paddle-lite v2.11的版本就会出现这个问题，换成v2.10版本就可以解决，但是v2.10版本对ch_PP-OCRv2_rec_slim_opt.nb又有问题 https://github.com/PaddlePaddle/PaddleOCR/issues/5808

@an1018 就是按照文档步骤来的，复现的方法就是把paddlelite版本换成v2.11，你们可以测试一下，分类模型ch_PP-OCRv3_rec_slim_opt.nb会出现乱码。

@OPHoperHPO It works well with fp32, but fp16 sometimes produces completely black results, possibly due to numerical overflow. Is there a way to solve?

@K-prog I use MNN to convert the model to FP16 format, just like what was mentioned in this issue. Only some images have issues. https://github.com/alibaba/MNN/issues/2977
