armv7hf lite部署，使用1.1模型只能检测无法识别。使用2.0模型，运行segmentfault

[zsun14]

环境：
paddleocr develop版本
paddle-lite 使用2.8的release， inference_lite_lib.armlinux.armv7hf.gcc.with_extra.with_cv.tar

崩溃步骤：
1 编译paddle-ocr deploy lite
按照readme操作
由于要运行在树莓上，所以剥离了对NDK的依赖，重新编译了opencv4.1，生成ocr_db_crnn

2 使用linux_opt 对分别对det cls rec模型优化
模型使用pp-orc 2.0的ch_ppocr_mobile_v2.0_det ch_ppocr_mobile_v2.0_rec ch_ppocr_mobile_v2.0_cls
./opt_linux
--model_file=./ch_ppocr_mobile_v2.0_det_infer/inference.pdmodel
--param_file=./ch_ppocr_mobile_v2.0_det_infer/inference.pdiparams
--optimize_out_type=naive_buffer
--optimize_out=./det --valid_targets=arm

rec和cls同上

3 执行崩溃

无法识别步骤：
1 使用此前编译程序

2 下载1.1模型，使用2.8的opt进行优化

3 执行，可以定位文字区域，但无识别结果。

1.1 模型，建议用paddle lite 2.7分支，在arm8上测试是可以的

2.0模型，建议用paddle lite 2.8分支，而且2.0模型的lite代码还没上传，和1.1模型的lite代码有些不一样，所以用2.0的模型会出现段错误
