paddleocr gpu编译问题

报错

修改cpp_infer/include/utility.h

文件中添加头文件

#include <numeric>

 

 

1.编译报错为make[2]: *** 没有规则可制作目标“/home/ceshi/workspace/paddle_inference/third_party/install/onednn/lib/libmkldnn.so.0”，由“ppocr” 需求。

下载paddle编译库但是编译的时候会缺少东西

 报错信息为make[2]: *** 没有规则可制作目标“/home/ceshi/workspace/paddle_inference/third_party/install/onednn/lib/libmkldnn.so.0”，由“ppocr” 需求。

 需要去fastdelpy

https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install/download_prebuilt_libraries.md

在对应的paddle_infrene中的这个路径下

 

 直接拷贝过去就可以了

 

2*** 没有规则可制作目标“/lib/libnvinfer.so”，由“ppocr” 需求。 

编译缺少trt的依赖，使用下面的编译就可以了最好使用静态库

OPENCV_DIR=/home/ceshi/workspace/opencv347
LIB_DIR=/home/ceshi/workspace/paddle_inference
CUDA_LIB_DIR=/usr/local/cuda-12.3/lib64
CUDNN_LIB_DIR=/usr/local/cuda-12.3/lib64
TENSORRT_DIR=/home/ceshi/opt/TensorRT-8.6.1.6

BUILD_DIR=build
# rm -rf ${BUILD_DIR}
# mkdir ${BUILD_DIR}
cd ${BUILD_DIR}
cmake .. \
    -DPADDLE_LIB=${LIB_DIR} \
    -DWITH_MKL=ON \
    -DWITH_GPU=ON \
    -DWITH_STATIC_LIB=OFF \
    -DWITH_TENSORRT=ON \
    -DOPENCV_DIR=${OPENCV_DIR} \
    -DCUDNN_LIB=${CUDNN_LIB_DIR} \
    -DCUDA_LIB=${CUDA_LIB_DIR} \
    -DTENSORRT_DIR=${TENSORRT_DIR} \

make -j

Linux中添加

安装 zlib 开发库
​Ubuntu/Debian 系统
sudo apt update && sudo apt install zlib1g-dev  # 安装动态库和头文件[1,7,8](@ref)
​验证安装：检查库文件是否存在：
ls /usr/lib/x86_64-linux-gnu/libz.*  # 正常应显示 libz.so 和 libz.a

 

 

3.报错没有环境变量这个最简单添加环境变量

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ceshi/workspace/paddle_inference/third_party/install/onednn/lib:/home/ceshi/workspace/paddle_inference/third_party/install/mklml/lib

　　

4.没用使用上GPU

需要更改代码对应位置改为true
