升级tensorflow到最新版本
但是速度很慢
pip install -U tensorflow
pip3 install --upgrade tensorflow
清华园
i https://pypi.tuna.tsinghua.edu.cn/simple
清华园安装
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple/ --upgrade tensorflow
下载过程中出现six不能卸载情况
pip3 install tensorflow –ignore-installed six
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple/ --upgrade tensorflow --ignore-installed six
解决思路
由于环境原因，无法安装程序包错误：[WinError 5]拒绝访问
解决方法
考虑使用“–user”选项或检查权限
最终可行口令
pip3 install --user -i https://pypi.tuna.tsinghua.edu.cn/simple/ --upgrade tensorflow --ignore-installed six
