同时import paddle和torch报错找不到cudnn

[lyxxxyl]

bug描述 Describe the Bug

发生了和 66669# 一样的问题
同时import torch 和import paddle 时将会报错

Traceback (most recent call last):
  File "D:\Project\PyC\demo.py", line 117, in <module>
    import torch
  File "D:\Python3\lib\site-packages\torch\__init__.py", line 122, in <module>
    raise err
OSError: [WinError 127] 找不到指定的程序。 Error loading "D:\Python3\lib\site-packages\torch\lib\cudnn_adv_train64_8.dll" or one of its dependencies.

应该与 这个问题 是类似的，先import torch或paddle都会报错。
我的环境是CUDA 11.8，cudnn 8.6.0，python 3.8.0

paddle是按照官网命令下载的，之前用的是paddlepaddle 2.6-cuda11.7，与pytorch同时引用会报错gpu占用问题，和 142#，按照里面的方法重新下了paddle
python -m pip install --pre paddlepaddle-gpu -i https://www.paddlepaddle.org.cn/packages/nightly/cu118/

单独使用时两个库都正常，且可以使用gpu加速
但是显示的cudnn版本都与我系统所安装的不同
系统所安装的cudnn为 cudnn-windows-x86_64-8.6.0.163_cuda11-archive 是按照Paddle官网所要求

验证paddle安装没有问题

import paddle
paddle.utils.run_check()

输出为

PaddlePaddle works well on 1 GPU.

且使用paddleocr正常

验证torch

import torch
print(torch.cuda.is_available())
print(torch.backends.cudnn.is_available())
print(torch.cuda_version)
print(torch.backends.cudnn.version())

输出为

True
True
11.8
8700

发现两个cudnn版本都不是系统中所装的cudnn 8.6.0，是否真如 604# 中的评论所说一样，该如何解决呢

参考这个issue #56812, paddle换成paddle-gpu 2.4.0试试呢

上面发的报错是先import paddle 再 import torch的，先torch 后 paddle报错如下

Traceback (most recent call last):
  File "D:\Project\PyC\demo.py", line 115, in <module>
    import paddle
  File "D:\Python3\lib\site-packages\paddle\__init__.py", line 721, in <module>
    raise err

这个办法是可以的，我之前用paddle-gpu 2.4.2-post117和 torch 1.13.0-cu117是可行的
就是会报一堆警告

我看 142# 的方法还以为新版本解决了，想试一下，然后就报了这样的错误

paddle怎么老解决不了这种环境问题？
