Inquiry about Embedding Concatenation in DeepSpeed-VisualChat

@yaozhewei First, I'd like to extend my gratitude for the incredible work you've been doing with DeepSpeedExamples. It's truly commendable and has been a great resource for the community.

As I was exploring the code, particularly the section where language and visual embeddings are concatenated, I came across something that prompted a question. I noticed in this line of code:

https://github.com/microsoft/DeepSpeedExamples/blob/60e412eaa7275212e240f31055fc8b814ebe653f/applications/DeepSpeed-VisualChat/utils/model/modeling_dsvl.py#L226

that img_pos_list is reversed during the insertion of the image embedding. However, it appears that cur_img is not reversed in the process. Could there potentially be a mismatch between the visual and text information due to this? I'm curious if this is intentional for alignment purposes or if it might be an oversight.

I would appreciate any clarification you can provide on this matter.
