Fairseq metrics fails to load : cannot load the model.

[gg4u]

Hi @mhagiwara, I successfully installed fairseq-0.12.2, but jupyter lab cannot loading it.

Have you met this issue ?
Could you help? I am trying to use the classifier demo.

I tried to install fairseq as per instruction, but having issue in loading:
import fairseq.checkpoint_utils

ImportError: cannot import name 'metrics' from 'fairseq' (unknown location)

I tried here :
OFA-Sys/OFA#305

but no success.

I also had some problem with the fairseq version specified in the instruction, but installing with pip worked for me.
That is: pip install fairseq
Could you remove the installed fairseq and install it with pip and see if this solves your problems?

Hi @ciaua thanks a lot for your help.
Unfortunately it does not work for me:

I tried:
pip install fairseq --no-cache-dir to ensure it will install from the internet and not from the cached version,
but no success:

from fairseq import metrics # fail ImportError: cannot import name 'metrics' from 'fairseq' (unknown location)
import fairseq.checkpoint_utils # ImportError: cannot import name 'metrics' from 'fairseq' (unknown location)

We have ported the pretrained models to TorchAudio and Onnx from the original fairseq models: https://github.com/earthspecies/aves#ported-versions

You can try if this solves the fairseq dependency issue. However, you will need to install torchaudio or onnxruntime

Hi @gg4u @ciaua Sorry for not responding earlier. Seems like the issue is that if you install fairseq right under your working directory your import gets confused and may encounter import issues. I suggest installing fairseq under a sibling (or totally unrelated) directory. I updated README to make this point clear. Thanks for pointing this out!
