# rinna/japanese-clip-vit-b-16 |
|
|
|
 |
|
|
|
This is a Japanese [CLIP (Contrastive Language-Image Pre-Training)](https://arxiv.org/abs/2103.00020) model trained by [rinna Co., Ltd.](https://corp.rinna.co.jp/). |
|
|
|
Please see [japanese-clip](https://github.com/rinnakk/japanese-clip) for the other available models. |

# How to use the model |
|
|
|
|
|
1. Install package |
|
|
|
```shell |
|
$ pip install git+https://github.com/rinnakk/japanese-clip.git |
|
``` |
|
|
|
2. Run |
|
|
|
```python |
|
import io |
|
import requests |
|
from PIL import Image |
|
import torch |
|
import japanese_clip as ja_clip |
|
|
|
device = "cuda" if torch.cuda.is_available() else "cpu" |
|
|
|
|
|
model, preprocess = ja_clip.load("rinna/japanese-clip-vit-b-16", cache_dir="/tmp/japanese_clip", device=device) |
|
tokenizer = ja_clip.load_tokenizer() |
|
|
|
img = Image.open(io.BytesIO(requests.get('https://images.pexels.com/photos/2253275/pexels-photo-2253275.jpeg?auto=compress&cs=tinysrgb&dpr=3&h=750&w=1260').content)) |
|
image = preprocess(img).unsqueeze(0).to(device) |
|
encodings = ja_clip.tokenize( |
|
texts=["犬", "猫", "象"], |
|
max_seq_len=77, |
|
device=device, |
|
tokenizer=tokenizer, # this is optional. if you don't pass, load tokenizer each time |
|
) |
|
|
|
with torch.no_grad(): |
|
image_features = model.get_image_features(image) |
|
text_features = model.get_text_features(**encodings) |
|
|
|
text_probs = (100.0 * image_features @ text_features.T).softmax(dim=-1) |
|
|
|
print("Label probs:", text_probs) # prints: [[1.0, 0.0, 0.0]] |
|
``` |
|
|
|
# Model architecture |
|
The model was trained a ViT-B/16 Transformer architecture as an image encoder and uses a 12-layer BERT as a text encoder. The image encoder was initialized from the [AugReg `vit-base-patch16-224` model](https://github.com/google-research/vision_transformer). |
|
|
|
# Training |
|
The model was trained on [CC12M](https://github.com/google-research-datasets/conceptual-12m) translated the captions to Japanese. |
