1、因为是内网环境，与阿里的技术测试私有pip源搞了两天，需要绑定IP白名单，还需要申请账户密码；
2、PPU-V1.7.0 PIP包清单-PG1阿里云产品-阿里云-真武 PPU 云服务(ppu)-阿里云帮助中心
以上是兼容性列表，结合操作系统版本、cuda版本和PPU固件版本，只能安装paddleocr 3.2.0和paddlepaddle-gpu 3.2.2
3、pip install paddleocr==3.2 -i xxx
pip install paddlepaddle-gpu==3.2.2 -i xxx
指定阿里给的私有镜像源安装
4、python import paddleocr提示libavcodec.so.61不存在
>>> from paddleocr import PaddleOCR No model hoster is available! Please check your network connection to one of the following model hosts: HuggingFace (https://huggingface.co), ModelScope (https://modelscope.cn), AIStudio (https://aistudio.baidu.com), or BOS (https://paddle-model-ecology.bj.bcebos.com). Otherwise, only local models can be used.

5、通过apt源安装ffmpeg，安装之后还是报上面的错误，在/usr/lib/x86_64-linux-gnu/下面看到的libavcodec版本是libavcodec.so.60。
6、因为通过源安装ffmpeg，默认版本是ffmpeg6，但libavcodec.so.61需要ffmpeg7版本，阿里、清华等源没有7版本，需要手动安装。
bash
wget https://ffmpeg.org/releases/ffmpeg-7.1.tar.xz
tar xf ffmpeg-7.1.tar.xz
cd ffmpeg-7.1
./configure --prefix=/usr/local
make -j$(nproc)
sudo make install安装过程可能提示缺一些别的系统包，用apt安装即可。
