安裝好Pytorch後，在官網逗留一小段時間後，感覺有些乏懵，於是乘勝追擊，將tensorflow安裝上。

首先：

我在安裝Pytorch之前試了一次，失敗了

然後我按照上一篇部落格成功安裝上Pytorch。

朋友們，有誰能告訴我，誰在我用電腦的這兩個小時偷偷給我裝好了tensorflow 麼？其實在安裝之前去檢視過中文版官網(http://www.tensorfly.cn/)，顯示只支援python2.7版本，並且沒有win下的安裝。

我翻回去檢視Pytorch和torchvision安裝過程中，也就自己安裝了numpy和pillow這兩個庫，所以一臉懵逼，大家可以試一試。

雖然我知道這樣搞可能這個環境不夠robust，但是誰就我們是新手，是自學呢，當你踩過所有的坑，相信這些坑能使你更加robust。
