ml的检测效果很烂，所以都用的en的检测器
没有ru的rec，所以用cyrillic简单替代


paddle2onnx
paddle2onnx --model_dir ./  --model_filename inference.pdmodel --params_filename inference.pdiparams --save_file 1.onnx --opset_version 11 --enable_onnx_checker True

https://github.com/PaddlePaddle/PaddleOCR/issues/1048 这里面有很多其他语言的，但转换onnx不管用
