[ayush1298]

closes #3693

[Copilot]

Pull request overview

This PR adds a compute_missing parameter to the get_model_meta function to allow computing missing model metadata attributes (number of parameters and memory usage) from the HuggingFace Hub when they are not available in the model registry.

Key Changes:

• Added compute_missing parameter to get_model_meta function signature with a default value of False
• Added logic to compute missing n_parameters and memory_usage_mb attributes when requested
• Updated function documentation to describe the new parameter

@Samoed How the typechecking tests suddenly failing in all PRs?
getting this error:

mteb/models/get_model_meta.py:133: error: "type[ModelMeta]" has no attribute "from_hf" [attr-defined]

[Samoed]

It was added to main. It's not failing in all prs, but if there is an error it will fail. Currently, the reason is that you call method that not existing. I fixed it

@Samoed Do we have to add tests for this, or is it good?

[Samoed]

Yes, it's better to add a test
