最近開始學習tensorflow，電腦是win10 64位系統的，已經安裝了python3.6.1 32位的，tensorflow只支援python64位的，所以直接安裝了Python64位３.6.1。直接使用pip install tensorflow安裝，安裝的是1.8.0版本，安裝好後在命令列中執行import tensorflow出現問題，無法成功，現象如下： Microsoft Windows [版本 10.0.16299.371]

1、經過網上搜索，參考

http://blog.csdn.net/pjl6523853/article/details/72836214的解答是沒有安裝vc64位執行庫，直接微軟體官網下載了，安裝後，執行import tensorflow還是老樣子。 2、看來問題還是沒有解決，繼續搜尋，找到了這個 博文的解決法，試過之後可以了。
     問題的原因是我的電腦（聯想V460）的cpu比較老，不支援AVX指令導致的，需要安裝特殊編譯的 tensorflow 1.6.0版本才可以解決，注意安裝時要先解除安裝先前安裝的1.8.0版本。關於這個問題的詳細解決過程可以參考

github上面tensorflow的論壇。
以上兩步操作完成，問題解決了。編寫一個簡單的程式測試一下，OK了。

把上面的程式碼寫到py檔案中，使用python 3.6 shell執行，出現不識別tensorflow模組的問題。

        分析原因是由於電腦上同時安裝了python 3.6.1 32位和64位的問題，shell執行時還是載入的32位python的安裝包，所以還要想辦法解決一下32位和64位shell同時共存的問題，因為python3.6.1 32位已經編寫了很多軟體，還不能解除安裝。        這個問題解決的，原因很簡單，定義用於測試的檔案不能命名使用tensorflow.py，換成其他名字就好了。python32, python64在同一個電腦的包管路徑是不會衝突的，不需要做額外修改。
