要使用GPU版本,复制tr_gpu文件夹里面的文件到tr文件夹
注意: 需要先安装CUDA 10.1以及cuDNN 7.6.5

若不想安装CUDA/cuDNN,可以使用docker部署
docker pull mcr.microsoft.com/azureml/onnxruntime:v1.3.0-cuda10.1-cudnn7
sudo nvidia-docker run -v /path/to/tr:/path/to/tr --rm -it mcr.microsoft.com/azureml/onnxruntime:v1.3.0-cuda10.1-cudnn7
#### Install + 安装方法一
git clone https://github.com/myhub/tr.git
cd ./tr
sudo python setup.py install
+ 安装方法二
sudo pip install git+https://github.com/myhub/tr.git@master
#### Test
python2 demo.py               # python2兼容测试     
python3 test.py               # 可视化测试
python3 test-multi-thread.py  # 多线程测试
#### 关联项目 + 若需要Web端调用,推荐参考TrWebOCR #### Python Example
import tr

# detect text lines, return list of (cx, cy, width, height, angle)
print(tr.detect("imgs/web.png", tr.FLAG_RECT))

# detect text lines with angle, return list of (cx, cy, width, height, angle)
print(tr.detect("imgs/id_card.jpeg", tr.FLAG_ROTATED_RECT))

# recognize text line, return (text, confidence)
print(tr.recognize("imgs/line.png"))

# detect and recognize text lines with angle, return list of ((cx, cy, width, height, angle), text, confidence)
print(tr.run("imgs/id_card.jpeg"))
#### C++ Example
tr_init(0, 0, "crnn.bin", NULL);

#define MAX_WIDTH		512
int unicode[MAX_WIDTH];
float prob[MAX_WIDTH]; 

auto ws = tr_recognize(0, (void *)"line.png", 0, 0, 0, unicode, prob, MAX_WIDTH);

tr_release(0);
