Problem running BioGTP-Large

[fran-jag]

Everytime I try to run the BioGPT-Large I get the following error:

RuntimeError: Error(s) in loading state_dict for TransformerLanguageModel:
size mismatch for decoder.embed_tokens.weight: copying a param with shape torch.Size([57717, 1600]) from checkpoint, the shape in current model is torch.Size([42384, 1600]).
size mismatch for decoder.output_projection.weight: copying a param with shape torch.Size([57717, 1600]) from checkpoint, the shape in current model is torch.Size([42384, 1600]).

Any ideas how to fix this?
Thx
