Ubuntu 安装部署PaddleOCR过程
安装部署参考的官方文档在这里https://paddlepaddle.github.io/PaddleOCR/latest/ppocr/quick_start.html#211
1.搭建一个python的虚拟环境.
mkdir paddleocc
cd paddleocr
python -m venv .
cd bin
source activate
然后在命令行的提示语中就有(paddleocr)这个提示信息了.
2.安装相应的依赖
pip install --upgrade pip
pip install pysocks -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install paddlepaddle -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install paddleocr -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install pymupdf -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install pyfftw -i https://pypi.tuna.tsinghua.edu.cn/simple
sudo apt install -y ccache
sudo apt install libgomp1
3.验证安装是否正确
paddleocr -h
4.转码pdf文件
paddleocr --image_dir ./2.pdf --use_angle_cls true --use_gpu false
paddleocr --image_dir ./2.pdf --use_angle_cls true --use_gpu false --savefile true
输出如下:
