# 项目介绍
<br><br>
本项目旨在提供更好的中文CLIP模型。该项目使用的训练数据均为公开可访问的图像URL及相关中文文本描述，总量达到400M。经过筛选后，我们最终使用了100M的数据进行训练。
本项目于QQ-ARC Joint Lab, Tencent PCG完成

## 实验结果
针对图文检索任务，我们在[MUGE Retrieval](https://tianchi.aliyun.com/muge)、[Flickr30K-CN](https://github.com/li-xirong/cross-lingual-cap)和[COCO-CN](https://github.com/li-xirong/coco-cn)上进行了zero-shot测试。
针对图像零样本分类任务，我们在ImageNet数据集上进行了测试。测试结果见下表：

# 使用教程
## 安装要求
环境配置要求:

* python >= 3.6.4
* pytorch >= 1.8.0 (with torchvision >= 0.9.0)
* CUDA Version >= 10.2

安装本项目所需库
```bash
cd /yourpath/QA-CLIP-main
pip install -r requirements.txt
```

## 推理代码
```bash
export PYTHONPATH=/yourpath/QA-CLIP-main
```
推理代码示例：
```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)
    # 对特征进行归一化，请使用归一化后的图文特征用于下游任务
    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)
```

## 预测及评估

### 图文检索测试数据集下载
<b>[Chinese-CLIP](https://github.com/OFA-Sys/Chinese-CLIP)</b>项目中已经预处理好测试集，这是他们提供的下载链接：

MUGE数据：[下载链接](https://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/MUGE.zip)

Flickr30K-CN数据：[下载链接](https://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/Flickr30k-CN.zip)

另外[COCO-CN](https://github.com/li-xirong/coco-cn)数据的获取需要向原作者进行申请
### ImageNet数据集下载
原始数据请自行下载，[中文标签](http://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/ImageNet-1K/label_cn.txt)和[英文标签](http://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/datasets/ImageNet-1K/label.txt)同样由<b>[Chinese-CLIP](https://github.com/OFA-Sys/Chinese-CLIP)</b>项目提供
### 图文检索评估
图文检索评估代码可以参考如下：
```bash
split=test # 指定计算valid或test集特征
resume=your_ckp_path
DATAPATH=your_DATAPATH
dataset_name=Flickr30k-CN
# dataset_name=MUGE

python -u eval/extract_features.py \
    --extract-image-feats \
    --extract-text-feats \
    --image-data="${DATAPATH}/datasets/${dataset_name}/lmdb/${split}/imgs" \
    --text-data="${DATAPATH}/datasets/${dataset_name}/${split}_texts.jsonl" \
    --img-batch-size=32 \
    --text-batch-size=32 \
    --context-length=52 \
    --resume=${resume} \
    --vision-model=ViT-B-16 \
    --text-model=RoBERTa-wwm-ext-base-chinese

python -u eval/make_topk_predictions.py \
    --image-feats="${DATAPATH}/datasets/${dataset_name}/${split}_imgs.img_feat.jsonl" \
    --text-feats="${DATAPATH}/datasets/${dataset_name}/${split}_texts.txt_feat.jsonl" \
    --top-k=10 \
    --eval-batch-size=32768 \
    --output="${DATAPATH}/datasets/${dataset_name}/${split}_predictions.jsonl"

python -u eval/make_topk_predictions_tr.py \
    --image-feats="${DATAPATH}/datasets/${dataset_name}/${split}_imgs.img_feat.jsonl" \
    --text-feats="${DATAPATH}/datasets/${dataset_name}/${split}_texts.txt_feat.jsonl" \
    --top-k=10 \
    --eval-batch-size=32768 \
    --output="${DATAPATH}/datasets/${dataset_name}/${split}_tr_predictions.jsonl"

python eval/evaluation.py \
    ${DATAPATH}/datasets/${dataset_name}/${split}_texts.jsonl \
    ${DATAPATH}/datasets/${dataset_name}/${split}_predictions.jsonl \
    ${DATAPATH}/datasets/${dataset_name}/output1.json
cat  ${DATAPATH}/datasets/${dataset_name}/output1.json

python eval/transform_ir_annotation_to_tr.py \
    --input ${DATAPATH}/datasets/${dataset_name}/${split}_texts.jsonl

python eval/evaluation_tr.py \
    ${DATAPATH}/datasets/${dataset_name}/${split}_texts.tr.jsonl \
    ${DATAPATH}/datasets/${dataset_name}/${split}_tr_predictions.jsonl \
    ${DATAPATH}/datasets/${dataset_name}/output2.json

```

### ImageNet零样本分类
ImageNet零样本分类的代码参考如下
```bash
bash scripts/zeroshot_eval.sh 0 \
    ${DATAPATH} imagenet \
    ViT-B-16 RoBERTa-wwm-ext-base-chinese \
    ./pretrained_weights/QA-CLIP-base.pt
```
