Win11极速安装Tensorflow-gpu+CUDA+cudnn

不要使用官网版本，直接使用conda版本，有对应的包，安装很方便

0.pip/conda换默认源

为了高效下载，建议先把默认源换了，很简单这里不再赘述。（我用梯子，所以没换源😋）



cudnn7.6.0 + cuda10.1.168 +tensorflow-gpu2.3.0

1.Anaconda+python虚拟环境

如果你需要用到tensorflow了那我相信你一定会用Anaconda，Anaconda的安装不再赘述。只是提个醒，如果你第一次用conda create -n创建环境那么路径一定在C盘，而换默认路径一定是可以设置的，这里也不再展开
创建TensorFlow环境：(tf是环境名字，尽量取短点吧，要不然以后手都输麻)

conda create -n tf python=3.9

2.安装CUDA以及cudnn

找到NVIDIA控制面板->帮助->系统信息->组件看一下CUDA版本，我的12.0是目前最新的，一般向下兼容

先试试cudatoolkit11.3.1和cudnn8.2.1

conda search cuda

测试tensorflow的GPU版本安装成功的办法

import tensorflow as tf

print('GPU',tf.test.is_gpu_available())

a = tf.constant(2.)
b = tf.constant(4.)

print(a * b)

运行结果
