安装paddle的时候，需要提前安装cuda和cudnn吗？ 我直接使用命令conda install paddlepaddle-gpu==2.3.0 cudatoolkit=11.2 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ -c conda-forge
然后安装完，验证失败了。

然后我去anaconda下载了一个mkl的mkl-2022.0.0-haa95532_115.tar包，然后在我的(paddle_env) C:\Users\Administrator>conda install mkl-2022.0.0-haa95532_115.tar报错：

看报错信息是 http 网络代理有问题，可以先检查下网络代理。

谢谢，我想问的是，如果是GPU版本的，是不是需要在电脑上独立的安装一个CUDA？ 还是说不需要额外安装，直接使用这一句conda install paddlepaddle-gpu==2.3.0 cudatoolkit=11.2 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ -c conda-forge
就默认的安装带的就又cuda加速和cudnn计算的？

有CUDA驱动就可以，不需要单独安装cuda和cudnn；
如果网络不好，可以下载到本地安装，下载链接： https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/win-64/
安装命令：
conda install -c local xxx.tar.bz2; conda install -c local paddlepaddle-gpukxkpmulp6#
conda install paddlepaddle-gpu==2.3.0 cudatoolkit=11.2 之后，不需要再额外安装一个独立的 CUDA。
