Thank you. Yes, I did get the sentencepiece error when I initially switched to MarianTokenizer.from\_pretrained(), but all hunky dory once I installed it.

Now my issue is that these models don’t work with DataParallel anymore, but that is another issue ([174223](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fhelsinki-nlp-throws-stopiteration-within-dataparallel%2F174223))(throws a StopTermination attempting to access self.model.device in its bowels). I may have to hand-jam my own threads for parallel inference (I had to do that for the ModernBERT models a while back, so code reuse is king!).
