1.首先安装docker和nvidia-docker
https://blog.csdn.net/u013171226/article/details/115113220
2.准备docker环境
官网上面说明了CPU版本、cuda9版本、cuda10版本的docker环境创建命令，但是我的电脑是cuda11，因此我直接去 https://hub.docker.com/r/paddlepaddle/paddle/tags/ 网站找到下面的
然后pull镜像文件。
docker pull paddlepaddle/paddle:2.0.1-gpu-cuda11.0-cudnn8然后根据下载的镜像文件创建docker容器。
sudo nvidia-docker run --name ppocr -v $PWD:/paddle --network=host -itd paddlepaddle/paddle:2.0.1-gpu-cuda11.0-cudnn8 /bin/bash然后用docker ps看一下当前运行的docker容器
docker ps #查看当前运行的docker容器。
docker ps -a #查看所有存在的docker容器。结果如下：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
99aba9e2659f paddlepaddle/paddle:2.0.1-gpu-cuda11.0-cudnn8 "/bin/bash" About an hour ago Up About an hour ppocr
然后我们根据ID号进入docker环境：
docker exec -it 99aba9e2659f /bin/bash2.克隆PaddleOCR repo代码
cd /paddle/
git clone https://github.com/PaddlePaddle/PaddleOCR
3.安装第三方库
cd PaddleOCR
pip3 install -r requirments.txt刚开始运行的时候提示下面的错误：
ERROR: Could not find a version that satisfies the requirement scikit-image==0.17.2
ERROR: No matching distribution found for scikit-image==0.17.2
然后Python -V发现是Python3.5。怀疑是使用的Python和pip版本比较低，导致找不到0.17.2的版本。然后
λ boyun-DGX-1-with-V100-32 /paddle/PaddleOCR {release/2.0} find / -iname "python"

发现里面其实python3.5,python3.6,python3.7都有的，于是执行
ln -snf /usr/bin/python3.7 /usr/bin/python3同样对于pip3，
λ boyun-DGX-1-with-V100-32 /paddle/PaddleOCR {release/2.0} find / -iname "pip"

/usr/local/lib/python3.8/dist-packages/pip-20.0.1-py3.8.egg/pip
/usr/local/bin/pip
执行
ln -snf /usr/local/bin/pip3.7 /usr/local/bin/pip3然后再执行pip3 install -r requirments.txt就可以安装成功了。
