Fairseq 0.2.1 - No wheels available for PyTorch 2.3.* and 2.4.*

[julianzaidi]

Hey,

I try to install fairseq2 following the instructions in the README but it seems that no wheels are available for PyTorch 2.3.* and 2.4.*

• Wheels for PyTorch 2.4.*
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.4.0/cu121
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.4.0/cu118

• Wheels for PyTorch 2.3.*
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.3.0/cu118
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.3.0/cu121
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.3.1/cu118
  https://fair.pkg.atmeta.com/fairseq2/whl/pt2.3.1/cu121

Wheels for PyTorch 2.2.* seems to be there (e.g. https://fair.pkg.atmeta.com/fairseq2/whl/pt2.2.2/cu121). As a result, I have PyTorch 2.4.0 installed but it is automatically removed and replaced by PyTorch 2.2.2 when I try to pip install fairseq2.

As a side note, wheels for the nightly builds are available (e.g. https://fair.pkg.atmeta.com/fairseq2/whl/nightly/pt2.4.0/cu121), but I need fairseq2 0.2.1 not 0.3.0.dev*

Are you planning on adding those wheels for the 0.2.* versions?

Thank you!

@cbalioglu, sorry for the spam if you are not the right person. Do you plan on adding those wheels in a near future?

Hi, wanted to bump this! The readme indicates that fairseq2 binaries are available for torch 2.5.1. The exact command in the readme:

pip install fairseq2 --extra-index-url https://fair.pkg.atmeta.com/fairseq2/whl/pt2.5.1/cu124

will just install the pypi fairseq2 as the provided url does 404's (as per OP's comment). The binaries DO exist for the nightly builds, but I also need for fairseq2 0.2.1.

Do this builds actually exist and the readme simply has the wrong URL, or are there no plans for fairseq2 to support newer torch versions and the "variants" / "nightly" sections of the readme have been intermixed erroneously?
