Like the title says, I require a Seq2SeqTrainer for my project, but the file/s on Github are not available and return a 404. I use this code to try and import it:
!wget https://raw.githubusercontent.com/huggingface/transformers/master/examples/seq2seq/seq2seq_trainer.py
If it's no longer available anywhere, what would be a good alternative as I want to use ROUGE as well.
