maybe it's because the version of fairseq

I have been trying to fix this by modifying fairseq to support python 3.11, but it does not seem to be working. See https://github.com/wtf-things/fairseq-311/commits/main and facebookresearch/fairseq#5062.

Am I doing something wrong? I downloaded the latest github release file and extracted it, then I ran

python3 -m pip install -r requirements.txt
python3 -m pip install git+https://github.com/wtf-things/fairseq-311/
python3 infer-web.py

[supercraaazy]

ok now after long time of using codes that may fix my issue. now i am getting this message :

[HardikJain02]

I tried this.

Before
common: CommonConfig= CommonConfig()

After
common: CommonConfig = field(default_factory= CommonConfig())

In the same way, you will have to do it for all the fields required. After that, I got another error. So I uninstalled the fairseq. this absurdism is making me more of a stoic daily.

The official fix of fairseq is too slow. I have created a fixed version of fairseq that works properly on Python 3.11.
You can try this If you need.

pip install git+https://github.com/One-sixth/fairseq.git

[CrabbyDisk]

I am having the same issue.

@CrabbyDisk @theoparis
Hey guys, I got same problem and I fixed this by install python 3.10.11

During requirement installation, I found some package can only run under <python 3.11

https://www.python.org/ftp/python/3.10.11/python-3.10.11-amd64.exe

Hope this can help you, enjoy!

Here is the solution for those using Python3.11
