Changes

• Due to compatibility consideration, fine-tuning vision language models (VLMs) requires transformers>=4.35.0.dev0, try pip install git+https://github.com/huggingface/transformers.git to install it.
• visual_inputs has been deprecated, now you do not need to specify this argument.
• LlamaFactory now adopts lazy loading for multimodal inputs, see #5346 for details. Please use preprocessing_batch_size to restrict the batch size in dataset pre-processing (supported by @naem1023 in #5323 ).
• LlamaFactory now supports lmf (equivalent to llamafactory-cli) as a shortcut command.
