paddleocr报错：Hint: cudnn_dso_hand

1. 安装cudatoolkit

先查看cuda版本：nvidia-smi

然后到 CUDA Toolkit 12.1 Update 1 Downloads | NVIDIA Developer 下载对应版本

wget https://developer.download.nvidia.com/compute/cuda/11.1.0/local_installers/cuda_11.1.0_455.23.05_linux.run

sudo sh  cuda_11.1.0_455.23.05_linux.run

accept 然后取消Driver,一路回车

配置环境变量：

vim ~/.bashrc

文末添加

export PATH=/usr/local/cuda-11.1/bin${PATH:+:${PATH}} export LD_LIBRARY_PATH=/usr/local/cuda-11.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

source ~/.bashrc

然后切换cuda

ln -snf /usr/local/cuda-11.1 /usr/local/cuda

2. 下载cuDNN Archive | NVIDIA Developer，解压后将cudnn.h移到cuda路径的include中，将libcudnn*移动到cuda路径的lib64中：

sudo cp cuda/include/cudnn.h /usr/local/cuda/include/

sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/

sudo chmod a+r /usr/local/cuda/include/cudnn.h

sudo chmod a+r /usr/local/cuda/lib64/libcudnn*
