安装tensorflow报错：ImportError: DLL load failed: 动态链接库(DLL)初始化例程失败之解决方案


我是在Windows环境下，使用Anaconda3的python3.6.3环境，安装TensorFlow最简单的CPU版本(我老婆的笔记本不支持GPU，没有nvidia的显卡)：


管理员身份运行cmd，然后进入环境执行：pip install tensorflow


安装过程非常顺利，Python中  import tensorflow 报错：
Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\envs\tensor_flow\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "C:\ProgramData\Anaconda3\envs\tensor_flow\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 17, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "C:\ProgramData\Anaconda3\envs\tensor_flow\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 16, in swig_import_helper
    return importlib.import_module('_pywrap_tensorflow_internal')
  File "C:\ProgramData\Anaconda3\envs\tensor_flow\lib\importlib\__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named '_pywrap_tensorflow_internal'

During handling of the above exception, another exception occurred:

解决方案：tensorflow新旧版本的兼容性问题，默认安装没有指定版本则会安装最新的稳定版本1.10


根本原因是自己的电脑不新，CPU尽管是Intel的，但不新也许太老不主流了，
TensorFlow的新版本已不打算继续支持这种CPU了。
所以我尝试1.3版本的TensorFlow是OK的，但最新的1.8版本就报错了(1.4版本会有个warning)。
