Title

pip install fairseq fails due to invalid metadata for PyYAML dependency in omegaconf

Issue Description

Environment:

• Ubuntu 22.04
• Conda environment: streamspeech
• Python 3.10
• GCC version: 12.3.0

Steps to Reproduce:

1. Create and activate conda environment:

   conda create -n streamspeech python=3.10 -y
   conda activate streamspeech

2. Install dependencies:

   conda install pytorch=2.0.1 torchvision torchaudio cudatoolkit=11.7 -c pytorch
   sudo apt-get update
   sudo apt-get install -y build-essential python3-dev
   pip install cython numpy
   pip install --upgrade pip setuptools
   pip install PyYAML

3. Check PyYAML version:

   python -c "import yaml; print(yaml.__version__)"
   # Output: 6.0.1

4. Try to install fairseq:

   pip install --editable ./ --no-build-isolation

Observed Behavior:

• The installation process fails with the following errors:

  WARNING: Error parsing dependencies of omegaconf: .* suffix can only be used with `==` or `!=` operators
      PyYAML (>=5.1.*)
              ~~~~~~^

Expected Behavior:
fairseq should be installed without errors.

Additional Information:

• PyYAML version: 6.0.1
• omegaconf version: 2.0.5
• hydra-core version: 1.0.7
• torch version: 2.3.1
• pip version: 23.1

Notes:

• The PyYAML dependency in omegaconf has an invalid metadata format that causes the error.
• Running as root might cause permissions and conflicts, but switching to a non-root user does not resolve the dependency issues.

Steps Tried:

1. Upgrading/downgrading pip, setuptools, and wheel.
2. Installing specific versions of PyYAML and omegaconf.
3. Setting up a new conda environment with specific versions of dependencies.
4. Verifying GCC installation and setting default versions.

Request for Help:
I need assistance in resolving this installation failure. Any guidance or solutions would be appreciated.

I believe it's due to a newer version of pip. I'm using pip 24.0, and it gives me the following warning but works fine:

DEPRECATION: omegaconf 2.0.6 has a non-standard dependency specifier PyYAML>=5.1.*. pip 24.1 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of omegaconf or contact the author to suggest that they release a version with a conforming dependency specifiers. Discussion can be found at pypa/pip#12063

I'd say downgrading pip is probably the easiest way, or try upgrading/editing omegaconf to see if they fixed the issue in a newer version, as is mentioned in the warning.

I see that you've tried downgrading pip, but I believe it should work as it's pip that is unhappy about the dependencies.

1.download .whl file of omegaconf>=2.0.5,<2.1.0 from PyPI: https://pypi.org/project/omegaconf/#history
2.unzip .whl or just copy omegaconf-version.dist-info/METADATA
3.modify Requires-Dist: PyYAML (>=5.1.*) as Requires-Dist: PyYAML >=5.1
4.save METADATA and put it back to .whl file
5.pip install your_whl_file
I tried to upgrade or downgrade my pip but it doesn't work, so maybe you can take "workaround"
