does anybody know a way to fix this error? Thanks!

@dsinkerii i don't think pytorch is even compatible with python 3.11

[lucidrains]

pytorch/pytorch#86566

[dsinkerii]

Oh, i see. I will try to downgrade it and see if this is going to help. Thanks!

[dsinkerii]

Yep, that was the issue! thanks!

@lucidrains pytorch 2.0 supports python 3.11, except for torch.compile. 3.11's JIT makes scripts start faster, so I've been using it a lot.

the problem reported here is unrelated to pytorch.

seems the @dataclass decorator from the Python standard library, underwent some kind of breaking change. this line is the one it's complaining about, I think:
https://github.com/facebookresearch/fairseq/blob/176cd934982212a4f75e0669ee81b834ee71dbb0/fairseq/dataclass/configs.py#L1129

the message says to use a factory for default initialization of fields. probably like this:

@dataclass
class FairseqConfig(FairseqDataclass):
-     common: CommonConfig = CommonConfig()
+     common: CommonConfig = field(default_factory=CommonConfig)

this is a Python 3.11 compatibility problem that needs to be raised against facebookresearch/fairseq has been raised already in facebookresearch/fairseq#5012.
