https://github.com/edchengg/easyproject

• Please use the transformers==4.29.2 library as Huggingface recently fixed a bug in NLLB tokenizer
