Error when build model

**Thanks for the great code, I got the following error message when doing the training:**

`vit_base_patch16_224_in21k
=> base model: vit_base_patch16_224_in21k

**TypeError: __init__() got an unexpected keyword argument 'default_cfg'`**

**My guess is it is a timm version problem, I wonder what is your timm version?**

The error occurs in ./slowfast/models/transformers/vit.py at line 469, where a call to create_model passes an unexpected 'default_cfg' argument. Check the timm library version used in the project's dependencies (e.g., requirements.txt or setup.py) and compare with the function signature in timm's factory.py and helpers.py. Look for recent changes in the timm API that might have removed or renamed this parameter. Running a version check and testing with different timm versions locally would be the first step.
