.nb模型运行时报错PaddleLiteV2.12 remove XShape OutputTensor for SqueezeOp

[DarrenZhangug]

• 版本、环境信息：
     1）Paddle Lite 版本：paddle-lite V2.12
     2）Host 环境：RK3568
  3) 内核信息Linux 4.19.232#5 SMP Tue Nov aarch64 GNU/Linux
  4) 训练环境：PaddleOCR V2.9
• 模型信息
     1）模型名称 : ch_PP-OCRv4_rec_server_train
  2）配置文件：ch_PP-OCRv4_rec_hgnet.yml

复现流程
运行命令：./paddle_lite_ocr rec ch_ppocr_mobile_v2.0_rec_slim_opt.nb arm8 INT8 10 1 vis.jpg ppocr_keys_v1.txt config.txt

注意ch_ppocr_mobile_v2.0_rec_slim_opt.nb只是在使用opt工具转换时没改名字，实际上还是使用ch_PP-OCRv4_rec_server_train训练出的模型。

以下是运行结果：

• 问题描述：好像是说在PaddleLiteV2.12时移除了XShape OutputTensor导致的

• 报错图片：
  

• -做出的尝试：我尝试过替换成paddle-lite V2.13 V2.14这些预测库，结果都不行，也试过换成低版本的PaddleLite，如V2.10，2.10等，但是因为缺少paddle_use_kernels.h编译不过去。

• 目的：因为之间没接触过模型训练和识别类的东西，自己摸索到这里就不知道怎么下手了。希望有大佬能给我提供一些解决方法或者意见，万分感谢！！！

原始模型太老了，旧版本paddle导出的模型中会带XShape。建议用paddle2.6版本导出原始模型
