安装tensorFlow

步骤：
1.下载anaconda虚拟环境，默认安装
2.下载CUDA-tools，默认安装 。测试是否成功方法，打开命令行，输入nvcc -V 看到类似如下版本号等信息就是成功

(TensorFlowGPU3_9) C:\Users\qinsi>nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Fri_Dec_17_18:28:54_Pacific_Standard_Time_2021
Cuda compilation tools, release 11.6, V11.6.55
Build cuda_11.6.r11.6/compiler.30794723_0

3.在anaconda中选择environments 选择中间最下面的create，创建默认环境TensorFlowGPU3_9
4.点三角号启动,选择Open Terminal
5.输入pip install tensorflow-gpu
注意：如报错，可尝试先安装pip install pip-search

6.安装完成后，python执行，然后

import tensorflow as tf
hello = tf.constant(‘hello,tf’)
sess = tf.compat.v1.Session()

输出显卡信息：
