Following the official documentation from fairseq, I tried to load the model with the following command:

from fairseq import checkpoint_utils
checkpoint_utils.load_model_ensemble("tupe_ckp/model.pt")

And, got the following error:

This file pt-data-0508/dict.txt is different from the already provided dict.txt file?

We use different data processing pipeline (and model code) as fairseq.
you cannot use our ckp in official fairseq.

[guolinke]

we had released dict.txt with model checkpoint: https://guolinke.blob.core.windows.net/tupe/tupe_ckp.tar.gz

Thank you for the response! I am using this repo modified version of fairseq. I was able to load the model altering where fairseq looks for dict.txt in that way:

from fairseq import checkpoint_utils
checkpoint_utils.load_model_ensemble("tupe_ckp/model.pt", {"data": "tupe_ckp"})

Concerning the pre-processing, can I run the scripts already provided to perform it and use the model as I loaded it, or would it be wrong?

[guolinke]

I guess load_model_ensemble will load args part saved in checkpoint. maybe you can try to reset args in tupe_ckp/model.pt.
