A question about the x dimension. about clip_prefix_caption HOT 7 CLOSED

Hi @tianjunyu0871 ,
There is two version of CLIP (Resnet and VIT)
Their encoding size is different - 500 and 640
I assume this is your issue

It should be solvable using different command line arguments

Is it helpful?

from clip_prefix_caption.

Thanked your reply.
Does the parameter is_rn represent resnet?But the following command appears is_rn?Is it a clerical error?

In addition, can you share the pre-training weights of MLP and the program evaluation code? Thank you so much!!

from clip_prefix_caption.

Yes this is an error
Thank you very much for pointing it out
I will fix it ASAP

We use the evaluation code as used in the OSCAR repository
Just replacing the JSON files with our JSONs

We already shared the weights of MLP - see "Inference Notebooks" section in the readme.

I tried to modify the prediction code and the following error occurred while loading the pre-trained Transformer data.

I don't know if there is a problem with my code. Can you share your code for forecasting with Transformer? Thank you very much!

from clip_prefix_caption.

Prediction with transformer is available in this notebook

I have gained a lot from your work, but I still have a few questions, and I hope to get your answers.
First question: I tried to remove the stoptoken, but the effect is not good, is there a good way to generate more than one sentence?
Second question: Have you tried using different GPT models? Such as GPT2-medium or GPT2-large . Is the difference significant?
Third question: what does the prefix_length_clip parameter mean in training?
Looking forward to your reply, thank you very much!

To generate more than one sentence you should replace the inference algorithm (e.g. beam search)
Using a variants of beam search you can produce different captions.

We haven't tried to use different GPT models.

prefix_length_clip control the transformer mapping network - size (in tokens) of the clip embedding, as some of the prefix is a learned const.
