计算机网站建设实训总结郑州广告制作公司
背景
由于最近需要使用paddleocr，因此需要安装依赖paddlepaddle-gpu，不管怎么安装cuda11.6-11.8安装了一遍，都无法正常安装成功。如下所示：
环境：wsl2+linux18.04
>>> import paddle
>>> paddle.utils.run_check()
报错如下：
PreconditionNotMetError: Cannot load cudnn shared library. Cannot invoke method cudnnGetVersion.[Hint: cudnn_dso_handle should not be null.] (at ../paddle/phi/backends/dynload/cudnn.cc:64)[operator < fill_constant > error]
尝试

- 根据上面两位大佬的做法，无法解决；
- 怀疑是cuda和cudnn版本不一致，各种版本都试了一轮，也都无法解决；
docker
对paddle也是无语了，兼容性做的如此之差，谁还想继续使用下去（比torch、transformers库安装体验差多了），最后使用docker进行安装

- docker pull
nvidia-docker pull registry.baidubce.com/paddlepaddle/paddle:2.5.2-gpu-cuda11.7-cudnn8.4-trt8.4
- docker run
