Project is unrunnable due to incomplete local `fairseq` and bugs

[c1ya0]

Hi,

I have spent a very long time trying to run this project and have discovered a deep dependency issue that makes it unrunnable.

1. The fairseq directory bundled with this repository is incomplete. It is missing the entire fairseq/data/graph module, which I have confirmed by inspecting the cloned files. This makes it impossible to run the code as any attempt to patch the files fails because they do not exist locally.

2. If I install an official version of fairseq via pip, the Python interpreter uses that version instead. The training script then starts but immediately crashes with an AttributeError: 'NoneType' object has no attribute 'max' inside that official fairseq/data/graph/collator.py.

3. This AttributeError happens with both the provided preprocessed data and with data I preprocessed myself from the raw OGB files, confirming it's a code bug.

Conclusion: The local fairseq copy is broken/incomplete. The training code is also incompatible with the official fairseq library due to a bug in the data collator.
Could you please provide a working, complete version of the fairseq dependency required for this project, or patch the bug? The project is currently not runnable.

Thank you.
