Missing contact-regression model file for esmc_600m_2024_12_v0

[aowuawu]

Hi team,

First, thank you for your amazing work on ESM models!

I'm trying to use the esmc_600m_2024_12_v0.pth model downloaded from Hugging Face, but encountered a missing dependency: the corresponding contact regression file esmc_600m_2024_12_v0-contact-regression.pt doesn't appear to be available in the repository.

Could you please:

Confirm if this file is required for standard usage?

Provide guidance on how/where to obtain it? (e.g., separate download link, generation script)

Or suggest alternative approaches if this file is deprecated?

Additional context:

Hugging Face repo checked: https://huggingface.co/EvolutionaryScale/esmc-600m-2024-12/tree/main/data/weights

ESM version: fair-esm 2.0.0

Environment: pytorch 2.6.0 CUDA 12.4

Thank you for your support!
