英文模型运行后 抛出java.lang.IndexOutOfBoundsException: Index 96 out of bounds for length 96 #33

Open biotech7 opened 1 year ago

biotech7 commented 1 year ago

系统环境: win11/jdk17/idea2022 djl环境: djl系列模块 版本 0.22.1 模型: 官方的英文 en_PP-OCRv3 检测和识别模型(https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/doc/doc_en/models_list_en.md) 模型转换: 按本项目引导成功转换成onnx模型，在转换检测模型时，预先用paddle_infer_shape.py模块对检测模型的shape进行修改，关键修改参数设置为：--input_shape_dict="{'x':[-1,3,-1,-1]}，然后再转换模型，并成功转换成onnx格式 应用字典(ppocr_keys_v1.txt): 官方的ppocr_keys_v1.txt，但识别出来的是乱码，后改为en_dict.txt，含95个字符的字典 (https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/ppocr/utils/en_dict.txt)

测试模型(en_dict.txt中的字符作为字典内容)，识别一张全英文图片，抛出异常java.lang.IndexOutOfBoundsException: Index 96 out of bounds for length 96。是不是在修改检测模型shape时参数设置错误？或者字典选择错误？好像其它地方都没有太多疑问，因为运行项目中的ch_PP-OCRv3_rec_infer_onnx模型是正常的。恳请老师帮我拨开云雾，再次感谢老师的无私杰出奉献。 核心错误信息如下：
