Support for Python 3.11

[thyripian]

🐛 Bug

Making recommended modifications to config.py from separate issue to allow 3.11 compatibility break fairseq and or runtime compatibility with hydra.

Windows 10 machine, Python 3.11.3, fairseq==0.12.2, omegaconf==2.0.6, hydra-core==1.0.7, running LASER3 embed models and nllb-200-distilled-600M.

Steps to reproduce the behavior (always include the command you ran):

1. Run cmd './embed.sh [inp_file] [out_file] gle_Latn'
2. See error

Traceback in attached image

Expected behavior

Expected process to run as intended.

Environment

• fairseq Version (e.g., 1.0 or main): 0.12.2
• PyTorch Version (e.g., 1.0): 2.0.1
• OS (e.g., Linux): Windows 10
• How you installed fairseq (pip, source): git clone, pip install --editable
• Build command you used (if compiling from source): python setup.py build develop
• Python version: 3.11.3
• CUDA/cuDNN version: n/a
• GPU models and configuration: n/a
• Any other relevant information: I've been trying to figure this out since Friday (6/2/2023). Please help. I'd like to get some kind of progress by the end of the day tomorrow.

Issue still present. Got it on windows 11 with environment conda create -n test_env python=3.11.8 anaconda:

Got around by switching to python version 3.9 conda create -n test_env_3_9 python=3.9 anaconda and everything works fine.
