tensorflow安装
TensorFlow下载和安装详解（两种常用方式） | 艾奇编程网 (91yiqixue.com)
pip install tensorflow==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
碰到错误信息解决错误信息（大概3-4个错误信息）
错误信息
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
解决方式
直接忽略旧版本进行升级：
pip install six --upgrade --ignore-installed six
验证是否安装成功：
conda list
或在pycharm中的python文件输入如下程序：
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
hello = tf.constant('ggg!')
sess = tf.compat.v1.Session()
print(sess.run(hello))
观察结果是否能够打印
如果想将tensorflow升级 则重新安装下 运行下面代码 将2.0.0更改为想装的版本
pip install tensorflow==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
