Propose to print error information when import models

[SDaoer]

In the file /root/lmms-eval/lmms_eval/models/__init__.py, no output is printed if an ImportError occurs. This can lead to confusion for users who encounter a ValueError stating 'Attempted to load model '...', but no model for this name found!' in the file /root/lmms-eval/lmms_eval/api/registry.py, specifically at line 32, within the get_model function. This error might actually be triggered by a previous ImportError from {model}.py, but because the import error doesn’t display any associated messages, users remain unaware of the underlying issue.

recommend:

for model_name, model_class in AVAILABLE_MODELS.items():
    try:
        exec(f"from .{model_name} import {model_class}")
    except ImportError as e:
        print(f"Failed to import {model_class} from {model_name}: {e}")
        pass
