windows上安裝tensorflow時報錯,“DLL load failed: 找不到指定的模塊”怎么辦

這篇文章主要為大家展示了windows上安裝tensorflow時報錯,“DLL load failed: 找不到指定的模塊”怎么辦，內容簡而易懂，希望大家可以學習一下，學習完之后肯定會有收獲的，下面讓小編帶大家一起來看看吧。

最近打算開始研究一下機器學習，今天在windows上裝tensorflow花了點功夫，其實前面的步驟不難，只要依次裝好python3.5，numpy，tensorflow就行了，有一點要注意的是目前只有python3.5能裝tensorflow，最新版的python3.6都不行。

裝好tensorflow后，我建議大家不要直接用測試用例進行測試（如果沒裝好的話出現的錯誤一般都是：module ‘tensorflow' has no attribute ‘constant'）。第一次測試時可以在python shell里面輸入：

import tensorflow

如果沒有報錯，恭喜你，十有八九是裝好了，這時可以再用簡單的測試用例測試一下。但我估計沒報錯的話你也不會看到這篇博客了。。。

事實上，我第一次安裝的時候出現了如下錯誤：

之前在網上查安裝方法時，大多數都說要裝一個Anaconda，但我是直接裝的python3.5，所以沒裝Anaconda，我相信問題不在這里。后來看到有人說裝了visual studio2017解決了這個錯誤，我想不至于吧，裝個tensorflow還要裝個visual studio2017？事實上只是visual studio2017中剛好有運行tensorflow必須的運行時環境。所以，只要安裝一下缺少的運行時環境就可以了，可以在如下網站中按照它的install instructions進行安裝，非常簡單，只要注意選對32位和64位的版本就行了。

裝好后tensorflow就可以正常使用了~
