# Introduction |
|
This project aims to provide a better Chinese CLIP model. The training data used in this project consists of publicly accessible image URLs and related Chinese text descriptions, totaling 400 million. After screening, we ultimately used 100 million data for training. |
|
This project is produced by QQ-ARC Joint Lab, Tencent PCG. |

## Results |
|
We conducted zero-shot tests on [MUGE Retrieval](https://tianchi.aliyun.com/muge), [Flickr30K-CN](https://github.com/li-xirong/cross-lingual-cap), and [COCO-CN](https://github.com/li-xirong/coco-cn) datasets for image-text retrieval tasks. For the image zero-shot classification task, we tested on the ImageNet dataset. The test results are shown in the table below: |

# Getting Started |
|
## Installation Requirements |
|
Environment configuration requirements: |
|
|
|
* python >= 3.6.4 |
|
* pytorch >= 1.8.0 (with torchvision >= 0.9.0) |
|
* CUDA Version >= 10.2 |
|
|
|
Install required packages: |
|
```bash |
|
cd /yourpath/QA-CLIP-main |
|
pip install -r requirements.txt |
|
``` |
|
|
|
## Inference Code |
|
```bash |
|
export PYTHONPATH=/yourpath/QA-CLIP-main |
|
``` |
|
Inference code example： |
|
```python |
|
import torch |
|
from PIL import Image |
|
|
|
import clip as clip |
|
from clip import load_from_name, available_models |
|
print("Available models:", available_models()) |
|
# Available models: ['ViT-B-16', 'ViT-L-14', 'RN50'] |
|
|
|
device = "cuda" if torch.cuda.is_available() else "cpu" |
|
model, preprocess = load_from_name("ViT-B-16", device=device, download_root='./') |
|
model.eval() |
|
image = preprocess(Image.open("examples/pokemon.jpeg")).unsqueeze(0).to(device) |
|
text = clip.tokenize(["杰尼龟", "妙蛙种子", "小火龙", "皮卡丘"]).to(device) |
|
|
|
with torch.no_grad(): |
|
image_features = model.encode_image(image) |
|
text_features = model.encode_text(text) |
|
# Normalize the features. Please use the normalized features for downstream tasks. |
|
image_features /= image_features.norm(dim=-1, keepdim=True) |
|
text_features /= text_features.norm(dim=-1, keepdim=True) |
|
|
|
logits_per_image, logits_per_text = model.get_similarity(image, text) |
|
probs = logits_per_image.softmax(dim=-1).cpu().numpy() |
|
|
|
print("Label probs:", probs) |
|
``` |
|
<br><br> |
|
|
|
## Prediction and Evaluation |
|
|
|
### Download Image-text Retrieval Test Dataset |
|
In Project <b>[Chinese-CLIP](https://github.com/OFA-Sys/Chinese-CLIP)</b>, the test set has already been preprocessed. Here is the download link they provided: |
|
|
|
MUGE dataset：[download link](https://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/MUGE.zip) |
|
|
|
Flickr30K-CN dataset：[download link](https://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/Flickr30k-CN.zip) |
|
|
|
Additionally, obtaining the [COCO-CN](https://github.com/li-xirong/coco-cn) dataset requires applying to the original author. |
|
|
|
### Download ImageNet Dataset |
|
Please download the raw data yourself，[Chinese Label](http://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/ImageNet-1K/label_cn.txt) and [English Label](http://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/ImageNet-1K/label.txt) are provided by Project <b>[Chinese-CLIP](https://github.com/OFA-Sys/Chinese-CLIP)</b> |
