Segmentation fault with the provided inference code

[yankee624]

I installed the repo with the provided script:

git clone https://github.com/DAMO-NLP-SG/VideoLLaMA2
cd VideoLLaMA2
pip install -r requirements.txt
pip install flash-attn==2.5.8 --no-build-isolation

The commit I used was 0b1a87fa7ed056f3e5bdfbf12dcf7979c1ac10f8 which is recent one.

Then, without changing any code, I ran the following inference code provided by the repo:

You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.
You shouldn't move a model when it is dispatched on multiple devices.
Segmentation fault (core dumped)

Similar things happen with other model versions like Mixtral 8x7B, or the Base models. How should I fix it?

[wenrousha]

I also had this problem, have you solved it yet?

[yankee624]

@wenrousha Nope

[mhardik003]

Same error, please tell if anyone has solved this error.

[LiangMeng89]

I also had this problem, have you solved it yet?

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.

This was fixed for me, it was a version issue, deleting a redundant version of CUDNN.
