运行

1. 下载相应模型和用于显示的字体文件
   • 提取码：30jv
   • 下载之后放在models目录即可
2. 运行rapidOCR.py文件, 即可

   cd python
   python rapidOCR.py

onnxruntime-gpu版推理配置

1. 安装GPU版的onnxruntime: pip install onnxruntime-gpu
2. 推理代码中，加载onnx模型部分，用以下对应语言代码替换即可,详细参见：官方教程
   • python版本

     import onnxruntime as ort
     
     model_path = '<path to model>'
     
     providers = [
        ('CUDAExecutionProvider', {
           'device_id': 0,
           'arena_extend_strategy': 'kNextPowerOfTwo',
           'gpu_mem_limit': 2 * 1024 * 1024 * 1024,
           'cudnn_conv_algo_search': 'EXHAUSTIVE',
           'do_copy_in_default_stream': True,
        }),
        'CPUExecutionProvider',
     ]
     
     session = ort.InferenceSession(model_path, providers=providers)
     

   • C/C++版本

     OrtSessionOptions* session_options = /* ... */;
     
     OrtCUDAProviderOptions options;
     options.device_id = 0;
     options.arena_extend_strategy = 0;
     options.gpu_mem_limit = 2 * 1024 * 1024 * 1024;
     options.cudnn_conv_algo_search = OrtCudnnConvAlgoSearch::EXHAUSTIVE;
     options.do_copy_in_default_stream = 1;
     
     SessionOptionsAppendExecutionProvider_CUDA(session_options, &options);
