Yes, you can. The newest version commit supports directly loading lora model.
Can you share the script for it please. Do we just have to change the current model path to lora path. I did it but didn't work at all.
can you share the exact script that we can do the inference with the LoRA weights. please.
Yes, you can. The newest version commit supports directly loading the Lora model.
Can you share the script on how to load the Lora model directly? I already finished the fine-tuning. And got those files. But I don't know how to do the inference with these.

Hello! I have the same problem. Have you solved it?

@thisurawz1 Through the following code, I successfully loaded the LoRA fine-tuned model for inference. Hope this helps you.

Hello! I have the same problem. Have you solved it?
yes. you have to update the videollama2 repository to the latest commit. then use the following script. just have to change the model path in the original inference script. thats all.

Dear author,I used your lora checkpoint folder structure and loading example code(https://github.com/DAMO-NLP-SG/VideoLLaMA2/issues/36) to my fintue_qlora inference code on my own experiment video data, but it still has some errors.The old inference code of readme file is work.I just put your code in the code.

You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

Can you share the script on how to load the Lora model directly? I already finished the fine-tuning. And got those files. But I don't know how to do the inference with these.
@thisurawz1 Through the following code, I successfully loaded the LoRA fine-tuned model for inference. Hope this helps you.

Hello,I'm a phD student from ZJU, I also use videollama2 to do my own research,we create a WeChat group to discuss some issues of videollama2 and help each other,could you join us? Please contact me: WeChat number == LiangMeng19357260600, phone number == +86 19357260600,e-mail == liangmeng89@zju.edu.cn.
I have already fine-tuned the videollama2 for a custom dataset using qlora. after fine-tuning got the above files. now, how can I make the inference with those weights/ models? how can I use this finetune weights/ model with the inference script you provided?
Looking forward to a solution as soon as possible. thank you.
