How to choose the model size we want and run the local model path?

### Summary

Hello, very good tools. I had a question in using the biggest 1.1B model to get the representation of my molecules. I used the code below to successfully get the representation, but it dosen't work anymore. And I cannot find the usage in your latest version. “ clf = UniMolRepr(data_type='molecule',
remove_hs=False,
model_name='unimolv2',
model_size='1.1B',
load_model=local_model_path
)”

### Uni-Mol Version
