[Bug] pip install vizseq error

[xsfang]

🐛 Bug

I am installing vizseq in a colab notebook and got an error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
torchaudio 2.3.0+cu121 requires torch==2.3.0, but you have torch 1.13.1 which is incompatible.
torchtext 0.18.0 requires torch>=2.3.0, but you have torch 1.13.1 which is incompatible.
torchvision 0.18.0+cu121 requires torch==2.3.0, but you have torch 1.13.1 which is incompatible.

How to solve this problem?
Thanks,

I am also getting this error:

Resolved on the latest main branch by #109: plain pip install vizseq no longer installs or pins PyTorch because the heavy embedding dependencies were moved to the optional embeddings extra. This avoids replacing Colab’s preinstalled Torch during a base install. Note that the embeddings extra still requires its dependency set separately.
