TensorFlow报错：
python或者anaconda运行时显示：
一般的解决方案：
pip install --upgrade --ignore-installed tensorflow
或者
pip install --user --upgrade --ignore-installed tensorflow
在DOS窗口运行结果如下：
输入以下命令也是报错：
pip install --upgrade --ignore-installed tensorflow-gpu
pip3 install tensorflow #cpu
pip3 install tensorflow-gpu
那么------既然找不到TensorFlow的版本，那我们就自行查找，输入：
pip3 search tensorflow

安装不成功的原因是：
1：电脑是32bit的
2：Python版本高于3.6

如下图：Python是3.9 环境是64bit
版本高于3.6,打开Anaconda查看其Python版本
安装TensorFlow方法：
CPU版本的安装
pip install --ignore-installed --upgrade tensorflow
安装步骤：
1：TensorFlow在Windows下，支持Python 3.6版本
2：在DOS窗口中输入：[目的：输入清华仓库镜像，加快更新速度]
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
3：然后再输入：
conda config --set show_channel_urls yes
4：Anaconda3创建一个python3.6的环境，环境名称为tensorflow ，命令如下：
conda create -n tensorflow python=3.6
anaconda在这里的意思安装依赖包，所以要下载一会~~~~
5：询问是否安装:
6：输入
>> y
然后开始出现下图的趋势：
-----done-------
此时的Anaconda已经显示在更新新动态
打开Anaconda>>Environments 就可看到TensorFlow的选项：
表示TensorFlow的环境已经建好：
7：在Anaconda的启动TensorFlow：
activate tensorflow
8：安装cpu版本的TensorFlow
pip install --upgrade --ignore-installed tensorflow
响应结果如下图：
当不使用TensorFlow时，可以通过deactivate来关闭TensorFlow环境：
>> deactivate
9:测试cpu版本的TensorFlow:
先启动：activate tensorflow
再进入Python：python
