How to perform validation during the fine-tune training process on llava_llama3_8b_instruct_full_clip_vit_large_p14_336_lora_e1_gpu8_finetune?

I have been fine-tuning the llava-llama3-8b-v1_1 model on my own dataset using the llava_llama3_8b_instruct_full_clip_vit_large_p14_336_lora_e1_gpu8_finetune_copy.py script. While the training phase performed well, I observed an absence of any validation process throughout the training, potentially culminating in overfitting concerns. It would be grateful if someone could offer some advice.
