Description

想要在自有中文检索数据集上应用internvideo2,看了下最接近的是vatex_cn中使用internvideo2_clip模型,但是在加载过程中遇到些疑问。

  1. 共计需要加载哪些ckpt?
    目前看是这几个组件
    chinese_alpaca_lora_7b
    InternVideo2-stage2_1b-224p-f4.pt
    1B_clip.pth
    internvl_c_13b_224px.pth
    配置文件如下
    tokenizer_path="chinese_alpaca_lora_7b",
    vision_ckpt_path="OpenGVLab__InternVideo2-Stage2_1B-224p-f4/InternVideo2-stage2_1b-224p-f4.pt",
    load_vision_ckpt_from_internvideo2_stage2=True,
    text_ckpt_path="internvl_c_13b_224px.pth"
    extra_ckpt_path="OpenGVLab__InternVideo2-CLIP-1B-224p-f8/1B_clip.pth"

但是找不到可以配置1B_clip.pth的地方,在demo中直接在config中设置pretrained_path还是在配置文件中设置extra_ckpt_path?

2.加载ckpt的代码不知道是不是有问题,我最终产出的排序是这样的,不太符合预期。目前使用的是在配置文件中设置extra_ckpt_path,也就是1里的配置

Research direction

Start with the vatex_cn example and its demo/config to trace how chinese_alpaca_lora_7b, InternVideo2-stage2_1b-224p-f4.pt, 1B_clip.pth, and internvl_c_13b_224px.pth are loaded. Compare the configured extra_ckpt_path and pretrained_path usage, then verify the resulting ranking on a Chinese retrieval dataset. Done means the checkpoint configuration is unambiguous and the loading path produces expected retrieval results.
