As discussed:
1 Configure the template using a file to eliminate the need for additional coding.
2 move the code from example to autoround
3 Refine the cache code in AutoRound to improve generalizability for new models with train_batch_size=1.

4 refine all the examples of vlm

Please enhance the code by adding some comments and better add a README to include instructions on how to prepare llava dataset , support new models, etc. in this folder. Additionally, better test the code with an unseen model to evaluate its generalization capabilities.
