Hello when i execute the following code i get the following error (Windows 11)
`

m.cuda()
src_tokens = m.encode("COVID-19 is")
generate = m.generate([src_tokens], beam=5)[0]
output = m.decode(generate[0]["tokens"])
print(output)

I am getting the same issue when trying to run QA-PubMedQA-BioGPT-Large model using:

m = TransformerLanguageModel.from_pretrained(
    "checkpoints/QA-PubMedQA-BioGPT-Large",
    "checkpoint_avg.pt",
    "data",
    tokenizer="moses",
    bpe="fastbpe",
    bpe_codes="data/bpecodes",
    min_len=100,
    max_len_b=1024,
)

Hello @Kristian-A @Dontmindmes, were you ever able to fix this?

I'm having the same issue. I've fine tuned BioGPT on a relation extraction task, and the training with fairseq was just fine, but now I can't evaluate it.

[shodhak]

Was anyone able to solve this?
