Paper provided example can not be reproduced !!

[HuangChiEn]

I have draw the example from the README.md.

1. load-8bit response is acceptable, but it didn't give me any explanation.
   

2. I think load-8-bit may decrease performance, so i exec in fp16 mode only (no serious quantization). But i got the worse results.. it still doesn't explain.
   
   

bunch of out-of-control [SEG] token is pop out?

I have encountered several issue, so i follow transformer version to Llava, and modify the code according to this issue
haotian-liu/LLaVA#968

The real problem i afraid affect the decoding strategy is that
salesforce/LAVIS#571.

So, i have replace all private function (i.e. _expand_mask) to object to pass the static check of python.
Moreover, i have place RuntimeError to the begin of all function which will use it (but i didn't get any RuntimeError).
So, that's mean all private function will not be used during inference.

Any suggestion will be appreciated!!

Did not u see the train data.
The GT for LLaVA to output is trained to be "Sure, it's the <seg>."
It was trained to to say like that, so you cannot force it to output the explaination.
Although the writer's demo seem to be wrong.

yeah, i agree your point, model barely can not generate the phrase what it never seen in training set.
However, the demo examples not just give one example.

So, i wonder how to reproduce such inference results by adjusting the prompt (we just see it trigger the prompt by 'explain why') ?

On the other hand, the reproduced results also appears the error-prone output, for example, it generate massive [SEG] tokens in console. It's also one of my question.

我觉得可以不用纠结这个问题，如果你希望得到demo中的效果，可以考虑调研一下LISA++，LISA++可以很好的完成demo中的任务，对话更自然一些

有查到你提的那篇論文，但我找不到它的github；你提到LISA++可以很好的完成demo中的任务，那你知道在哪取得LISA++的github嗎 (source code和reproduce的權重) ?

[jifeng35]

好像确实没有代码和权重，LISA++的论文里也没提到

then, let's wait and see that will LISA author give any comment ~
