- # GIT (GenerativeImage2Text), base-sized
13
-
14
- GIT (short for GenerativeImage2Text) model, base-sized version. It was introduced in the paper [GIT: A Generative Image-to-text Transformer for Vision and Language](https://arxiv.org/abs/2205.14100) by Wang et al. and first released in [this repository](https://github.com/microsoft/GenerativeImage2Text).
15
-
16
- Disclaimer: The team releasing GIT did not write a model card for this model so this model card has been written by the Hugging Face team.
17
-
18
- ## Model description
19
-
20
- GIT is a Transformer decoder conditioned on both CLIP image tokens and text tokens. The model is trained using "teacher forcing" on a lot of (image, text) pairs.
21
-
22
- The goal for the model is simply to predict the next text token, giving the image tokens and previous text tokens.
23
-
24
- The model has full access to (i.e. a bidirectional attention mask is used for) the image patch tokens, but only has access to the previous text tokens (i.e. a causal attention mask is used for the text tokens) when predicting the next text token.
25
-
26
- ![GIT architecture](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/git_architecture.jpg)
27
-
28
- This allows the model to be used for tasks like:
29
-
30
- - image and video captioning
31
- - visual question answering (VQA) on images and videos
32
- - even image classification (by simply conditioning the model on the image and asking it to generate a class for it in text).
33
-
34
- ## Intended uses & limitations
35
-
36
- You can use the raw model for image captioning. See the [model hub](https://huggingface.co/models?search=microsoft/git) to look for
37
- fine-tuned versions on a task that interests you.
38
-
39
- ### How to use
40
-
41
- For code examples, we refer to the [documentation](https://huggingface.co/docs/transformers/main/model_doc/git#transformers.GitForCausalLM.forward.example).
42
-
43
- ## Training data
44
-
45
- From the paper:
46
-
47
- > We collect 0.8B image-text pairs for pre-training, which include COCO (Lin et al., 2014), Conceptual Captions
48
- (CC3M) (Sharma et al., 2018), SBU (Ordonez et al., 2011), Visual Genome (VG) (Krishna et al., 2016),
49
- Conceptual Captions (CC12M) (Changpinyo et al., 2021), ALT200M (Hu et al., 2021a), and an extra 0.6B
50
- data following a similar collection procedure in Hu et al. (2021a).
51
-
52
- => however this is for the model referred to as "GIT" in the paper, which is not open-sourced.
53
-
54
- This checkpoint is "GIT-base", which is a smaller variant of GIT trained on 10 million image-text pairs.
55
-
56
- See table 11 in the [paper](https://arxiv.org/abs/2205.14100) for more details.
57
-
58
- ### Preprocessing
59
-
60
- We refer to the original repo regarding details for preprocessing during training.
61
-
62
- During validation, one resizes the shorter edge of each image, after which center cropping is performed to a fixed-size resolution. Next, frames are normalized across the RGB channels with the ImageNet mean and standard deviation.
63
-
64
- ## Evaluation results
65
-
66
- For evaluation results, we refer readers to the [paper](https://arxiv.org/abs/2205.14100).
