About downloading tensorflow experience(1)

1. The most common problem is the slow download speed. The
solution is to add -i https://pypi.douban.com/simple after the download,
for example: pip install tensorflow -i https://pypi.douban.com /simple
Of course, you can also choose other mirrors

2. It is necessary to install 3.6 when installing python in conda, because I installed it but did not listen to other people’s blogs, so I did not configure it for a few days
