安装正常来说是肥肠简单的
官方安装：Installing TensorFlow on Windows
一步步的进行没有问题，安装也安装上了，一运行：

import tensorflow as tfTraceback (most recent call last):  File "D:\Program Files\Python35\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 18, in swig_import_helper    return importlib.import_module(mname)  File "D:\Program Files\Python35\lib\importlib\__init__.py", line 126, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "<frozen importlib._bootstrap>", line 986, in _gcd_import  File "<frozen importlib._bootstrap>", line 969, in _find_and_load  File "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked  File "<frozen importlib._bootstrap>", line 666, in _load_unlocked  File "<frozen importlib._bootstrap>", line 577, in module_from_spec  File "<frozen importlib._bootstrap_external>", line 906, in create_module  File "<frozen importlib._bootstrap>", line 222, in _call_with_frames_removedImportError: DLL load failed: 找不到指定的模块。During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "D:\Program Files\Python35\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 41, in <module>    from tensorflow.python.pywrap_tensorflow_internal import *  File "D:\Program Files\Python35\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 21, in <module>    _pywrap_tensorflow_internal = swig_import_helper()  File "D:\Program Files\Python35\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 20, in swig_import_helper    return importlib.import_module('_pywrap_tensorflow_internal')  File "D:\Program Files\Python35\lib\importlib\__init__.py", line 126, in import_module    return _bootstrap._gcd_import(name[level:], package, level)ImportError: No module named '_pywrap_tensorflow_internal'During handling of the above exception, another exception occurred:

按理说查了一圈，找到网上说出现的问题：
1少cudnn路径（相信你一定下载了并且解压了），加入path即可
2Microsoft Visual C++ 2015 Redistributable Package (x86) 确保有这个
附上链接：http://www.microsoft.com/en-us/download/details.aspx?id=53587
3 python 必须是3.5版本（3.6目前也好使了，亲测可用）
在确保各种路径都加了绝对能找到dll之后，仍然报错
回到官网安装教程再仔细看了一遍发现：

If you have a different version of one of the preceding packages, please change to the specified versions. In particular, the cuDNN version must match exactly: TensorFlow will not load if it cannot find cuDNN64_6.dll. To use a different version of cuDNN, you must build from source.

so，自己的cudnn版本错了，回去检查了下，果然是，重新下载了6.0版本，确实是cuDNN64_6.dll，之后，运行成功

同样tensorflow里面这个问题也列出了我所面临的情况:

遇到问题去网上大部分都在说1，2，3那种问题（汉语博客，当然也首先看汉语），导致浪费了一些时间
哎，仔细阅读官方安装教程才是王道。。。。。
